The DRV8800RTYT is a DMOS full-bridge Motor Driver contains a full H-bridge which can be used to drive a brushed DC motor, one winding of a stepper motor or other devices such as solenoids. A simple PHASE-ENABLE interface allows easy interfacing to controller circuits. The output stages use N-channel power MOSFETs configured as an H-bridge. The DRV880xis capable of peak output currents up to ±2.8A and operating voltage up to 36V. An internal charge pump generates the needed gate drive voltages. A low-power sleep mode is provided which shuts down internal circuitry to achieve a very low quiescent current draw. This sleep mode can be set using a dedicated nSLEEP pin. Internal protection functions are provided for under-voltage, charge pump fault, overcurrent, short-to-supply, short-to-ground and over-temperature. Fault conditions are indicated through the nFAULT pin.
