The DRV8218 is an integrated H-bridge motor driver featuring four N-Channel power FETs, a charge pump regulator, and built-in protection circuitry. A tripler charge pump architecture enables operation down to 1.8V, maintaining stable RDS(on) even at low battery voltages. All capacitors are integrated, minimizing PCB footprint and enabling 100% duty cycle operation.

The device supports three control interface modes - PWM (IN1/IN2), phase/enable (PH/EN), and independent half-bridge - as well as a parallel half-bridge mode. Each interface includes a low-power sleep mode that reduces quiescent current to under 120nA by shutting down most internal circuitry.

Output current reaches up to 8A peak, with a logic supply range of 1.8V to 5.5V and a motor supply range of 1.8V to 11V. Built-in protection includes undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD). The DRV8218 is part of a pin-to-pin compatible family with scalable RDS(on) and supply voltage options.
