MM1292 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.
