产品概述

The MCP73837-FCI/UN is a highly integrated full-featured linear Li-ion Battery Charger with both USB and AC-adapter inputs. Automatic power source selection simplifies the design of battery chargers for applications that are powered from either an USB port or an AC adapter. For USB-powered systems, the MCP73837 specifically adheres to the current limits governed by the USB application. Also includes safety features such as cell temperature monitoring, on-chip thermal regulation and safety timers. The MCP73837 automatically selects the USB-port or AC-adapter as the power source for the system. For the USB-port powered systems, the MCP73837 specifically adheres to the current limits governed by the USB specification. The host microcontroller can select from two preset maximum charge current rates of 100mA (low power USB-port) or 500mA (high power USB-port).
