DRV8801RTYR, DMOS полномостовой драйвер двигателя, шаговый и щеточный DC, 2 выхода, 8В — 36В питание, 2.8А выход

The DRV8801RTYR is a brushed DC Motor Driver with current sense (PH/EN Ctrl). It provides a versatile motor driver solution with a variety of capabilities. The device 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 current up to ±2.8A and operating voltages 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.
