PIEZO HAPTIC DRIVER, W BOOST CONV, 20QFN.
The DRV8662RGPT is a Piezo Haptic Driver with integrated boost converter, integrated power diode and integrated fully-differential amplifier. This versatile device is capable of driving both high-voltage and low-voltage piezo haptic actuators. The input signal can be either differential or single-ended. The boost voltage is set using two external resistors and the boost current limit is programmable via the REXT resistor. The boost converter architecture will not allow the demand on the supply current to exceed the limit set by the REXT resistor, therefore, the DRV8662 is well-suited for portable applications. This feature also allows the user to optimize the driver circuit for a given inductor based on the desired performance requirements. A typical start-up time of 1.5ms makes the driver an ideal piezo driver for fast haptic responses. Thermal overload protection prevents the device from being damaged when over driven.
