Functional Description:
The STL1033-001 provides both safety and battery management functions for 1-cell Lithium
Ion battery packs. In addition to preventing overvoltage during charge mode, undervoltage
during discharge mode, and overcurrent during discharge mode, the STL1033-001 actively
regulates charge current and voltage to ensure optimal battery charging.
