Product Overview
The DRV8801 is a Texas Instruments DMOS full-bridge motor driver in the Power_Management category. Its output stage is a full H-bridge implemented with N-channel power MOSFETs, intended for driving a brushed DC motor, one winding of a stepper motor, or solenoids through a PHASE-ENABLE control interface.
The driver operates from an 8 V to 36 V supply range and supports ±2.8 A peak output current. It supports 100% PWM duty cycle operation, with PHASE and ENABLE inputs specified for applied PWM frequencies from 0 kHz to 100 kHz. Typical MOSFET on-resistance is listed as 0.4 Ω, with separate source and sink driver resistance values specified at 25°C and 125°C.
Package options include 16-pin WQFN 4.00 mm × 4.00 mm and 16-pin HTSSOP 5.00 mm × 4.40 mm. Thermal data includes junction-to-ambient, junction-to-board, and junction-to-case resistance values for both packages. Protection and reporting functions include nFAULT open-drain fault indication plus UVLO, overcurrent, short-to-supply, short-to-ground, overtemperature warning, and overtemperature shutdown functions.
