General Description The MAX712 MAX713 fast charge Nickel Metal Hydride NiMH and Nickel Cadmium NiCd batteries from a DC source at least 5V higher than the maximum battery voltage to series cells can be charged at rates up to 4C A voltage slope detecting analog to digital convert er 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 5m A 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 The MAX712 terminates fast charge by detecting zero voltage slope while the MAX713 uses a negative voltage slope detection scheme Both parts come in pin DIP and SO packages An external power PNP tran sistor blocking diode three resistors and three capacitors are the only required external components For high power charging requirements the MAX712 MAX713 can be configured as a switch mode battery charger that minimizes power dissipation Two evaluation kits are available: Order the MAX712EVKIT DIP for quick evaluation of the linear charger and the MAX713EVKIT SO to evaluate the switch mode charger
