FP120
RAIL CURRENT MEASUREMENT IC
GENERAL DESCRIPTION
The FP120 is a wide input supply and common mode voltage IC for the high side rail current
measurement of the power system such as battery charger or switching power supply applications
field. IC includes the differential input of amplifier and an NPN transistor emitter output; user could
adjusts any gain very easy from three external resistors and read the converting voltage by a simple
by a formula at IC output.
The FP120 uses the SOT-25 package operating in wide power supply and temperature range
