SN6505BDBVR from Texas Instruments, in a SOT-23-6. 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 | D1 | output | Open-drain output of the first internal power MOSFET (~0.25 Ω R_ON at V_CC = 4.5 V, 1 A capable). Typically connected to one outer terminal of the center-tapped transformer primary; keep external traces short due to high current. |
| 2 | VCC | power_in | Device supply pin, 2.25 V to 5.5 V. Bypass with a 4.7 µF or greater low-ESR capacitor. Internal UVLO trips when V_CC ≤ 2.25 V (positive-going) / 1.7 V (negative-going) and turns off both outputs. |
| 3 | D2 | output | Open-drain output of the second internal power MOSFET (~0.25 Ω R_ON at V_CC = 4.5 V, 1 A capable). Typically connected to the other outer terminal of the center-tapped transformer primary; keep external traces short due to high current. |
| 4 | GND | power_in | Device ground; connects to the source of the internal power MOSFETs via an internal current-sense circuit. Must be connected to a low-inductance ground plane because large switching currents flow through it. |
| 5 | EN | input | Enable input. Logic high (V_IH ≥ 0.7 × V_CC) turns the device on; grounding or leaving floating disables all internal circuitry (I_DIS ≈ 0.1 µA). Tie directly to V_CC if unused. |
| 6 | CLK | input | External clock input to synchronize multiple devices. Internally pulled to GND; if no valid external clock is detected within t_CLKTIMER (10-25 µs), the device automatically falls back to its internal oscillator (420 kHz for SN6505B). |
