battery charger control

This block provides the necessary signals to control the external circuits that perform the charger function. The

charging activities include battery pack wake up, precharge, fast charge, and battery temperature monitoring.

This block also provides two ADC inputs for general measurement purpose. The input voltage level is from 0

to 2 volts. This block also includes an oscillator generator circuit, which generates the clocks for the device. The

nominal frequency of the main clock is 500 kHz. It requires an external capacitor of 470 pF.

reference system

This block provides voltage reference and bias current for the internal circuitry.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
