The is a versatile component—likely a low-dropout regulator or a lithium battery protection IC. While an official, unified "8682l ic datasheet" is not hosted by major semiconductor brands (like TI, Analog, or Infineon), the technical specifications provided in this article offer a reliable engineering baseline.
(also known as the ) is an Integrated Circuit (IC) manufactured by . It primarily functions as a
This circuit is common in battery-powered IoT devices.
DC/DC converter and SMPS (Switched-Mode Power Supply) driver , commonly used as a battery charger controller in laptops and portable electronics. WIT Computers Key Technical Specifications Manufacturer: O2Micro International Package Type:
This prevents the battery from over-discharging (ruins Li-ion) or overcharging (fire risk).
If you find a datasheet for DW01 , XB8682 , or HM5802 , the pinout and electrical specs are often 95% compatible with the 8682L. Use those as a functional replacement after verifying pin 1 orientation.
The 8682L IC is likely used in a variety of applications, including:
Output of the transconductance error amplifier used for voltage loop compensation.
Exceeding 10V on the supply pin will likely destroy the 8682L.
| Pin Number | Pin Name | Description | | :--- | :--- | :--- | | 1 | VIN | Input voltage (2.5V to 6V) | | 2 | GND | Ground | | 3 | EN | Enable pin (Active High) | | 4 | NC | No connect | | 5 | VOUT | Regulated output (typically 1.8V, 2.8V, or 3.3V) |
This technology enables the system to draw power from both the AC adapter and the battery simultaneously to meet high-current demands during intensive tasks.
