HV56020 Dual High Voltage Op Amp with Step-Up Converter and Power MOSFET Features Description Dual High Voltage Operational Amplifiers The HV56020 is a Multi-Chip Module (MCM) driver solution designed for Haptic Applications. The IC - Up to +225V consists of three devices: (1) Dual High Voltage - 40 mA Minimum Peak Output Sink/Source Operational Amplifiers, (2) a DC-to-DC Controller, and Current (3) a Power MOSFET. The Op Amps are designed to - Output Voltage Comparators for Short Circuit drive haptic (piezo) actuators at 225V with 40mA Detection minimum source/sink current. The DC-to-DC - 124 Hz, 3 dB Bandwidth with 0.22 F Load Controller and the power MOSFET along with an DC-to-DC Step-Up Converter external transformer generate the voltage supply for the High Voltage Op Amps using a Non-Isolated - Single Input Voltage Supply V : 2.7V to 5.5V IN Flyback configuration. - Overvoltage Protection The HV56020 includes ample protection circuitry: - Undervoltage Protection Over/Undervoltage Protection, Output Short Circuit - Short Circuit Protection Protection (DC-to-DC), Temperature Sensor and - Low Current Standby Mode Output Voltage Comparators for load Short Circuit - Temperature Sensor Detection. - Power-ON Reset - 24 MHz SPI Interface Package Type Power MOSFET 7 mm x 7 mm 43-Lead VQFN -60V BV DSS -10m On Resistance TOP VIEW SEE THROUGH Applications 43 42 41 40 39 38 37 36 35 34 33 32 Haptic Drivers Power Amplifiers 1 HVGND D 31 D 30 2 CCP2+ Related Devices D 3 CPP2- HV56022 Dual High Voltage Operational 4 CPP1+ Pad 2 D 29 HVGND Amplifiers 5 CPP1- 6 VIN HVGND 28 7 VLL 8 SCK HVOUT0 27 9 SDI HVGND Pad 1 HVGND 10 SDO VPP 26 11 SS 12 HVGND HVOUT1 25 13 14 15 16 17 18 19 20 21 22 23 24 See Table 3-1 for pin information. 2020 Microchip Technology Inc.
