PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The DRV8411A device is a dual H-bridge motor driver for driving two brushed DC motors or one stepper motor from a 1.65V to 11V supply rail. The integrated current regulation feature limits motor current to a predefined maximum based on the VREF and xIPROPI settings. The xIPROPI signal can provide current feedback to a microcontroller during both the drive and brake/slow-decay states of the H-bridge.
Two logic inputs control each H-bridge, which consists of four N-channel MOSFETs that have a typical RDS(ON) of 400mΩ (including one high-side and one low-side FET). A single power input, VM, serves as both device power and the motor winding bias voltage. The integrated charge pump of the device boosts VM internally and fully enhances the high-side FETs. Motor speed can be controlled with pulse-width modulation, at frequencies between 0 to 100kHz. The device enters a low-power sleep mode by bringing all four inputs low.
A variety of integrated protection features protect the device in the case of a system fault. These include undervoltage lockout (UVLO), overcurrent protection (OCP), and overtemperature shutdown (TSD).
