IC revisionA

Description

The LP87725-Q1 device is designed to meet the power management requirements of the AWR and IWR MMICs in various automotive and industrial radar applications. The device has three step-down DC/DC converters, a LDO regulator and a load switch. The LDO is powered externally and intended for Ethernet device core supply. The load switch is intended to cut off the 3.3V IO supply during the sensor sleep mode. The device is controlled by an I²C serial interface and by enable signal.

Features

  • Evaluation of LP87725-Q1 device features and performance
  • Onboard wide-VIN preregulator to generate 3.3V input to the PMIC from 12V battery supply
  • Onboard microcontroller to communicate with the device GUI and evaluate device safety features like Q&A watchdog

Typical applications

  • Satellite radar, Shor and medium range corner radar, Ultra-shortrange radar, Long range front radar
