MM3458
MM3458 is Lithium-ion battery charge controller manufactured by MITSUMI.
Features
1. BAT Regulation Voltage 4.2V±30m V(0.7%)
2. Fast Charge Current
558m A±5%
3. Preliminary current, high-speed charging current, charging pletion current can be set using external resistors (maximum charging current is 1.5 A) .
4. A battery temperature detection function is provided via a thermistor, and so the charging voltage and current can be controlled according to the battery temperature.
5. Chip temperature detection enables control of IC temperature rises at high-power charging. The battery can...
