CAT2300
CAT2300 is Current Monitor manufactured by onsemi.
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 m A.
CAT2300 provides logic level ON/OFF control of the power MOSFET and its own internal circuitry, reducing power consumption to virtually zero milliwatts.
CAT2300 operates over the full industrial temperature range of
- 40°C to +85°C.
