CAT3211
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 compact 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 regis...
