CAT3211 Overview
The CAT3211 is an H−Bridge motor driver IC that includes an I2C programmable haptic generator state machine, internal oscillator and adjustable LDO voltage regulator, all in one pact solution. Two operating modes are supported: haptic mode (triggered via H_TRIG pin or register) and vibrator mode (VIB_EN pin or register).
