MAX712/MAX713
NiCd/NiMH Battery Fast-Charge Controllers
General Description
The MAX712/MAX713 fast-charge Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCd) batteries from a DC source at least 1.
5V higher than the maximum battery voltage.
1 to 16 series cells can be charged at rates up to 4C.
A voltage-slope detecting analog-to-digital converter, timer, and temperature window comparator determine charge completion.
The MAX712/MAX713 are powered by the DC source via an on-board +5V shunt
regulator.
They draw a maximum of 5µA from the battery when not charging.
A low-side current-sense resistor allows the battery charge current to be regulated while still supplyi...
