U2352B
PWM Power Control for DC Loads
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鈥檚 on-state resistance, R
DS(on)
, or via a
shunt resistor.
Special Features
