Datasheet: 8681l Ic

Possibly, but check first. The 78L33 has a different pinout (1-Output, 2-GND, 3-Input in TO-92). The 8681L in SOT-23 likely has a different pin arrangement (e.g., 1-GND, 2-Input, 3-Output). Do not substitute without verifying.

: Due to its surface-mount design and critical role in power delivery, replacement should be performed by qualified personnel using specialized soldering tools.

: Often interchangeable or used alongside variants like the OZ8681LN, OZ8682L, and OZ8618LN. 8681l ic datasheet

The most common component confused with this marking is the .

: Connections that turn power-controlling transistors (MOSFETs) on and off. Common Signs of a Broken 8681L Chip Possibly, but check first

While exact pinouts can slightly vary based on the motherboard vendor’s proprietary schematics, a typical QFN-16 layout for the O2Micro 8681L family allocates functions as follows: Pin Number Description / Technical Function VDD / VCC Main power supply input pin for the IC logic. 2 ACIN

The laptop works on the battery but will not charge when plugged in. Do not substitute without verifying

RDS(ON)cap R sub cap D cap S open paren cap O cap N close paren end-sub high-side and low-side switches.

: Includes safeguards against incorrect voltage, short circuits, and internal overheating.

When working with ambiguous parts like the "8681L," a thorough approach is required beyond just finding a datasheet.

Once power and enable are verified, measure the voltage drop across the current sense resistors connected to the IACP, IACM, and ICHM pins. Unusual readings here can indicate a problem with the current sensing network or the power path.
