TIDRV8874QPWPRQ1
Overview
The DRV8874QPWPRQ1 is an AEC-Q100 qualified N-channel H-bridge motor driver designed for automotive applications, supporting a wide supply range of 4.5V to 37V. It features integrated current sensing and regulation with a peak output current capability of 6A, eliminating the need for external sense resistors. This functional safety-capable device includes spread spectrum clocking to minimize electromagnetic interference (EMI) in sensitive vehicle environments.
Why Choose This Part
This driver integrates proportional current sensing (IPROPI), which reduces board space and BOM cost by removing the requirement for bulky external shunt resistors. It offers high flexibility with selectable control modes (PH/EN, PWM, Independent Half-Bridge) and adjustable current regulation via the IMODE pin. The AEC-Q100 qualification and robust protection suite including UVLO, OCP, and TSD ensure high reliability in harsh environments.
Applications
Key Specifications
Getting Started
To evaluate this driver, use the DRV8874-Q1EVM evaluation module which provides a hardware platform for testing various PMODE and IMODE configurations. Interface the logic inputs (supporting 1.8V to 5V) with a microcontroller PWM peripheral to control motor speed and direction. Ensure the thermal pad of the 16-HTSSOP package is properly soldered to a large PCB ground plane to manage heat dissipation at high current loads.
