3 Description
The DRV8802 provides an integrated motor driver
solution for printers, scanners, and other automated
equipment 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 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 is available in a 28-pin HTSSOP
package with PowerPAD™ (Eco-friendly: RoHS & no
Sb/Br).
