The charging circuit of 12V Ni-MH battery pack designed by MAX713 chip is relatively simple and applicable. The whole charging process and status display are realized by MAX713 alone. The whole power management module is simple and reliable, but only because of the large number of battery packs and only linear mode. Therefore, there is a certain amount of heat generation for Q1 and Q2, but it has been improved by adding a heat sink. Now the circuit has been widely used in a portable measuring instrument in China, and the work is stable and reliable.
