Overview

MITSUMI Lithium-Ion Battery Charge Control IC MM3358 Lithium-Ion Battery Charge Control IC Monolithic IC MM3358 Outline This IC is a linear charge control IC for 1-cell Lithium-Ion and lithium-polymer batteries.

It incorporates a power MOSFET and a reverse-current block circuit for easy implementation of charge control of Lithium-Ion and Lithium-polymer batteries without an external sense resistor and a reverseblocking diode.

The chip temperature detection function can limit the temperature rise in the IC during high power charging and the temperature detection function enables the temperature for charge to be controled.

Key Features

1. BAT Regulation Voltage 4.2V±30mV(±0.7%) 2. Fast Charge Current 558mA ± 5%( RICHG = 2.32kΩ) 3. The external resistor enables trickle/fast-charge current/charge completion current to be set (Maximum charge current : 1.5A). 4. A charge timer is embedded in this IC. The external resistor enables the charge t.
