MD7024 from Shanghai Mingda Microelectronics, in a SOT-23-3L. 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 | VOUT | output | Detector output, N-channel open drain (active low) for MD7024, which pulls low when VDD falls below the 2.4V detect voltage; sink current is 1.5 mV min at VOUT=0.2V with VDD=2.2V, absolute maximum output current 10mA. |
| 2 | GND | power_in | Ground (VSS) reference pin of the voltage detector. |
| 3 | VDD | power_in | Positive supply and voltage sense input, operating range 1.5V to 15V for MD7024 with absolute maximum of -0.3V to 18V. |
