The 16 V max supply input accepts common USB or 5 V wall-adapter rails, with built-in over-temperature, reverse-current, and short-circuit fault protection.
Charge current is constant and programmable via an external resistor, with a 1.5 A maximum ceiling. The IC also includes a programmable timer for charge termination, giving the designer control over charge profile without a host MCU.
The BQ24070RHLT supports a programmable constant charge current with a maximum of 1.5 A. The actual current is set by an external resistor.
