Philips shaver nickel metal hydride to lithium battery

Overview

This circuit includes a 3.7v to 1.2V DC-DC circuit, a 4056 charge management IC, a lithium battery overcharge and overdischarge protection IC, a type-c charging interface, and a touch sensor to prevent accidental startup. For detailed applications, please search on the Digital Home Forum ( Philips P2015 shaver has been redesigned and replaced with lithium battery, and a touch sensor has been installed to improve false triggering of the battery)

It is suitable for replacing the lithium battery of old razors. You no longer have to worry about the small capacity and memory effect of nickel-metal hydride batteries. In the schematic diagram, R12 is the pull-down resistor of the dc-dc enable end. The pcb file has not been added yet. Please Notice
