# BQ24095DGQT

**Texas Instruments** · Battery Management · HVSSOP-10

BQ24095DGQT from Texas Instruments, in a HVSSOP-10. 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 from an AC adapter or USB port; absolute maximum is 12 V with respect to VSS, and a 1 µF to 10 µF bypass capacitor is expected from IN to VSS. |
| 2 | ISET | input | Fast-charge current program pin; an external resistor from ISET to VSS sets the charge current, with a range of 10.8 kΩ (50 mA) to 540 Ω (1000 mA). |
| 3 | VSS | power_in | Ground terminal; it must be connected to ground at all times. |
| 4 | PRE-TERM | input | Programs the current termination threshold (5% to 50% of the ISET-set charge current) and sets the precharge current to twice the termination level, using a programming resistor of 1 kΩ to 10 kΩ. |
| 5 | PG | output | Open-drain power-good output; low (FET on) indicates the input voltage is above UVLO and above the OUT (battery) voltage. |
| 6 | NC | unconnected | Not connected for internal use; do not make a connection to this pin and do not route signals through it. |
| 7 | ISET2 | input | Selects the USB or adapter input current limit: high sets 500 mA max, low sets the limit to ISET, and float sets 100 mA max. |
| 8 | CHG | output | Open-drain charge-status output; low (FET on) indicates charging and open drain indicates no charging or charge complete, with a sink current rating of 15 mA maximum. |
| 9 | TS | input | Battery NTC temperature-sense input (10 kΩ NTC at 25°C for the BQ24095); floating or pulling high enters TTDM mode and disables TS monitoring, timers and termination, while pulling low disables the IC. |
| 10 | OUT | power_out | Battery connection and charger output, with a 1 A recommended operating current and 1.25 A absolute maximum continuous output current, and a 1 µF to 10 µF bypass capacitor expected. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `BQ24095DGQT`
- Footprint: `Package_SO:HVSSOP-10-1EP_3x3mm_P0.5mm_EP1.83x1.89mm`
- 3D model: HVSSOP-10, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.0 mm nominal HVSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `bq24095dgqt-etched.step` / `bq24095dgqt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bq24095dgqt.step` / `bq24095dgqt.glb` are the bare package body.
