BQ24074: 關於 THERMAL REGULATION

Part Number: BQ24074
Other Parts Discussed in Thread: BQ28Z610, EV2400

hi Ti Teams,

目前有一設計案使用BQ24074進行充電設計，設計規格: 4.2V/1.5A/230mA cut-off, 另電池規格: 1S3P / 9090mAh 

目前遇到在充電狀況下Vbat = 3.2V ~ 4.2V  ( cc mode )時出現充電電流有中斷的狀況發生( 如附件使用EV2400 / BQ28Z610 Log ) 想確認

1. 線路設計上是否有超過規格的設定?

2.該現象是否為Charger IC 因本體過熱觸發 THERMAL REGULATION 

3.同上如是因過熱造成目前 LAYOUT 部分也有在Button面開背等方式進行散熱是否還有修改的地方
