Description
The MIC79050 is a single-cell lithium-ion battery charger with an on-chip pass transistor for high-precision charging. It offers ultrahigh precision ( 0.75% over the Li-ion battery charging temperature range) and "zero" off-mode current, providing a cost-effective solution for charging lithium-ion batteries.
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 packages
Pulse charging capability
Applications
Li-ion battery charger
Cellular phones
Palmtop computers
PDAs
Self-charging battery packs
