MITSUMI

3 cell Lithium-ion/Lithium-polymer battery protection IC MM3783 Series

(3) Temperature protection function

Temperature protection thresholds can be setting 3 value (two thresholds of high temperature, one threshold of low

temperature) by using a NTC thermistor.

Example of temperature protection setting

High temp protection :

Charge control

Detect : +50°C ±3°C, Release : +40°C ±3°C

Discharge control

Detect : +70°C ±3°C, Release : +60°C ±3°C

Lot temp protection :

Charge/Discharge control

Detect : –10°C ±3°C, Release : 0°C ±3°C

Note4 : Detection and release temperature change according to the spec (R, B constant) of NTC.
