SPECIFICATION
Product Name: Li-Po battery protection module
Item Number:
15 51 51
Features:
The module will protect a single rechargeable lithium polymer battery.
Its high accuracy is predestinated for protection against overcharge, overdischarge and overcurrent.
This module interrupted the connection between Li-Po battery and charging device or any load,
if an error occurs. When the error was eliminated, the connection is automatically restored.
Electrical Parameter:
•
• Overcharge detection voltage
• Overdischarge detection voltage
• Delay times are generated by an internal circuit
• Three-step overcurrent detection circuit is included
(Overcurrent 1, overcurrent 2 and load short-circuiting)
• Charger detection function and abnormal charge current detection function
• Wide operating temperature range -40 to +85 °C
Internal high accuracy voltage detection circuit
Note:
This Li-Po battery protection module is a “non-CE-checked” component. The utilisation must comply with the CE norms.
