KTH7823-X-N-QN16 from CONNTEK, in a QFN-16L(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 | SSD | output | SSI data output; carries the SSI angle data stream read by the external SSI master. |
| 2 | A | output | ABZ incremental A-phase output; the A and B edges lead or lag by 1/4 cycle to indicate rotation direction, with maximum ABZ output frequency of 16 MHz at the default ABZLIMIT setting. |
| 3 | Z | output | ABZ incremental Z (index/zero) output; one rising edge per revolution at the zero position, with width and phase programmable via ZL(1:0) and ZD(1:0). |
| 4 | MOSI | input | SPI data line listed in the datasheet as the SPI host data output, with an internal weak pull-up; the datasheet recommends holding MOSI low during angle transfers to avoid spurious data. |
| 5 | CS | input | SPI chip select with an internal weak pull-up; pulling it low starts an SPI transaction and the sensor prepares data into its output buffer. |
| 6 | B | output | ABZ incremental B-phase output; leads A by 1/4 cycle when rotating counter-clockwise and follows A when rotating clockwise (default RD=1). |
| 7 | MISO | output | SPI slave data output that returns the angle or register data to the host, with data valid within 50 ns (TDV) under the 20 pF load condition. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | PWM | output | Single-wire 14-bit absolute angle PWM output; the default output form of pin 9, with duty cycle proportional to magnetic field angle at 910 Hz PWM frequency. |
| 10 | TEST | passive | Factory test pin that must be connected directly to GND in use on the QFN-16L package. |
| 11 | MGL | output | Magnetic field strength too-low alarm output, driven by the mgl(2:0) threshold setting (for example, goes high when field falls below 18 mT at mgl=0). |
| 12 | SCLK | input | SPI clock input with an internal weak pull-up, using SPI mode 3 (CPOL=1, CPHA=1) with a minimum clock period of 100 ns. |
| 13 | VDD | power_in | Supply input; the device operates from 3.0 V to 3.6 V (3.3 V nominal) or 4.5 V to 5.5 V (5 V nominal). |
| 14 | NC | unconnected | Not connected. |
| 15 | SSCK | input | SSI data clock input with an internal weak pull-down; the host raises SSCK to trigger a read, with SSCK period between 0.66 µs and 16 µs. |
| 16 | MGH | output | Magnetic field strength too-high alarm output, driven by the mgh(2:0) threshold setting (for example, goes high when field exceeds 23 mT at mgh=0 and mgh=7 default at 103 mT). |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
