CAT2300 Current Monitor for 0.9 V 1.5 V Bus Description CAT2300 is a controller for MOSFET current monitoring in high-side switch applications. CAT2300 provides current mirroring and ON/OFF control for MOSFETs. Exact control and matching of the Sense output of the MOSFET with the Kelvin voltage insures accurate current monitoring over a couple of decades of current. CAT2300 is the single chip alternative to discrete circuits for monitoring and controlling 0.9 V − 1.5 V power busses. When teamed with a MOSFET, CAT2300 will track currents up to 25 A and resolve currents below 100 mA. CAT2300 provides logic level ON/OFF control of the power MOSFET and its own internal circuitry, reducing power consumption to virtually zero milliwatts.
