MAX16993: Step-Down Controller with Dual 2.1MHz Step-Down DC-DC Converters

February 08, 2014 10:32 AM - Maxim - Data Sheets --
The MAX16993 power-management integrated circuit (PMIC) is a 2.1MHz, multichannel, DC-DC converter designed for automotive applications. The device integrates three supplies in a small footprint. The device includes one high-voltage step-down controller (OUT1) designed to run directly from a car battery and two low-voltage step-down converters (OUT2/OUT3) cascaded from OUT1. Under no-load conditions, the MAX16993 consumes only 30µA of quiescent current, making it ideal for automotive applications.



The high-voltage synchronous step-down DC-DC controller (OUT1) operates from a voltage up to 36V continuous and is protected from load-dump transients up to 42V. There is a pin-selectable frequency option of either 2.1MHz or a factory-set frequency for 1.05MHz, 525kHz, 420kHz, or 350kHz. The low-voltage, synchronous step-down DC-DC converters run directly from OUT1 and can supply output currents up to 3A.



The device provides a spread-spectrum enable input (SSEN) to provide quick improvement in electromagnetic interference when needed. There is also a SYNC I/O for providing either an input to synchronize to an external clock source or an output of the internally generated clock (see the Selector Guide in the full data sheet). The device includes overtemperature shutdown and overcurrent limiting. The device also includes individual active-low RESET_ outputs and individual enable inputs. The active-low RESET_ outputs provide voltage monitoring for all output channels.



The MAX16993 is available in a 32-pin TQFN/side-wettable QFND-EP package and is specified for operation over the -40°C to +125°C automotive temperature range.

MAX44241, MAX44243, MAX44246: 36V, Low-Noise, Precision, Single/Quad/Dual Op Amps

February 08, 2014 10:32 AM - Maxim - Data Sheets --
The MAX44241/MAX44243/MAX44246 are 36V, ultra-precision, low-noise, low-drift, single/quad/dual operational amplifiers that offer near-zero DC offset and drift through the use of patented chopper stabilized and auto-zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. These single/quad/dual devices feature rail-to-rail outputs, operate from a single 2.7V to 36V supply or dual ±1.35V to ±18V supplies, and consume only 0.42mA per channel, with only 9nV/ input-referred voltage noise.



The ICs are unity-gain stable with a gain-bandwidth product of 5MHz. With excellent specifications such as offset voltage of 5µV (max), drift of 20nV/°C (max), and 117nVP-P noise in 0.1Hz to 10Hz, these ICs are ideally suited for applications requiring ultra-low noise, and DC precision such as interfacing with pressure sensors, strain gauges, precision weight scales, and medical instrumentation.



The ICs are available in 8-pin µMAX(r) or SO packages and are rated over the -40°C to +125°C temperature range.

MAX16046, MAX16048: 12-/8-Channel EEPROM-Programmable System Managers with Nonvolatile Fault Registers

February 08, 2014 10:32 AM - Maxim - Data Sheets -- The MAX16046/MAX16048 EEPROM-configurable system managers monitor, sequence, track, and margin multiple system voltages. The MAX16046 manages up to twelve system voltages simultaneously, and the MAX16048 manages up to eight supply voltages. These devices integrate an analog-to-digital converter (ADC) for monitoring supply voltages, digital-to-analog converters (DAC) for adjusting supply voltages, and configurable outputs for sequencing and tracking supplies (during power-up and power-down). Nonvolatile EEPROM registers are configurable for storing upper and lower voltage limits, setting timing and sequencing requirements, and for storing critical fault data for readback following failures.

An internal 1% accurate 10-bit ADC measures each input and compares the result to one upper, one lower, and one selectable upper or lower limit. A fault signal asserts when a monitored voltage falls outside the set limits. Up to three independent fault output signals are configurable to assert under various fault conditions.

The integrated sequencer/tracker allows precise control over the power-up and power-down order of up to twelve (MAX16046) or up to eight (MAX16048) power supplies. Four channels (EN_OUT1–EN_OUT4) support closed-loop tracking using external series MOSFETs. Six outputs (EN_OUT1–EN_OUT6) are configurable with charge-pump outputs to directly drive MOSFETs without closed-loop tracking.

The MAX16046/MAX16048 include twelve/eight integrated 8-bit DAC outputs for margining power supplies when connected to the trim input of a point-of-load (POL) module.

The MAX16046/MAX16048 include six programmable general-purpose inputs/outputs (GPIOs). GPIOs are EEPROM configurable as dedicated fault outputs, as a watchdog input or output (WDI/WDO), as a manual reset (active-low MR), or for margin control inputs.

The MAX16046/MAX16048 feature two methods of fault management for recording information during system shutdown events. The fault logger records a failure in the internal EEPROM and sets a lock bit protecting the stored fault data from accidental erasure.

An I²C or a JTAG serial interface configures the MAX16046/MAX16048. These devices are offered in a 56-pin 8mm x 8mm TQFN package or a 64-pin 10mm x 10mm TQFP package and are fully specified from -40°C to +85°C.

MAX14808, MAX14809: Octal Three-Level/Quad Five-Level High-Voltage 2A Digital Pulsers with T/R Switch

January 23, 2014 10:35 AM - Maxim - Data Sheets -- The MAX14808/MAX14809 octal three-level/quad five-level, high-voltage (HV) pulser devices generate high-frequency HV bipolar pulses (up to ±105V) from low-voltage control logic inputs for driving piezoelectric transducers in ultrasound systems. All eight channels have embedded overvoltage-protection diodes and integrated active return-to-zero clamp. Both devices have embedded independent (floating) power supplies (FPS) and level shifters that allow signal transmission without the need for external HV capacitors. The MAX14808 also features eight integrated transmit/receive (T/R) switches. The MAX14809 does not have the T/R switch function.

The devices feature two modes of operation: an octal three-level pulser mode (with integrated active return-to-zero clamp) or a quad five-level pulser mode. In octal three-level pulser mode, each channel is controlled by two logic inputs (DINN_/DINP_) and the active return to zero features half the current driving of the pulser 1A (typ). In quad five-level pulser mode, each channel is controlled by three logic inputs and the active return to zero has the same current driving of the pulser 2A (typ).

The devices can operate both in clocked and transparent mode. In clocked mode, data inputs can be synchronized with a clean differential or single-ended clock to reduce phase noise associated with FPGA output signals that are detrimental for Doppler analysis. In transparent mode, the synchronization feature is disabled and output reflects the data input after a 18ns delay. Both devices feature adjustable maximum current (0.5A to 2A) to reduce power consumption when full current capability is not required.

The devices feature integrated grass-clipping diodes (with low parasitic capacitance) for receive (Rx) and transmit (Tx) isolations. Both devices feature a damping circuit that can be activated as soon as the transmit burst is over. The damping circuit has a typical on-resistance of 500Ω. It fully discharges the pulser's output internal node before the grass-clipping diodes.

The devices are available in a 68-pin (10mm x 10mm) TQFN package with an exposed pad and are specified over the -40°C to +85°C extended temperature range.

A switching frequency of 1.5MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The switching regulators use current mode control and are internally compensated, reducing external parts count. Each converter automatically transitions to Burst Mode operation to maintain high efficiency over the full load range. Burst Mode operation can be disabled for low noise applications. The integrated LDO provides a third low noise, low dropout supply.
Anti-ringing circuitry reduces EMI by damping the boost inductor in discontinuous mode. Additional features include shutdown current of under 1μA and overtemperature shutdown. The LTC3100 is housed in a 16-lead 3mm × 3mm 0.75mm QFN package.
