Texas Instruments · Battery Management · HVSSOP-10-EP-0.5mm
BQ24091DGQR 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 from an external DC supply (AC adapter or USB port), with an expected bypass capacitor range of 1 µF to 10 µF connected from IN to VSS. |
| 2 | ISET | input | Programs the fast-charge current; an external resistor from ISET to VSS sets the value, with a range of 10.8 kΩ (50 mA) to 540 Ω (1000 mA). |
| 3 | VSS | power_in | Ground terminal; VSS must be connected to ground at all times, and the thermal pad must be tied to the same potential. |
| 4 | PRE-TERM | input | Programs the current termination threshold (5% to 50% of IOUT set by ISET) and sets the precharge current to twice the termination level, using a programming resistor of 1 kΩ to 10 kΩ. |
| 5 | PG | output | Power-good output: low (FET on) indicates the input voltage is above UVLO and the OUT (battery) voltage. |
| 6 | NC | unconnected | Do not make a connection to this pin, as it is for internal use and must not be routed through. |
| 7 | ISET2 | input | Selects the USB or adapter input/output current limit: high = 500 mA max, low = ISET, FLOAT = 100 mA max. |
| 8 | CHG | output | Charge status open-drain output: low (FET on) indicates charging, and open drain (FET off) indicates no charging or charge complete. |
| 9 | TS | input | Battery NTC temperature-sense input (100 kΩ at 25°C for BQ24091); floating or pulling high enters TTDM charger mode and disables TS monitoring, timers and termination, while pulling low disables the IC. |
| 10 | OUT | power_out | Battery connection for charge output; average system load should not be excessive so the battery can charge within the 10 hour safety timer window, with bypass capacitance of 1 µF to 10 µF. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
