CAT3211
I2C Programmable Haptic
Driver for Rotary (ERM) DC
Motors
Description
The CAT3211 is an HBridge 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).
HTRIG 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 HBridge can be
programmed from 2.0 V to 5.0 V or shorted to VIN (using LDOH
register). This allows the motor to be safely overdriven for short
durations, greatly increasing the user experience.
Driving VIB_EN high sets the HBridge to forward direction and
LDO voltage to a predefined vibrator setting (using LDOV register).
The motor can be continuously and safely driven at low voltages in
vibrator mode.
The device is fully protected against POS, NEG and REG short and
over current conditions. Thermal shutdown protection prevents
damage to the device and system during over temperature junction
conditions.
UQFN12 1.7 x 2 mm package is ideal for space constrained
applications.
