This haptic driver reference design for LRA and ERM motors helps eliminate the design complexities of haptic motor control with features like reduced solution size, high efficiency output drive, closed-loop motor control, quick device startup and auto-resonance frequency tracking. This reference design board can be used for developing, testing and demonstrating motor-based haptic effects for systems with capacitive touch buttons and other interfaces. It also provides an easy way to compare ERM and LRA haptic effects.
