Rail Current Measurement IC
FP130A
General Description
The FP130A is a wide common mode range high side rail current measurement IC. It is suitable
for power systems like battery charger or switching power supply applications. It includes a differential
input amplifier and an NPN transistor with emitter output. With three external resistors, the rail current
signal can be easily converted into an amplified voltage signal at the IC output pin. Also, the gain can
be adjusted by changing the three external resistors values.
Features
Independent Power Supply Voltage: 2.7 to 28V
Wide Input Common-Mode Voltage: 2.7 to 28V
