Manual MXT141
Internal Battery
•
Rated Voltage: 3.7V
•
Capacity: 850 mAh;
•
Battery fault detection;
•
Operating Temperature Range/Humidity: for Charge 0 ~ +45 45 ‐ 85% RH, for Discharge ‐
20 ~ +60 45 ‐ 85% RH;
•
Over Charge Prohibition: Shut down the circuitry and stop charge if the battery’s voltage
exceeds more than 4.325±0.025V momentarily or continuously.
•
Over Charge Release: If the battery voltage is less than: 4.075±0.025V prohibition mode
would be "Reset" and "Start reload".
•
Over Discharge Prohibition: Shut down circuitry and stop discharge if the voltage becomes
less than 2.5±0.05V momentary or continuously.
•
Over Discharge Release: Recover when the voltage reaches above: 2.9±0.05 V.
•
Short circuit protection: When protection IC detects the voltage drop on MOS exceeds the
specified voltage ( 0.8 V(min.), 1.1 V(typ.), 1.4 V(max.) ), it shall shut the circuit and stop
discharge;
•
Charging Thermal Regulation Prevents Overheating: Charging is suspended when the
battery pack temperature is over +50 .
