BQ24090DGQT

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

BQ24090DGQT 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 input Input power from the external DC supply (AC adapter or USB port), with an expected bypass capacitor 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.
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 current level, with an expected programming resistor range 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 the OUT (battery) voltage.
6 NC unconnected Do not make a connection to this pin; it is for internal use and the signal must not be routed through it.
7 ISET2 input Programs the input/output current limit for the USB or adapter source: high = 500 mA max, low = ISET, float = 100 mA max.
8 CHG output Open-drain charge status output: low (FET on) indicates charging, and open drain (FET off) indicates no charging or charge complete.
9 TS input Battery-pack NTC temperature sense input (10 kΩ at 25°C for the BQ24090); floating or pulling high puts the part in TTDM charger mode and disables TS monitoring, timers and termination, and pulling it low disables the IC.
10 OUT output Battery connection to which the system load may be connected; the average load should not be excessive so the battery charges within the 10-hour safety timer window, with an expected bypass capacitor of 1 µF to 10 µF.
11 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).
