DRV8662RGPT

Overview

The DRV8662RGPT is a piezo haptic driver from Texas Instruments, housed in a 20-QFN (4x4 mm) package. It operates on a supply voltage of 3 V to 5.5 V and delivers an output current of 75 mA. The device supports load voltages between 20 V and 200 V, with a junction temperature range of -40°C to +150°C. It features analog and PWM interfaces for full-integrated control and power stages.

Feature Summary

• Integrates a boost converter for high-voltage piezo actuator driving
• Provides differential full-bridge output configuration
• Supports both analog and pulse-width modulation input signals

Applications

• Piezo haptic feedback systems
• Mobile device vibration modules
• Wearable technology actuators

Procurement Notes

Verify the specific suffix RGPT against the official datasheet to confirm the tape-and-reel packaging format. Ensure compatibility with the required QFN-20 footprint and thermal pad soldering specifications during assembly planning.

Selection Notes

Select this component when a compact solution for piezo haptics is required without external boost circuitry. Consider the 75 mA output limit and the wide operating temperature range for industrial or automotive environments compared to lower-rated alternatives.

Part Context

This part belongs to the DRV8662 family of piezo haptic drivers. It serves as a specialized motor controller designed specifically for resonant piezoelectric actuators, distinguishing it from standard DC or stepper motor drivers within the broader Texas Instruments portfolio.

Replacement Considerations

The DRV8662RGPR is a parameter-equivalent alternative available in cut-tape packaging.
