The DRV8840 is an integrated motor driver solution for printers, scanners, and other automated equipment applications. The device integrates a single NMOS H-bridge, charge pump, current sense, current regulation, and device protection circuitry. The DRV8828 can be powered from a single voltage supply from 8.2 V to 45 V, and is capable of providing a continuous output current up to 5 A.

A simple PHASE/ENBL interface allows for easy interfacing to an external controller. A 5 bit current control scheme allows for up to 32 discrete current levels. The current regulation method is adjustable between slow and fast decay.

Integrated protection circuits allows the device to monitor and protect against overcurrent, undervoltage, and overtemperature faults which are all reported through a fault indication pin (nFAULT). A low power sleep mode is integrated which allows the system to lower power consumption when not driving the motor.
