BQ294512DRVT from Texas Instruments, in a WSON-6-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | V3 | input | Sense input for the positive terminal of the third (top) cell in the stack. Analog cell-voltage sense; input current <100 nA typical. Absolute max V3-VSS = 30 V; V3-V2 = 8 V max. Recommended operating range V3-V2 = 0 V to 5 V. |
| 2 | V2 | input | Sense input for the positive terminal of the second (middle) cell in the stack. Analog cell-voltage sense; input current <100 nA typical. Absolute max V2-VSS = 30 V; V2-V1 = 8 V max. |
| 3 | VSS | power_in | IC ground; electrically connected to the negative terminal of the lowest cell (Pack-). Must be tied to the exposed thermal PWRPAD on the PCB for proper operation. |
| 4 | V1 | input | Sense input for the positive terminal of the lowest (bottom) cell in the stack. Analog cell-voltage sense; input current <100 nA typical. Absolute max V1-VSS = 30 V; recommended V1-VSS = 0 V to 5 V. |
| 5 | VDD | power_in | Device supply voltage referenced to VSS. Recommended operating range 3 V to 25 V; absolute max VDD-VSS = 30 V. Typical ICC ≈ 1 µA when all cells are below VPROTECT. |
| 6 | OUT | output | Analog output drive for an external N-channel FET (secondary-protection blow-fuse/disconnect). Drives high when any monitored cell exceeds VOV for the fixed tDELAY (4 s for BQ294512). VOH ≥ 6 V at IOH = 100 µA with VDD = 7.2 V; short-circuit current ≈ 4.5 mA; output impedance 2-5 kΩ; rise time ≈5 µs with CL = 1 nF. Absolute max OUT-VSS = 30 V. |
| PAD | PWRPAD | passive | Exposed thermal pad on the bottom of the SON-6 (DRV) package. Must be connected to VSS (pin 3) on the PCB for proper device operation and thermal performance. |
