Overview
The HV56020T-V/KXX is a Multi-Chip Module (MCM) driver solution designed for haptic applications, integrating dual high-voltage operational amplifiers, a DC-to-DC step-up converter controller, and a power MOSFET. The op amps drive piezo actuators up to +225V with a minimum peak output sink/source current of 40 mA and a -3 dB bandwidth of 124 Hz at 0.22 µF load. The integrated DC-to-DC controller accepts a single input voltage supply (VIN) ranging from 2.7V to 5.5V and generates the required high-voltage supply using a non-isolated flyback configuration. It includes overvoltage, undervoltage, and short circuit protection features.
Feature Summary
- Dual high-voltage operational amplifiers capable of driving loads up to +225V with 40 mA minimum peak source/sink current
- Integrated DC-to-DC step-up converter controller supporting a wide input voltage range of 2.7V to 5.5V
- Built-in power MOSFET with 60V breakdown voltage and low on-resistance for efficient flyback operation
- Comprehensive protection mechanisms including overvoltage, undervoltage, short circuit detection, and temperature sensing
Applications
- Haptic Drivers
- Power Amplifiers
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'V' grade corresponds to the extended operating temperature range of 0°C to +125°C. Ensure the 'KXX' designation matches the required RoHS compliance and lead finish specifications for your assembly process. Cross-reference the datasheet revision DS20006335A for the most accurate electrical characteristics.
Selection Notes
Select this component when designing systems requiring integrated high-voltage generation and amplification for piezoelectric actuators. The internal charge pump and flyback controller simplify the design by eliminating external high-voltage generation components. Consider the fixed 75 V/V gain and 124 Hz bandwidth limitations when determining suitability for specific actuator frequencies and signal requirements.
Part Context
This device belongs to Microchip's HV5602x family of multi-chip module drivers. It is specifically engineered to replace discrete high-voltage amplifier and boost converter solutions in compact form factors. The integration reduces board space and simplifies layout compared to separate high-voltage op amp and DC-DC controller implementations.
Replacement Considerations
HV56022 serves as a related device within the same family, offering dual high-voltage operational amplifiers without the integrated boost converter and MOSFET.
