3 Description

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 DRV2510-Q1 device provides protection functions such as undervoltage lockout, over-current protection and over-temperature protection.

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.
