Product details

1.5 A programmable charge current with USB input

The BQ24072RGTR is a single-cell Li-Ion linear charger that delivers up to 1.5 A of programmable charge current from a USB or 6.4 V max supply rail. The constant-current value is set with a single resistor; the timer sets the termination window.

Single-cell fit and protection suite

This part charges exactly one series Li-Ion cell to 4.2 V. It will not charge a 2S pack — that requires a different charger IC. The built-in fault protection covers over-temperature, over-voltage, reverse-current, and short-circuit conditions, which means you can omit external comparators and current-limit fets in most portable designs.

Active production, qualified to 125°C junction

The 16-VFQFN package is supplied on tape-and-reel (cut tape available). Sourcing is confirmed per RFQ; no stock or lead-time claim is made here.

Frequently asked questions

Can the BQ24072RGTR charge a 2-cell (2S) battery pack?

No. The BQ24072RGTR is designed for a single Li-Ion cell with a 4.2 V pack voltage. It lacks the voltage rating and cell-balancing logic for 2S charging. For a 2-cell application, look at the BQ24073, which adds a charge-enable pin and timer-disable feature for multi-cell topologies.

Is the BQ24072RGTR pin-compatible with the BQ24073?

The BQ24072 and BQ24073 share the same base number and 16-VQFN footprint, but the BQ24073 adds a charge-enable (CE) pin and a timer-disable (TMR_DIS) pin. Verify the pinout on the respective datasheets before substituting — the extra pins may conflict with your existing layout if the PCB uses those positions for other signals.
