MX6505T from Wuxi Maxinmicro, 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 terminal of the center-tap transformer; keep its traces short because large currents flow through it (D1/D2 absolute max is -0.3 to 36V, with 2.4A peak current).
2	VCC	power_in	Device supply pin, recommended 2.25V to 5.5V, to be bypassed with a 4.7µF or greater low-ESR capacitor; when VCC ≤ 2.25V the internal undervoltage lockout turns both outputs off.
3	D2	output	Open-drain output of the second power MOSFETs, typically connected to the outer terminal of the center-tap transformer; keep its traces short because large currents flow through it (D1/D2 absolute max is -0.3 to 36V, with 2.4A peak current).
4	GND	power_in	Ground, connected to the source of the power MOSFET switches via an internal sense circuit; the GND pins must be tied to a low-inductance ground plane because of the large currents.
5	EN	input	Enable input that turns the device on or off; grounding it disables all internal circuitry (EN/CLK absolute max is -0.5 to VCC+0.5V, and the logic-high threshold is 0.4 to 0.7 VCC).
6	CLK	input	External clock input (100 kHz to 2000 kHz) that is internally pulled down to GND; if a valid clock is not detected the device automatically switches to the internal 420 kHz clock after tCLKTIMER (350 µs).
