PWM Power Control for DC Loads
U2352B
Description
The U2352B bipolar circuit is a PWM device for control-
ling 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
D Pulse width control up to 50 kHz clock frequency
D Load current monitoring via the on-state resistance,
RDS(on), of the FET or via shunt resistor (optional)
D 100 mA push-pull output stage
D Voltage monitoring
D Temperature-compensated supply voltage limitation
D Chip temperature monitoring
Applications
D Battery-operated screwdrivers
D Battery-operated machine tools
D Halogen lamp controllers
D Dimmers
D Electronic fuses
D High-performance clock generators
