8682l Ic Datasheet 'link' Instant

(full part number ) is a specialized power management integrated circuit (PMIC) manufactured by . It is primarily used as an SMBus Level 2 Battery Charger

: You can find replacement chips from electronic component retailers like Nexsys Techno or Motherboard.lk . Common Identification Marking Marking on Chip : Usually labeled as 8682L or OZ8682LN .

Based on technical archives and component listings, here are the core parameters for the OZ8682LN: OZ8682LN / OZ8682L Package Type: QFN-16 (Quad Flat No-lead, 16 pins) 8682l ic datasheet

According to the O2Micro Product Guide , the OZ8682L features:

The is frequently mentioned as a possible alternative to the OZ8682L. However, compatibility is not guaranteed. Repair technicians have noted that the OZ8681L may have different internal configurations, and direct substitution can lead to unexpected behaviour. (full part number ) is a specialized power

In a standard LED driver circuit, the 8682L acts as the "brain." The IC receives voltage at the VIN pin.

| Condition | CHRG (Red) | STDBY (Green) | Battery current | |-------------------------------|-------------------|-------------------|-----------------| | No battery (or BAT > 4.25V) | Off (high-Z) | Off (high-Z) | 0mA | | VCC missing (USB unplugged) | Off | Off | 0mA (load from battery? none) | | Trickle charge (BAT < 2.9V) | On (low) | Off (high-Z) | ~10% I_prog | | Constant current / constant voltage charging | On (low) | Off (high-Z) | I_prog down to 1/10th | | Charge complete (BAT=4.20V) | Off (high-Z) | On (low) | 0mA (or very low) | | Over-temperature (die >120°C) | Blinking (0.5Hz)?* | Off/Blinking* | Reduced current | Based on technical archives and component listings, here

Finding a full public PDF datasheet for the 8682L can be challenging because it is often a discontinued or proprietary part. For hardware repair, it is frequently compared with the EA3059QDR for parametric compatibility. (5piece)100% New 8682L OZ8682L OZ8682LN QFN-16 Chipset

Stability note: Unlike some modern LDOs, the 8682L requires output capacitors with controlled ESR. Ultra-low ESR ceramic caps alone may cause oscillations; adding a 0.5Ω resistor in series is a common fix.

The (primarily manufactured as the OZ8682LN by O2Micro ) is a highly specialized, surface-mount SMBus Level 2 Battery Charger and Power Management Integrated Circuit (PMIC) . Widely integrated into modern laptop motherboards, portable electronics, and complex battery-powered equipment, this IC features a Hybrid Power Boost system. This allows the device to draw simultaneous power from both the AC adapter and the battery pack to cover peak system loads.

The 8682L resolves this bottleneck by allowing the battery pack to operate concurrently with the AC adapter. When the overall load approaches a designated maximum threshold, the chip stops charging the battery and switches modes, drawing supplementary current from the battery pack to boost the primary rail.
