The 1 A max charge current is the thermal design ceiling for the 10-WSON (3x2) package. The battery pack voltage is 3.5 V.
On-chip fault protection covers over-temperature and over-voltage, reducing the need for external supervisory components. The USB interface allows direct connection to a standard USB port or a dedicated USB power source without level-shifting.
The maximum charge current is 1 A, programmable via an external resistor. The battery pack voltage is 3.5 V, designed for single-cell LiFePO4 packs with a 3.2 V nominal cell voltage.
Yes, the BQ25070DQCR is supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly.
