Overview
The DRV8662RGPR is a fully integrated piezo haptic driver manufactured by Texas Instruments, designed for tactile feedback applications. It operates on a supply voltage range of 3V to 5.5V and delivers an output load voltage between 20V and 200V. The device features a differential output configuration with a maximum output current of 75mA. It supports analog and PWM interfaces and utilizes power MOSFET technology. Packaged in a 20-QFN (4x4) surface-mount format, it functions within a junction temperature range of -40°C to +150°C.
Feature Summary
- Fully integrated control and power stage for piezo actuators
- Supports both analog and PWM input interfaces
- Differential output configuration for enhanced drive capability
Applications
- Haptic feedback systems in mobile devices
- Piezo actuator drivers in consumer electronics
- Tactile response modules in automotive interfaces
Procurement Notes
Verify the specific package variant against the datasheet, as the DRV8662 family includes different tape-and-reel options such as RGPT. Confirm that the 20-QFN form factor matches the target PCB footprint. Ensure the application environment remains within the specified -40°C to +150°C junction temperature limits to maintain operational reliability and longevity.
Selection Notes
Select this component when a compact solution for driving piezoelectric haptic elements is required. It is suitable for designs needing a wide output voltage swing up to 200V from a low-voltage supply. Consider the 75mA current limit and differential output topology when sizing the external piezo actuator. Verify compatibility with the system's control interface, whether analog or PWM.
Part Context
This part belongs to the DRV8662 series of haptic drivers from Texas Instruments. It is specifically engineered for piezo actuator applications, distinguishing it from standard motor drivers. The RGPR suffix indicates the reel packaging format, which is standard for high-volume surface-mount assembly processes in electronic manufacturing.
Replacement Considerations
The DRV8662RGPT is a parameter-equivalent alternative within the same product line. Both parts share identical electrical specifications and functionality, differing primarily in their shipping packaging configuration. No functional changes are associated with switching between these specific suffixes.
