Description

The DRV887x family of devices are flexible motor drivers for awide variety ofapplications.The devices integrate an N-channel H-bridge, charge pump regulator,current sensing and regulation, currentproportional output, and protection circuitry. The charge pump improves efficiency byallowing for both high-side and low-side N-channels MOSFETs and 100% duty cycle support. The familyof devices come in pin-to-pin, scalable RDS(on) options to support differentloads with minimal design changes.

Integrated current sensing allows for thedriver to regulate the motor current during start up and high load events. A current limit can beset with an adjustable external voltage reference. Additionally, the devices provide an outputcurrent proportional to the motor load current. This can be used to detect motor stall or change inload 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 systemcost.

A low-power sleep mode is provided to achieve ultra-low quiescent current draw byshutting down most of the internal circuitry. Internal protection features are provided for supplyundervoltage lockout (UVLO), charge pump undervoltage (CPUV), output overcurrent (OCP), and deviceovertemperature (TSD). Fault conditions are indicated on nFAULT.
