‘D1 = 1, D0 = 0 channel 2 input, monitors input voltage of battery regulator ‘D1 = 1, D0 =1 channel 3 input, monitors battery charging current

‘Note: channel 0 is usually jumpered to CN3 term2 for monitoring battery voltage

‘Note: channel 2 tracks main power input when greater than battery voltage

‘Note: channel 2 approx. 0.6V less than battery voltage when main input less than battery voltage.

Main Loop

Init:

12-bit ADC conversion result

16-bit timer

Peak voltage detected

Single-ended, two-channel mode. Output 0s after data transfer is complete. Maximum current level (50 = 1A 75 = 1.5A) Maximum battery pack charge voltage Maximum battery charging time (10,800 = 3hr.)

AD convertor points for –deltaV (74pt/V IE 0.2V=18pts).

Trickle Charge Level (12 =.25A) See below: Minimum battery voltage (10V)
