Texas Instruments DRV8662 Piezo Haptic Driver with Integrated Boost Converter DRV8662RGPT

The DRV8662RGPT is a high-voltage piezo haptic driver designed for driving piezoelectric actuators in various applications, including mobile phones, tablets, and touch-enabled devices. It can drive capacitive loads up to 680 nF at 50 V peak-to-peak and features a differential output. The device integrates a boost converter that allows for adjustable boost voltage and current limit, eliminating the need for an external transformer. It operates over a supply voltage range of 3.3 V to 5.5 V and is compatible with 1.8 V digital pins. The DRV8662RGPT has a fast start-up time of 1.5 ms and includes thermal protection to prevent damage from overheating. The product is housed in a compact 4 mm vó 4 mm QFN package, making it suitable for space-constrained designs.
