Microchip Technology HV56020 Dual 250V Haptic Drive Amp Array w/ Boost is a Multi-Chip Module (MCM) driver solution for haptic applications. The IC consists of three devices. Dual High Voltage Operational Amplifiers, DC-to-DC controller, and a power MOSFET. The Op Amps are designed to drive haptic (piezo) actuators at 225V with a 40mA minimum source/sink current.
