TPS929240-Q1 evaluation module for 24-channel automotive LED driver

Overview

TopologyOther Topology

Description

The TPS929240-Q1 evaluation module (EVM) helps designers evaluate the operation and performance of TPS929240-Q1, a 12-channel 40-V highside LED driver with FlexLED™ interface to individually control output current and PWM dutycycle for automotive lighting applications. It also has LED open-circuit, short-to-ground, and single-LED short-circuit diagbostics. It supports entering pre-defined fail-safe states automatically when MCU connection is lost or without MCU control.

Features

  • 24-channel individual programmable precision highside constant current output
  • Up to 1-MHz clock frequency FlexLED™ serial interface
  • Progarmmable fail-safe mechanism with EEPROM
  • LED open-circuit, short-circuit and single-led short circuit diagnostic with built-in auto-ADC

Typical applications

  • Automotive exterior rear light, Automotive exterior headlight, Automotive interior ambient light, Automotive cluster display
