SLOS709B – JUNE 2011 – REVISED DECEMBER 2014 DRV8662 Piezo Haptic Driver with Integrated Boost Converter
1 Features 3 Description The DRV8662 is a single-chip piezo haptic driver with
integrated 105 V boost switch, integrated power
diode, and integrated fully-differential amplifier. This
versatile device is capable of driving both highvoltage and low-voltage piezo haptic actuators. The
input signal can be either differential or single-ended.
The DRV8662 supports four GPIO-controlled gains:
28.8 dB, 34.8 dB, 38.4 dB, and 40.7 dB. 1 High-Voltage Piezo Haptic Driver
