Customer ServiceThe battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
At this low current, the time the Li-Ion battery takes to reach the end-of-discharge voltage is significantly extended. For other protection circuitry that typically requires higher current, the rate of discharge is faster, allowing the battery voltage to drop below the safe limit in a shorter time.
High & low temperature: is when the internal temperature of the battery cells exceeds their safe operational temperature ranges. Over-discharge: is when the battery is discharged under the allowed minimum capacity. Over-current: is when the battery is exposed to a short circuit condition or a high inrush turn-on current.
The LT1495 is available in plastic 8-pin PDIP and SO-8 packages with the standard dual op amp pinout. Consuming virtually no current, the LT1389 and the LT1495 are ideal choices for the UVLO circuit and many other battery applications.
A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. Over-charge: is when the battery is charged over the allowed maximum capacity.
