MAX713CSE+.

The MAX713CSE+ is a NiCd/NiMH battery Fast-charge Controller. The 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 analogue-to-digital converter, timer and temperature window comparator determine charge completion. The MAX713 is 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 supplying power to the battery's load.
