MM3635

MITSUMI Lithium-ion battery charge control IC MM3635 Lithium-ion battery charge control IC Monolithic IC MM3635 Outline This IC is a linear charge control IC for low capacity battery. Charging from 0V of battery voltage is available, so this IC is optimum for product used low-capacity battery. Charge control voltage can be set according to a battery to be used. (4.2 or 4.05V) Features 1. BAT Regulation Voltage 4.2V±30mV(0.7%) / 4.05V±50mV (Setting by CVSEL pin) 2. Fast Charge Current 15mA±1.8mA RICHG=74.2k 3. Charging from 0V of battery voltage. 4. Trickle-charge current, Fast-charge current, Charge completion current can be set using external resistors(maximum charging current is 0.7 A). 5. Battery temperature detection function is provided via a thermistor, and so the charging ON/OFF can be controlled according to the battery temperature. 6. Chip temperature detection enables control of IC temperature rises at high-power charging. The battery can therefore be charged...
