DRV8876PWPR Description

DRV8876PWPR is a flexible motor driver for a wide variety of applications.The device integrates an N-channel H-bridge, charge pump regulator,current sensing and regulation, current proportional output, and protection circuitry. The charge pump improves efficiency by allowing for both high-side and low-side N-channels MOSFETs and 100% duty cycle support. DRV8876PWPR comes in pin-to-pin, scalable RDS(on) options to support different loads with minimal design changes.
Integrated current sensing allows for the driver to regulate the motor current during start up and high load events. A current limit can beset with an adjustable external voltage reference. Additionally, it provides an output current proportional to the motor load current. This can be used to detect motor stall or change in load conditions. The integrated current sensing uses an internal current mirror architecture,removing the need for a large power shunt resistor, saving board area and reducing system cost.
