DESCRIPTION
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) APPLICATIONS
