Outline
This IC was developed for charge/discharge current - voltage conversion for secondary batteries (MiMH, Liion) in notebook PCs, PDA, etc.
The IC can operate from a 3V power supply, and detection power supply can detect current up to 24V. It monitors charge and discharge current on notebook PC batteries, inputs the data to the CPU and manages remaining battery power, etc.

FEATUREs
1. CMRR f = 1kHz 80dB typ.
2. PSRR f = 1kHz 80dB typ.
3. Power supply voltage 3 ~ 24V
4. Consumption current 150µA typ.
5. Voltage gain switchable between 50 and 100
6. Input equivalent offset voltage ±0.5mV
7. Current detection high/low switching

APPLICATIONs
(1) Notebook PCs
(2) PDA
