Shanghai Mingda Microelectronics · Supervisor And Reset ICs · SOT-89-3
MD7044 from Shanghai Mingda Microelectronics, in a SOT-89-3. 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 and active low for the MD7044, with 10mA maximum output current and 4mA minimum sink current at VOUT=0.2V. |
| 2 | VDD | power_in | Positive supply input and detection voltage sense, with 1.5V to 15V operating voltage and an absolute maximum of -0.3V to 18V. |
| 3 | GND | power_in | Ground (VSS) reference for the supply and output. |
