Controls external High-Side and Low-Side MOSFETs for synchronous rectification. Current Sensing Input
Note: Always cross-reference this example with your downloaded PDF, as exact pin assignments vary wildly between different chip designs. Part 4: 8681L IC Installation and Soldering Guide
: Shuts down the IC if internal temperatures exceed safe limits (usually around 150°C). 3. 8681L Pinout Configuration 8681l ic datasheet pdf download install
: Link the 8681L pinout to your schematic capture program.
Implementing the 8681L requires a few critical peripheral passive components to function correctly. Multi-chemistry (primarily Li-Ion and Li-Polymer).
Differential sensing inputs wired across external shunt resistors to monitor adapter and battery draw. HDRV / LDRV / PHASE
: Highly integrated, SMBus programmable, multi-chemistry battery charge controller. Package : Typically available in a QFN-16 package. internal high-side MOSFET
The loop consisting of the input capacitor, internal high-side MOSFET, and internal low-side MOSFET carries high-frequency switching currents. Place CINcap C sub cap I cap N end-sub immediately adjacent to the chip pins.
