DRV2510-Q1
SLOS919A – JUNE 2016 – REVISED JUNE 2016
7.1 Overview
The DRV2510-Q1 device is a high current haptic driver specifically designed for inductive loads, such as
solenoids and voice coils.
The output stage consists of a full H-bridge capable of delivering 3 A of peak current.
The design uses an ultra-efficient switching output technology developed by Texas Instruments, but with features
added for the automotive industry. The DRV2510-Q1 device provides protection functions such as undervoltage
lockout, over-current protection and over-temperature protection. This technology allows for reduced power
consumption, reduced heat, and reduced peak currents in the electrical system.
The DRV2510-Q1 device is automotive qualified. The integrated load-dump protection reduces external voltage
clamp cost and size, and the onboard load diagnostics report the status of the actuator through the digital
interface.
