Description

The U2352B bipolar circuit is a PWM device for controlling logic level Power MOSFETs and IGBTs. It allows simple power control for dc loads. Integrated load current monitoring with adjustable switch-off threshold also gives the option of measuring the load current via the MOS transistor’s on-state resistance, RDS(on), or via a shunt resistor.

Special Features

Pulse width control up to 50 kHz clock frequency

Load current monitoring via the on-state resistance, RDS(on), of the FET or via shunt resistor (optional)

100 mA push-pull output stage

Voltage monitoring

Temperature-compensated supply voltage limitation

Chip temperature monitoring

Applications

Battery-operated screwdrivers

Battery-operated machine tools

Halogen lamp controllers

Dimmers

Electronic fuses

High-performance clock generators
