8682l Ic Datasheet Updated Jun 2026

Look for a small logo on the IC:

The 8682L can be integrated on a carrier board for the Pico, charging a backup Li-ion cell while the Pico runs from USB or battery.

For engineers seeking alternative parts, several component cross‑reference tools can help identify pin‑compatible replacements:

The 8682L does not support currents above 800mA reliably in SOT-23-6 package due to thermal limitations. For higher currents, choose a different IC.

The OZ8682’s ACIN_PG signal turned on PQ7, which caused PQ10 to turn off, allowing the +3VPCU pull‑up to drive the EC’s ACIN pin high. A leaky PQ10 pulled the signal low, preventing adapter detection. Replacing PQ10 resolved the issue.

The physical footprint of the 8682L utilizes a (

The GATE pin sends a high-frequency signal to an external N-channel MOSFET.

Based on common technical documentation for the OZ8682L series, the device features:

Gate driver outputs that control the external input N-channel MOSFETs. These isolate the DC adapter if an overcurrent or reverse-polarity fault is detected.

Lead times vary by supplier. Some distributors maintain stock and offer same‑day shipping, while others may have lead times of several weeks. Always check with your preferred distributor for current availability.

: Because it uses a QFN-16 format, the central exposed thermal pad must be soldered flawlessly to the PCB ground plane. Poor contact will trigger internal over-temperature protections, forcing the IC to prematurely shut down power lines.

Test the internal reference voltage pin (typically generating 3.3V or 5V). An absent or fluctuating LDO voltage points to a dead IC or a localized ceramic capacitor short circuit.

Given that the 8682L is not always listed on mainstream sites like Texas Instruments or Mouser, you must use alternative sources:
