Main features:
Programmable charge current: 600Ma
Charge mode: constant current, constant voltage, constant temperature
Charge status indicator: You can drive LED or microcontroller interface
Input power failure, automatically enter a low power sleep mode
Battery voltage is low, the automatic use of small current pre-charge mode
Agency Distribution: charging IC, DC-DC step-up IC, DC-DC step-down IC, LDO regulator IC
Thanks, Mike! Now we know exactly what it does (as we guessed)! I wonder how the charge current is "programmed"? i.e. can it be modified in an existing #11 camera to lower it's charge rate to give batteries a longer cycle life?
