The CXPR7883A 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.
