TPS65941111RWERQ1

The Texas Instruments TPS65941111RWERQ1 is a highly integrated Power Management IC (PMIC) specifically qualified for automotive applications. This device is AEC-Q100 qualified and operates within an input voltage range of 2.8 V to 5.5 V, with an ambient operating temperature range of -40°C to +125°C.

This PMIC features five step-down (BUCK) switched-mode power supply regulators and four low-dropout (LDO) linear regulators. The BUCK regulators offer output voltages from 0.3 V to 3.34 V, with individual current capabilities up to 4 A and a combined multi-phase capability of up to 14 A. The LDO regulators provide output voltages from 0.6 V to 3.3 V, with current capabilities up to 500 mA.

Designed for functional safety applications, the TPS65941111RWERQ1 includes features like input supply voltage monitoring, over-voltage protection, under/overvoltage monitors on outputs, over-current monitors, watchdog timer, error signal monitors, and thermal monitoring with shutdown. It supports configurable power sequence control via non-volatile memory (NVM).

The device is housed in a 56-pin VQFNP package measuring 8 mm x 8 mm with a 0.5 mm pitch. It supports SPI or dual I2C control interfaces and is suitable for automotive infotainment, digital clusters, navigation systems, and telematics.
