8.1 Overview

DRV8210 is an integrated H-bridge driver with multiple control interface options: PWM (IN1/IN2) interface (DRL and DSG packages), PH/EN (DSG only), or half-bridge interface (DSG only). To reduce area and external components on a printed circuit board, the device integrates a charge pump regulator and its capacitors. In the DSG package, the separate motor (VM) and logic (VCC) supplies allow the motor supply voltage to drop to 0 V without significant impact to RDS(on) and without triggering UVLO as long as the VCC supply is stable. A timed auto-sleep mode reduces microcontroller GPIO connections by eliminating a disable/sleep pin and automatically putting the device into a low-power sleep mode when the inputs remain inactive for 1-2 ms.

The PWM interface is a standard 2-pin (IN1/IN2) motor drive interface. The PH/EN interface allows bi-directional PWM control using only one PWM resource from the controller. PWM and PH/EN interfaces can drive loads like brushed DC motors and bistable relays bidirectionally. Independent half-bridge mode allows for full control over each half-bridge. The half-bridges can independently control two loads with each channel acting as a high-side or low-side driver with half of the RDS(on) of full-bridge driving. Alternatively, half-bridge mode also allows the inputs and outputs to be connected together, or "paralleled," to drive a single load as a high-side or low-side driver with one-forth the RDS(on) of full-bridge driving.

The 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).
