Texas Instruments · Power Management - Specialized · SOT-23-6
SN6505BQDBVTQ1 from Texas Instruments, in a SOT-23-6. 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 | D1 | tri_state | Open drain output of the first power MOSFET stage for connection to center-tap transformer secondary; external traces must be kept short due to large current flow. |
| 2 | VCC | power_in | Device supply pin that must be bypassed with 4.7 μF or greater low ESR capacitor; internal UVLO circuit disables outputs when VCC ≤ 2.25 V. |
| 3 | D2 | tri_state | Open drain output of the second power MOSFET stage for connection to center-tap transformer secondary; external traces must be kept short due to large current flow. |
| 4 | GND | power_in | Ground connected to power MOSFET switch sources via internal sense circuit; must be connected to low-inductance quality ground plane due to large current flow. |
| 5 | EN | input | Active-high enable input that turns the device on or off; floating or grounded disables all internal circuitry; tie to VCC if unused. |
| 6 | CLK | input | External clock input with internal pull-down to GND; device automatically switches to internal clock if valid external clock is not detected. |
