MIC79050
Simple Lithium-Ion Battery Charger
Features General Description High-Accuracy Charge Voltage: В±0.75% over
–5°C to + 60°C (Li-ion charging temperature
range) Zero Off-Mode Current 10 ВµA Reverse Leakage Ultra-Low 380 mV Dropout at 500 mA Wide Input Voltage Range Logic-Controlled Enable Input (8-Lead Devices
Only) Thermal Shutdown and Current-Limit Protection Power MSOP-8, Power SOIC-8, and SOT-223
Packages Pulse Charging Capability 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
(В±0.75% over the Li-ion battery charging temperature
range) and “zero” off-mode current, the MIC79050
provides a very simple, cost effective solution for
charging lithium-ion battery. Applications Li-Ion Battery Charger
Cellular Phones
Palmtop Computers
PDAs
Self-Charging Battery Packs 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
