CAT3211
CAT3211 is I2C Programmable Haptic Driver manufactured by onsemi.
I2C Programmable Haptic Driver for Rotary (ERM) DC Motors
Description 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).
H- TRIG triggers a haptic sequence where Forward, Coast, Reverse and Recovery time durations are controlled. All four timer durations are configured via I2C interface registers.
The LDO output voltage supplying the H- Bridge can be programmed from 2.0 V to 5.0 V or shorted to VIN (using LDOH...
