Product Details

TPS929240QDCPRQ1 is Texas Instruments' 24-channel automotive high-side LED and OLED driver in a 38-pin HTSSOP package, with independently controlled outputs for pixel-style lighting.

Each channel can deliver up to 100 mA and has 12-bit PWM dimming, so a lamp controller can animate many segments without assigning a discrete driver to every LED group.

The FlexWire interface uses a CAN physical layer for off-board communication between lighting boards, addressing the noise and wiring constraints of distributed exterior lamps.

Programmable output current, phase-shifted PWM and the device's EEPROM settings let one hardware platform serve different brightness maps while retaining selected defaults at startup.

Open and short LED diagnostics, interface CRC and a watchdog-triggered fail-safe state give the host a defined response when a channel or communication link fails.
