SGM41608
I2C Controlled, Single-Cell 8A Switched Cap Parallel Battery Charger with Bypass Mode
The SGM41608 is an efficient 8A switched-capacitor battery charging device with I2C control that can operate either in charge-pump voltage divider mode or in bypass mode. It can charge single-cell Li-Ion or Li-polymer battery in a wide 3.3V to 12V input voltage range (VBUS) from smart wall adapters or power banks. The switched-capacitor architecture is optimized for 50% duty cycle to cut the input current to one-half of the battery current and reduce the wiring drops, losses and temperature rise in the application.
The SGM41608 is equipped with the capability to facilitate a 5A bypass mode charge, formerly known as battery switch charge, via its built-in MOSFETs. The RDSON value for the charging path in bypass mode is kept under 15mΩ to accommodate high current operations. This integrated bypass mode ensures that a 5V fast charging adapter can be used to charge a single-cell battery, thereby maintaining backward compatibility.
The SGM41608 is available in a Green WLCSP-2.38×2.38-35B package.
