Product details

Single-cell linear charger for Li-Ion/Polymer packs

The Texas Instruments BQ24070RHLT is a single-cell linear charger IC designed for Lithium Ion/Polymer battery packs. It delivers a programmable constant charge current up to 1.5 A max, with a fixed 4.2 V battery regulation voltage. 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.

1.5 A charge current and programmable features

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.

Frequently asked questions

What is the charge current of BQ24070RHLT?

The BQ24070RHLT supports a programmable constant charge current with a maximum of 1.5 A. The actual current is set by an external resistor.
