BQ294522DRVT from Texas Instruments, in a WSON-6-EP(2x2). 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 | V3 | input | Analog sense input for the positive voltage of the third cell from the bottom of the stack; input leakage current ±0.1 µA max (0 °C to 60 °C), abs max V3-VSS = 30 V; for 2-series configuration, short to V2. |
| 2 | V2 | input | Analog sense input for the positive voltage of the second cell from the bottom of the stack; input leakage current ±0.1 µA max (0 °C to 60 °C), abs max V2-VSS = 30 V. |
| 3 | VSS | power_in | IC ground; electrically connected to the negative terminal of the lowest cell in the stack; must be connected to PWRPAD on PCB for proper operation. |
| 4 | V1 | input | Analog sense input for the positive voltage of the lowest cell in the stack; input leakage current ±0.1 µA max (0 °C to 60 °C), abs max V1-VSS = 30 V. |
| 5 | VDD | power_in | Unregulated power supply input for the IC; recommended operating range 3 V to 25 V, abs max VDD-VSS = 30 V; connect series resistor RVD (100 Ω-1 kΩ) and bypass capacitor CVD (0.1 µF) for noise filtering. |
| 6 | OUT | output | Active-high analog output drive for gate of external N-channel FET; VOUT ≥ 6 V at IOH = 100 µA with VDD = 7.2 V in overvoltage condition; output impedance 2-5 kΩ; abs max OUT-VSS = 30 V. |
| 7 | PWRPAD | power_in | Exposed thermal pad; must be soldered and connected to VSS on the PCB for proper electrical and thermal operation; RθJA = 186.4 °C/W. |
