General Description
The MIC79050 is a simple single-cell lithium-ion battery charger. It includes an on-chip pass transistor for high precision charging. Featuring ultrahigh precision (+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.

Features
• High accuracy charge voltage: ±0.75% over -5°C to + 60°C (Li-ion charging temperature range)
• “Zero” off-mode current
• 10µA reverse leakage
• Ultralow 380mV dropout at 500mA
• Wide input voltage range
• Logic controlled enable input (8-pin devices only)
• Thermal shutdown and current limit protection
• Power MSOP-8, Power SOIC-8, and SOT-223
• Pulse charging capability

Applications
• Li-ion battery charger
• Celluar phones
• Palmtop computers
• PDAs
• Self charging battery packs
