HV56020-V/KXX - 250V Dual High Voltage Op Amp with Step-Up Converter and Power MOSFET

HV56020-V/KXX - Product Description:

HV56020-V/KXX is a dual amplifier with integrated boost for driving piezo actuators for haptic applications. The HV56020 comes with 3 functions, specifically, dual 250V operational amplifiers, a boost controller, and a power MOSFET. The opamps are designed to drive haptic (piezo) actuators at 225V with 40 mA minimum source/sink current. The boost controller and power MOSFET along with an external transformer generate the voltage supply for the HV opamps using a non-Isolated flyback configuration.

HV56020-V/KXX - Product Features:

3-Bit DAC for Boost Output Control (Minimize Pdiss vs. Drive Waveform)

Integrated FET (Vdss,Max 60V, Rds,on 10mO Max, 25°C)

Integrated Protection Features: OVP, UVP, OCP

Stand-By Mode (Min Current Mode)

Temperature Sensor

Power-On Reset

24 MHz SPI Interface

43-Ld. 7mm x 7mm VQFN, 0.9mm Thick
