Product details

What this charger IC does and who specifies it

The BQ24080DRCT is a linear charger IC from Texas Instruments designed for single-cell Lithium Ion/Polymer battery packs.

Charge current, timer, and thermal envelope

The 1A max charge current is the headline figure, but the real-world charge rate is set by the external resistor on the ISET pin — you pick the current that matches the cell capacity and the thermal budget of the 10-VSON pad. The timer pin adds a safety timeout (hours = R_TMR × C_TMR / constant) that stops charging if the battery never reaches the 4.2V termination.

Frequently asked questions

What is the charge current of BQ24080DRCT?

The maximum charge current is 1A, programmable via an external resistor on the ISET pin. The actual charge rate is set by the resistor value and must stay within the thermal limits of the 10-VSON package.

What is the closest pin-compatible alternative to BQ24080DRCT?

The BQ24080 family includes the BQ24080DRCR (same die, same 10-VSON package, different tape/reel suffix). The BQ24070 and BQ24090 series offer similar single-cell linear charging but differ in pinout and feature set — verify compatibility against the datasheet before substituting.
