Description

The U2352B bipolar circuit is a PWM device for controlling logic level Power MOSFETs and IGBTs. U2352B 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.
