摘要: 本文介紹專為鋰離子電池組設(shè)計的充電控制器MAX745,該芯片采用雙環(huán)控制,PWM工作頻率為300kHz。采用該控制芯片的充電器,外圍元件少,充電電壓精度高,可對1-4只鋰離子電池組充電,并具有鋰離子電池組充電所需的全部功能。
敘詞:鋰離子電池組 充電控制器
Abstract: The MAX745 provides all functions necessary for charging Lithium-ion battery packs witch using two loops that working together control the voltage point and charging current. The number of cells is set from 1 to 4 by pin-strapping.
