Описание

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).
