onsemi CAT3211
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. 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 register).| Part No. | CAT3211 |

DESCRIPTION
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. This allows the motor to be safely overdriven for short durations, greatly increasing the user experience. Driving VIB_EN high sets the H−Bridge 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.FEATURES
