MIC79050中文资料Simple Lithium-Ion Battery Charger数据手册Microchip规格书

描述 Description

The MIC79050 is a simple single-cell Lithium-Ion battery charger. It includes an on-chip pass transistor for high precision charging. Featuring ultra-high precision (±0.75% over the Li-Ion battery charging temperature range) and zero off-mode current state, the MIC79050 provides a very simple, cost effective solution for charging Lithium-Ion battery.Other features of the MIC79050 include current limit and thermal shutdown protection. In the event the input voltage to the charger is disconnected, the MIC79050 also provides minimal reverse-current and reversed-battery protection.The MIC79050 is a fixed 4.2V device and comes in the thermally-enhanced MSOP-8, SOIC-8, and SOT-223 packages. The 8-pin versions also come equipped with enable and feedback inputs. All versions are specified over the temperature range of -40°C to +125°C.
