KTH5701AQ3QNS

CONNTEK · 3D Magnetic Sensors · QFN-16L-EP(3x3)

KTH5701AQ3QNS from CONNTEK, in a QFN-16L-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 INT output Data-ready or wake-up & sleep mode interrupt output, set to 1 until the host sends a read command and reads back the measurement data.
2 CS input Active-low SPI chip select driven by the SPI master; pulled up to VDD_IO in I2C mode.
3 SCL/SCLK input I2C or SPI clock signal input.
4 NC unconnected Not listed in the pin table, so covered by the 'Other NC' entry; not connected, and grounding all NC pins is recommended.
5 SDA/MOSI bidirectional I2C data input/output port, or SPI data from master output to slave input.
6 MISO output SPI data from slave output to master input; short MISO and MOSI when using only the three-pin SPI data transfer.
7 BUTT_OUT/TRIG bidirectional Push-button function output or single-measurement trigger input; must be connected to ground when not used, and must not float when used as a trigger.
8 VDD_IO power_in IO power supply, recommended operating range 1.8 V to VDD.
9 NC unconnected Not listed in the pin table, so covered by the 'Other NC' entry; not connected, and grounding all NC pins is recommended.
10 NC unconnected Not listed in the pin table, so covered by the 'Other NC' entry; not connected, and grounding all NC pins is recommended.
11 A1 input I2C address input A1; must be connected to ground in SPI communication.
12 A0 input I2C address input A0; must be connected to ground in SPI communication.
13 VSS power_in Ground.
14 NC unconnected Not listed in the pin table, so covered by the 'Other NC' entry; not connected, and grounding all NC pins is recommended.
15 VDD power_in Power supply, recommended operating range 2.8 V to 5.5 V (3.3 V typical), absolute maximum 6 V.
16 NC unconnected Not listed in the pin table, so covered by the 'Other NC' entry; not connected, and grounding all NC pins is recommended.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
