SGM41600
I2C Controlled 6A Single-Cell Switched-Capacitor Fast Charger with Bypass Mode and ADC
The SGM41600 is an efficient 6A 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 11.5V 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.
A two-phase switched-capacitor topology is used to reduce the required input capacitors, improve efficiency and minimize the output ripple. Necessary protection features for safe charging performance including input over-voltage protection by external OVPFET (QOVP) and input reverse blocking (using an internal NFET) are provided.
A fast analog-to-digital converter (ADC) with 12-bit effective resolution is also included to measure die temperature, bus voltage, bus current, battery voltage and battery current (5 channels) for battery management of the charge process.
The SGM41600 is available in a Green WLCSP-2.6×2.6-36B package and can operate in the -40℃ to +85℃ ambient temperature range.
