SN6505DQDBVTQ1

Texas Instruments · Power Management - Specialized · SOT-23-6

SN6505DQDBVTQ1 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 output Open-drain output of the first power MOSFETs, typically connected to the outer terminals of the center-tap transformer, and its external trace should be kept short because large currents flow through it.
2 VCC power_in Device supply pin that should be bypassed with a 4.7 µF or greater, low-ESR capacitor, and an internal undervoltage lockout turns both outputs off when VCC ≤ 2.25 V.
3 D2 output Open-drain output of the second power MOSFETs, typically connected to the outer terminals of the center-tap transformer, and its external trace should be kept short because large currents flow through it.
4 GND power_in Ground connected to the power MOSFET switch sources through an internal sense circuit, which must be tied to a low-inductance quality ground plane because large currents flow through it.
5 EN input Enable pin that turns the device on or off, where grounding or leaving it floating disables all internal circuitry, and if unused it should be tied directly to VCC.
6 CLK input External clock input, internally pulled down to GND, where the device automatically shifts to the internal clock if a valid clock is not detected on this pin.
