【经验】PWM充电器SGM41526用于扫地机器人发热异常问题分析
SGM41526是一款4A同步1.6MHz PWM充电器，内部有循环电流限制，集成24V开关MOSFET，数字软启动，充电效率高达95.2%，30V绝对最大输入电压额定值，可调过压阈值，4.5V至22V输入工作电压范围，自动电源路径选择器（电池/适配器），动态电源管理（DPM）。有客户在扫地机器人上面用SGM41526做充电管理，样品测试芯片发热异常，本文将对该问题进行分析。
原理图如下
经过仔细检查，发现两处参数影响了IC发热
1， 芯片9脚，由于LED限流电阻太小，导致IC灌电流过大，影响发热
2， 芯片19脚，这个脚功能是用来驱动MOS的，直接接地，相当于芯片一直处于放电状态，不但影响发热，还影响功耗。
最终9脚外部电阻放大，19脚悬空，解决问题。
