Description
General part information
MIC79050 Series
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.
