MAX712CPE+ Datasheet PDF - Maxim Integrated

●The MAX712CPE+ is a NiCd/NiMH battery Fast-charge Controller 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. This 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.

● Voltage slope, temperature and timer fast-charge cut-off

● Supply battery load while charging (linear mode)

● Fast charge from C/4 to 4C rate

● C/16 Trickle-charge rate

● Automatically switch from fast to trickle charge

● Linear mode power control
