Texas Instruments TPS929160-Q1 16-Channel LED Driver

Texas Instruments TPS929160-Q1 16-Channel LED Driver comes with a FlexWire interface to address increasing requirements for individual control of each LED string. Each device channel can support analog dimming and pulse-width-modulation (PWM) dimming, configured through its FlexWire serial interface. The internal electrically erasable programmable read-only memory (EEPROM) allows users to configure the device during communication loss to fulfill system-level safety requirements.

The Texas Instruments TPS929160-Q1 controls the 8-bit output current and 12-bit PWM duty cycles. The device meets multiple regulation requirements with LED open-circuit, short-to-ground, and single LED short-circuit diagnostics. A configurable watchdog also automatically sets FAIL-SAFE states when the MCU connection is lost, and with programmable EEPROM, TPS929160-Q1 can flexibly be set for different application scenarios.
