Overview
The DRV8601DRBR is a single-supply haptic driver designed by Texas Instruments to drive DC motors (Eccentric Rotating Mass or ERM) and linear vibrators (Linear Resonant Actuators or LRA). This device is optimized for use in portable electronic devices such as mobile phones, tablets, and portable gaming consoles. It features a fast turn-on time of 100 µs, making it ideal for applications requiring quick and precise haptic feedback. The DRV8601DRBR operates within a wide supply voltage range of 2.5 V to 5.5 V, allowing for direct battery operation, and it has a low quiescent current of 1.7 mA, which is beneficial for power-sensitive applications.
