Liquid Lens Driver

 

The HV892 liquid lens driver is a high voltage driver targeted for driving variable liquid lenses for various optical applications. The HV892 features an I2C interface, and is compatible with 40VRMS to 60VRMS lenses. The integrated charge pump boost generates the necessary high voltage with no external inductors or diodes.

Complimentary MOSFET Level Translator and Driver

 

The Complimentary FET Drivers use Microchip’s proprietary HVCMOS® technology to create a fully isolated driver for our Complimentary MOSFET products. They enable drive of MOSFETs for uni- or bidirectional switching, supporting isolation voltages up to 400V, with no external power supplies required.

High Side Current Monitor

 

The High Side Current Monitors transfer high-side current measurement voltages to a ground referenced output with a voltage gain. The measurement voltage typically originates at a current sense resistor which is located in a “high side” circuit, such as the positive supply line.

Fault Protection

 

High Voltage Fault Protection ICs are switches are designed to protect system output power supplies against over-current or short circuit conditions. In protection mode, they limit the load current. They are essentially normally closed switches with a foldback current capability, with a rated withstand voltage capability.
