The 8682L typically controls external MOSFETs (Q1, Q2). If the IC is working, the MOSFETs should be switching.
Primarily used in laptop battery charging circuits and system power management.
: Provides high-efficiency buck-boost control configurations for high-capacity multi-cell lithium batteries. Troubleshooting and Repair Guidelines 8682l ic datasheet
The is typically a single-cell lithium-ion battery charger IC and power path management device. It is commonly found in:
: Typically available in a QFN16 (16-pin Quad Flat No-lead) or 28-pin package depending on the specific sub-variant and board implementation. The 8682L typically controls external MOSFETs (Q1, Q2)
The OZ8682L comes in a with hidden contacts underneath the chip. This requires specialized handling and is not suitable for basic soldering tools.
