1.1 Introduction

The DRV8218 is an H-bridge motor driver with PH/EN, PWM, and half-bridge control interfaces and a low power sleep mode.

The DRV8218 is an integrated H-bridge motor driver that supports a voltage range of 1.8 V to 11 V with up to 8 A peak current with four N-Channel power FETs, a charge pump regulator, and built-in protection circuitry. A tripler charge pump architecture enables operation down to 1.8 V, maintaining stable RDS(on) even at low battery voltages. All capacitors are integrated, minimizing PCB footprint and enabling 100% duty cycle operation. The DRV8218 includes integrated protection features such as undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD).

This document is provided with the DRV8218 evaluation modules (EVMs) as a supplement to the DRV8218 datasheet. This user's guide covers EVM hardware setup and operational instructions.
