Hi everyone. Can you help me with this circuit I am working on, please?. (Image 1) It consists of a TP4056 charger/controller connected to a 3.7v/1.4Ah Li-Ion battery to supply a low battery indicator and a load (3 leds + 2 fans) through a MT3608 Step Up to raise voltage from 3.7v to 9v. When the TP4056 is charging the battery through the USB port, the load is disconnected by the P-Mosfet. PROBLEM: Voltage drops significantly when the load is connected. Test1: Circuit without Debouncing/Load connected: Voltage drops from 3.68v to 3.46v (image 2). Low Battery Indicator: Blink
Hi guys, I would like to ask your help. I would like to make an electronic circuit where it can detect the fan failure and indicates it with the light.

Thank you guys for your cooperation. I really appreciate it.
