Advantages: (1) As 2576 has an interior overcurrent and overtemperature-proof device, it can input constant voltage, constant current CC and overvoltage proof OVP together with 358, so as to achieve a reliable, safe and perfect charge solution of lithium cells. (2) EMI design of automobile charger is relatively easy for 2576 is a fixed 52-k PWM convertor. (3)Both 2576 and lm358 are made in high pressure and dual polar, so they are very firm. (4)This solution is usually used in automobile charger of 0.8A~1.5A. Disadvantages: (1) Its system is complex and costly. (2) CC and OVP control the 2576 EN by 358’s input, therefore, the charge current has a relatively large wave, and corresponding speed of CC and OVP is not prompt enough.
