3 Description
The BQ25773 is a synchronous NVDC buck-boost
battery charge controller to charge a 2- to 5-cell
battery from a wide range of input sources including
USB adapter, extended power range (EPR) USBC
Power Delivery (PD) sources, standard power
range (SPR) USB-C Power Delivery (PD) sources
and traditional adapters. The device offers a low
component count, high efficiency solution for space
constrained, 2- to 5-cell battery charging applications.
The NVDC configuration allows the system to be
regulated based on battery voltage, but not drop
below system minimum voltage. The system keeps
operating even when the battery is completely
discharged or removed. When load power exceeds
input source rating, the battery goes into supplement
mode and prevents the system from crashing.
