Hi
1. for schematic: To add one bulk cap in USB_VCC line, ex: 22uF
2. After checking datasheet, I think this part should not have safety timer embedded.
3. if no safety timer then there is no reset concern
My question is where did you get information that this part has safety timer design? Maybe I can also help to double check.
Thanks
Hi Sir,
Another question need to yor reply as below:
1) I have add U48 N-MOS to control the TS pin. The signal CHARGER_STOP is come from GPIO. When i wnat to stop charge, the signal from GPIO will be pulled high and the U48 will be turned ON and TS pin will be pulled low. Is there any question to this application?
Hi,
This TS is just input pin and should be high impedance. so it is no problem with this external circuit.
But pull TS pin down will slightly increase power consumption from LDO pin.
Thanks
