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 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 5µA from the battery when not

charging. A low-side current-sense resistor allows the

b a tte ry c ha rg e c urre nt to b e re g ula te d while s till

supplying power to the battery’s load.

♦ Fast Charge NiMH or NiCd Batteries

♦ Voltage Slope, Temperature, and Timer

Fast-Charge Cutoff

♦ Charge 1 to 16 Series Cells

♦ Supply Battery’s 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 or Switch-Mode Power Control

♦ 5µA Max Drain on Battery when Not Charging

♦ 5V Shunt Regulator Powers External Logic

The MAX712 terminates fast charge by detecting zero

volta g e s lop e , while the MAX713 us e s a ne g a tive

voltage-slope detection scheme. Both parts come in 16-

pin DIP and SO packages. An external power PNP tran-

s is tor, b loc king d iod e , thre e re s is tors , a nd thre e

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.
