8681l Ic — Datasheet __full__
A critical table showing the safe operating limits for supply voltage, input voltage, output voltage, ground pin current, and power dissipation.
It is almost certainly a misprint, factory code, or obsolete non-standard part. If you found it in a circuit, trace the pins and measure function to identify a replacement.
If the 8681L has an EN pin and you leave it floating, the internal state is undefined. The device may remain off or oscillate. Always tie EN to VIN or a logic high.
It is often confused with its sibling, the 8681 (without the 'L'), which operates at higher current. The typically denotes a low-power or low-current version , making it ideal for battery-operated handheld GNSS receivers. 8681l ic datasheet
Internal reference voltage output for decoupling and accuracy stabilization. IIN / ACP Positive input for the AC adapter current-sense resistor. 9 ACN Negative input for the AC adapter current-sense resistor. 10 CHG / SRP
While some retail listings broadly classify it for generic electronic uses, the genuine laptop IC uses a 16-pin QFN pattern. Important connections on the chip include:
: A similar, more advanced model featuring dedicated hardware accelerators for real-time tasks. Procurement and Availability New and original OZ8681L/LN chips are available through several retailers: A critical table showing the safe operating limits
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.
: Includes anti-interference designs and high-precision data measurement for GPS and medical sensors. Sourcing and Compatibility
This IC is a critical component for power management on laptop motherboards. You will most frequently find it in: If the 8681L has an EN pin and
Note: Some 3-pin SOT-89 versions omit the EN pin and NC.
