Description

The GLF3006 is a highly integrated solution for single cell rechargeable battery protection. It incorporates a low on-resistance power NFET along with high precision over voltage, over current, over discharge, and short circuit protection.


When the battery voltage exceeds the over-voltage detection threshold, the GLF3006 turns off the charging switch after a preset delay. Similarly, if the load current surpasses the over discharge current threshold, the discharge switch is turned off after a preset delay. If the discharge current reaches the short circuit protection level (ISC), the GLF3006 immediately shuts down and remains off to prevent serious system damage. A short circuit delay is included to avoid false triggering.
