8681l Ic Datasheet Pdf Hot Download [verified] Page
The 8681L IC operates as a Pulse Width Modulation (PWM) synchronous buck battery charger. It handles system power distribution dynamically by allocating excess current from the AC adapter straight to the battery cell. Specification Details OZ8681L / OZ8681LN / OZ8681 Manufacturer O2Micro International Ltd. Package Type QFN-16 (Quad Flat No-Leads, 16 Pins) Communication Protocol System Management Bus (SMBus) Programmable Battery Chemistry Multi-chemistry (Li-Ion, Li-Polymer, etc.) Mounting Style Surface Mount Device (SMD / SMT) Operating Temperature -40°C to +85°C Core Architecture and Functional Principles 1. SMBus Programmability
The inclusion of the SMBus interface allows the host microcontroller or embedded controller (EC) to alter charging parameters seamlessly. Technicians can configure: Charging voltage limits. Charging current limits. Overcurrent protection thresholds. 2. Dynamic Power Allocation
Check the capacitor between BOOT and PHASE. A leaked or open bootstrap capacitor stops the high-side MOSFET from turning on entirely. 8681l ic datasheet pdf hot download
If the internal junction temperature exceeds approximately 150°C, the IC automatically disables the power stage until the die cools down to safe operational limits. Under-Voltage Lockout (UVLO)
High-voltage internal power MOSFET drain connection. Multiple pins are paired to optimize thermal dissipation on the PCB copper plane. Advanced Built-In Features The 8681L IC operates as a Pulse Width
