# BQ24092DGQT

**Texas Instruments** · Battery Management · HVSSOP-10-EP-0.5mm

BQ24092DGQT from Texas Instruments, in a HVSSOP-10-EP-0.5mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input power connected to external DC supply (AC adapter or USB port) with 1 μF to 10 μF bypass capacitors to VSS. |
| 2 | ISET | input | Fast-charge current programming resistor to VSS determines charge current with range from 50 mA (10.8 kΩ) to 1000 mA (540 Ω). |
| 3 | VSS | power_in | Ground terminal. |
| 4 | PRETERM | input | Programs current termination threshold (5 to 50% of Iout) and sets pre-charge current to twice termination level with 1 kΩ to 10 kΩ programming resistor. |
| 5 | PG | output | Power good output; indicates low when input voltage is above UVLO and OUT (battery) voltage. |
| 6 | NC | unconnected | Do not connect to this pin; reserved for internal use. |
| 7 | ISET2 | input | Programs input/output current limit for USB or adaptor source; high = 500 mA max, low = ISET, float = 100 mA max. |
| 8 | CHG | output | Charging status output; low (FET on) indicates charging and open drain (FET off) indicates no charging or charge complete. |
| 9 | TS | input | Temperature sense pin for 10 kΩ NTC thermistor in battery pack; floating or high disables monitoring via TTDM mode. |
| 10 | OUT | power_out | Battery connection with 1 μF to 10 μF bypass capacitors; system load may be connected if average load allows battery to charge within 10-hour safety timer window. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
