3 Description
The DRV8802-Q1 device provides an integrated
motor driver solution for automotive applications. The
device has two H-bridge drivers, and is intended to
drive DC motors. The output driver block for each
consists of N-channel power MOSFET’s configured
as H-bridges to drive the motor windings. The
DRV8802-Q1 device can supply up to 1.6-A peak or
1.1-A RMS output current (with proper heatsinking at
24 V and 25°C) per H-bridge.
A simple parallel digital control interface is compatible
with industry-standard devices. Decay mode is
programmable to allow braking or coasting of the
motor when disabled.
Internal shutdown functions are provided for over
current protection, short circuit protection, under
voltage lockout and overtemperature.
The DRV8802-Q1 device is available in a 28-pin
HTSSOP package with PowerPAD™ (Eco-friendly:
RoHS & no Sb/Br).
