Frequently Asked Questions

What is the maximum charge current supported by PQ25792RQMT and how is it configured?

The PQ25792RQMT supports up to 5 A charge current, programmed via I2C commands. This allows dynamic adjustment between system states, enabling aggressive 5 A fast-charge when thermal budget permits and reduced current for trickle or maintenance charging of 1–4 cell Li-Ion packs.

Which battery cell configurations work with PQ25792RQMT for a USB-C power bank design?

PQ25792RQMT supports 1 to 4 series Li-Ion cells, making it suitable for power banks ranging from single-cell 3.7 V packs up to 4S 16.8 V configurations. The buck-boost topology maintains regulated 5 A output even when the input voltage from a 20 V USB PD adapter is close to the battery voltage.

How does the dual-input selector in PQ25792RQMT simplify PCB design for laptops with both USB-C and wireless charging inputs?

The integrated dual-input selector automatically arbitrates between two power sources without external OR-ing FETs, reducing BOM count and board area. It supports input voltages from 3.9 V up to 25.7 V OVP threshold, covering USB PD adapters up to 20 V and wireless charging receivers, while protecting downstream circuits from overvoltage events.

What package does PQ25792RQMT use and what are the key thermal considerations?

PQ25792RQMT is housed in a 29-pin VQFN (S-PQCC-N29) plastic/epoxy package with a 0.17-inch square exposed thermal pad. Operating at up to 5 A, designers should ensure adequate copper pours and vias beneath the thermal pad to maintain junction temperature within the rated range for reliable continuous operation.
