Shanghai Mingda Microelectronics · Supervisor And Reset ICs · SOT-23-3L
MD7027C 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, CMOS push-pull on the MD7027C (normally high, active low) that goes low when VDD falls below the 2.7V detect threshold; output current is rated up to 10mA. |
| 2 | GND | power_in | Ground reference (VSS) for the voltage detector. |
| 3 | VDD | power_in | Supply and sensed voltage input; operating voltage 1.5V to 15V for the MD7027 with an absolute maximum of 18V. |
