Mysentech · Float Level Senors · QFN-20-EP(3x3)
MDC04 from Mysentech, in a QFN-20-EP(3x3). 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 | RSTN | input | Active-low reset input; pulling it low for at least 1 µs resets the sensor, and it is internally pulled up to VDD. |
| 2 | MODE | input | Interface mode select: when low (0) PIN12 is the I²C SDA line, when high (1) PIN12 is the 1-Wire DQ line; tie to VDD for 1-Wire and to GND for I²C. |
| 3 | VSS | power_in | Power ground for the device. |
| 4 | C4_OUT | output | Analog output terminal for external capacitor C4 (channel 4 sense electrode). |
| 5 | C4_IN | input | Analog input terminal for external capacitor C4 (channel 4 sense electrode). |
| 6 | C1_IN | input | Analog input terminal for external capacitor C1 (channel 1 sense electrode). |
| 7 | C1_OUT | output | Analog output terminal for external capacitor C1 (channel 1 sense electrode). |
| 8 | C2_IN | input | Analog input terminal for external capacitor C2 (channel 2 sense electrode). |
| 9 | C2_OUT | output | Analog output terminal for external capacitor C2 (channel 2 sense electrode). |
| 10 | C3_IN | input | Analog input terminal for external capacitor C3 (channel 3 sense electrode). |
| 11 | C3_OUT | output | Analog output terminal for external capacitor C3 (channel 3 sense electrode). |
| 12 | SDA/DQ | bidirectional | I/O carrying I²C data (when MODE=0) or the 1-Wire data line (when MODE=1); it needs an external pull-up to VDD (Rup 1-100 kΩ per Table 7.1). |
| 13 | ADDR | input | I²C address select that must not float: low gives address 0x44 and high gives 0x45; it must be grounded in 1-Wire mode. |
| 14 | NC | unconnected | No internal connection. |
| 15 | SCL | bidirectional | I²C clock line (I/O) that must not float; it must be grounded in 1-Wire mode and supports 100 kHz standard and 400 kHz fast mode. |
| 16 | NC | unconnected | No internal connection. |
| 17 | NC | unconnected | No internal connection. |
| 18 | NC | unconnected | No internal connection. |
| 19 | NC | unconnected | No internal connection. |
| 20 | VDD | power_in | Supply input; the datasheet specifies 2.0 V to 5.5 V operation (absolute maximum −0.3 V to 6 V). |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
