Frequently Asked Questions
Which USB Power Delivery voltages can the MAX77860EWG+ accept as a charger input?
The MAX77860EWG+ accepts USB Type-C VBUS input voltages of 5V, 9V, and 12V compatible with USB PD profiles, allowing up to 3A charge current and approximately 15W maximum charging power into a single-cell Li-ion battery in a compact WLCSP package.
How does the reverse boost mode of the MAX77860EWG+ work in a power bank design?
In reverse boost mode the MAX77860EWG+ boosts the 3.0–4.2V Li-ion battery voltage up to a regulated 5V output on the VBUS rail, enabling the host device to supply up to 1A to connected USB accessories via the USB Type-C port, converting any device equipped with this IC into a USB OTG power source.
What does the integrated 10-bit ADC in the MAX77860EWG+ measure and why is it useful for firmware?
The integrated 10-bit ADC continuously samples VBUS input voltage, battery voltage VBAT, system voltage VSYS, and charge current IBAT, providing firmware with up to 1024-level resolution on each channel. This allows accurate state-of-charge estimation and input power monitoring without external analog measurement circuits, reducing BOM count in space-constrained 81-ball WLCSP smartphone designs.
