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
