SGM41606S
I2C Controlled, Single-Cell 8A Switched Cap Parallel Battery Charger with Bypass Mode and Dual-Input Selector
The SGM41606S 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 3.6V 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 SGM41606S 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 17mΩ (TYP) 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 SGM41606S is designed to support a dual input setup using an integrated multiplexer control and driver for external OVPFETs. Additionally, it also supports single input without OVPFET or with just a single OVPFET.
The SGM41606S is available in a Green WLCSP-2.65×2.65- 36B-A package and can operate in the -40℃ to +85℃ ambient temperature range.
