The DRV8840 provides an integrated motor driver solution for printers, scanners, and other automated
equipment applications. The device has one H-bridge driver, and is intended to drive one DC motor. The output
driver block for each consists of N-channel power MOSFET’s configured as full H-bridges to drive the motor
windings. The DRV8840 can supply up to 5-A peak or 3.5-A 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 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.
TheDRV8840 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
