usblipocharger's Introduction

USBLiPoCharger

LiPo / Li-Ion chargers based on MAX1555, MAX1551 and MCP73831.

Features:

  • home PCB manufacturing friendly
  • selectable USB/external DC power source - if you don't need USB, just chop off the connector and use DC pads
  • for MAX155X parts - charging current selectable by solder jumper
  • for MAX1555 and MCP73831 - charging and battery full indication LEDS; Note: MAX1555 charger indication relies on low mosfet gate threshold voltage - below (5V - Vfwdled), I've used 702 mosfets.
  • for MCP7383 - charging current selectable by two resistors

Licenced under CERN OPEN HARDWARE LICENCE v1.1
