P = (VIN - VOUT) * IOUT = (5.0 - 3.3) * 0.3 = 0.51 Watts

The system shuts down immediately upon removing the charger. Repair Steps (Based on Component Functionality)

Connects to external high-side current resistors to monitor adapter and charging current loops.

For the OZ8681LN, pricing information is available, which can be a critical part of a bill of materials or a repair assessment. Pricing is often tiered based on quantity:

A typical application circuit for the 8681L consists of:

: The chip operates strictly within the Smart Battery System (SBS) guidelines. It acts as a slave device that receives voltage and current regulation parameters directly from the intelligent circuitry inside the battery pack itself. Key Specifications & Absolute Maximum Ratings

When a direct datasheet is unavailable, that provide parametric search across multiple manufacturers can be used. Entering key electrical specifications can generate a list of functionally equivalent components.

The top marking is a code. The first line might be "8681L" (lot code) while the output voltage is indicated by a subsequent digit or letter. Read the datasheet's "Marking Information" section carefully.
