MM1292C Datasheet (MITSUMI) - Protection of Lithium Ion Batteries (two cells in series)

MM1292C, Protection of Lithium Ion Batteries (two cells in series)

Pin No.

Pin Output Function Output pin for control of the charging control FET.

When voltage detected between VH-VL or VL-GND goes over overcharge detection voltage (VALM), the output PNP1 OC Output TR (open collector output) is switched ON, and charging is prohibited by activating the element (NPN-

MITSUMI Protection of Lithium Ion Batteries (two cells in series) MM1292 Protection of Lithium Ion Batteries (two cells in series) Monolithic IC MM1292 Outline This IC is for protecting a lithium ion battery from overcharging, excess discharging, and overcurrent.

If abnormalities occur during charging and excess voltage is applied, it has a function that turns off the external FET switch when voltage is applied to each battery beyond a specified time (overcharging detection).

It also has a fu
