The DRV8812 provides an integrated motor driver solution for printers, scanners, and other automated equipment applications. The device has two H-bridge drivers, and can drive a bipolar stepper motor or two DC motors. The output driver block for each consists of N-channel power MOSFET’s configured as full H-bridges to drive the motor windings. The DRV8812 is capable of driving up to 1.6-A of output current (with proper heatsinking, at 24 V and 25°C).
A simple parallel digital control interface is compatible with industry-standard devices. Decay mode is programmable.
Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature.
The DRV8812 is available in a 28-pin HTSSOP package with PowerPAD™ and in a 28-pin QFN package PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
