PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The DRV8411 is a dual H-bridge motor driver that can drive one or two DC brush motors, one stepper motor, solenoids, or other inductive loads. The tripler charge pump allows the device to operate down to 1.65V to accommodate 1.8V supply rails and low-battery conditions. The charge pump integrates all capacitors and allows for 100% duty cycle operation. The inputs and outputs can be paralleled to drive high current brush DC motors with half the RDS(on).
The device implements current regulation by comparing an internal refernce voltage to the voltage on the xISEN pins, which is proportional to motor current through an external sense resistor. The ability to limit current can significantly reduce large currents during motor startup and stall conditions.
A low-power sleep mode achieves ultra-low quiescent current draw by shutting down most of the internal circuitry. Internal protection features include undervoltage, overcurrent, and overtemperature.
The DRV8411 is part of a family of devices which come in pin-to-pin, scalable RDS(ON) options to support various loads with minimal design changes. See Section 4 for information on the devices in this family. View our full portfolio of brushed motor drivers on ti.com.
