8681l Ic Datasheet ((hot)) May 2026

, often found under the full part numbers , is a highly integrated SMBus Level 2 Battery Charge Controller

Steps

  1. Copy the full manufacturer part number from the datasheet's "Ordering Information" section. Example: 8681L-3.3V-5TR.
  2. Check life cycle status – If the datasheet says "Obsolete" or "Not for New Designs," consider an alternative.
  3. Purchase from authorized distributors – Mouser, Digi-Key, Arrow, or Newark.
  4. For large volumes – Contact manufacturer representatives directly (e.g., via their website).

Function and Feature Overview A typical 8681L-class IC often serves one of several common roles: a voltage regulator (linear or switching), a power MOSFET driver, a mixed-signal interface (ADC/DAC front-end), or a communication transceiver. Datasheets for these devices usually present a concise list of features up front: input voltage range, output characteristics (voltage, current, ripple, accuracy), switching frequency (if applicable), quiescent current, thermal limits, protection features (overcurrent, overtemperature, undervoltage lockout), package types, and key electrical characteristics such as dropout voltage, efficiency, or propagation delay. , often found under the full part numbers

Integration Challenges and Solutions Common integration issues include thermal overstress, electromagnetic interference (EMI) from switching regulators, unexpected stability problems due to improper output-capacitor ESR, and startup sequencing conflicts when multiple rails are involved. Mitigations include: Copy the full manufacturer part number from the

Dynamic Current Allocation: When the system is ON, the IC automatically allocates all remaining AC adapter current (not used by the system) to the battery charger to minimize charging time.
