TCPL01x Features

TCPL01x is an AEC-Q100 Grade 1 qualified RGB LED driver with LIN interface, designed for automotive dynamic interior RGB light and intelligent rear light. It features 32-bit Arm® Cortex®-M0 CPU core, 64KB flash and 4kB SRAM, a LIN transceiver supporting LIN auto-addressing. The integrated current sources can be controlled by a 16-bit PWM with a 48MHz clock. This enables PWM cycle frequencies up to 730Hz with 16-bit resolution. Each of the three drivers can be used to drive external loads up to 60mA. The integrated ADC can measure the forward voltage of LEDs differentially.
