8682l Datasheet Jun 2026

Do not attempt to solder this IC with a standard soldering iron.

For those who require a deeper dive into the technical aspects of the 8682L, the datasheet provides a comprehensive overview of its technical specifications. These include:

: Portable computing motherboards and smart battery systems Thermal and Package Characteristics

The MC68HC812A4 is a 16-bit microcontroller unit (MCU) from the Motorola 68HC12 family. It is famous for its "Expanded Wide Bus" mode, allowing it to address large memory spaces, making it a favorite for automotive applications and university embedded systems courses.

Commonly used in the 820-2936-B logic board for managing power and charging cycles. Datasheet Resources 8682l Datasheet

The chip leverages a compact, leadless measuring small millimeter dimensions. The bottom of the IC features an exposed thermal pad that must be soldered directly to the PCB ground plane. This design facilitates rapid heat dissipation during high-frequency switching or high-current buck conversion. Thermal Thresholds

"Thermal data suggests an external constraint, not internal component failure," Aegis noted.

: SMBus Level 2 compliant . This allows the host microcontroller or Super I/O chip to read and dynamically program charge current and voltage thresholds.

Reduces BOM (Bill of Materials) cost by integrating current sensors and gate drivers for NMOS MOSFETs. Package Type: Available in a compact QFN-16 package. 3. Pin Configuration and Functions Do not attempt to solder this IC with

"Aegis, activate secondary cooling on node 8682L-Delta and bypass the 8682L’s passive sink," she ordered, grabbing her tablet to check the datasheet specifications. "Is it the driver or the chip?"

: Outputs pulse-width modulated (PWM) signals to control external synchronous buck MOSFETs. This translates high adapter voltages (typically 19V–20V) down into proper battery charging voltages (e.g., 8.4V, 12.6V, or 16.8V).

Suitable for Li-ion, Li-polymer, and other rechargeable battery chemistries.

The datasheet hinges on the "Mode of Operation," determined by the state of the MODA and MODB pins during reset. It is famous for its "Expanded Wide Bus"
