MCP73831 Microchip

images (1)

MCP73831 from company “Microchip”  is No .1 choice for many applications.

All in one MCP73831 ,persuade  by hight energy density, low weight, low self-discharge and for majority of applications ,also by their favorable shape (LI-PO).

If you use only a single cell and maximun charging curent of 500 mA is sufficient for you , then MCP73831 will meet all requirements for a quality and safe recharging solution. MCP73831 has integrated output FET transistor, current sensing and reverse discharge protection.

MCP73831 also contains a thermal regulation, which decreases output current in case of increased chip temperature (for example because of higher ambient temperature).
