MT6620GA-STD from Magn Tek, in a TSSOP-24. 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 | PWM | output | Push-pull digital PWM output carrying the 12-bit absolute angle, with programmable frequency (125 Hz to 2 kHz) and polarity. |
| 2 | - | unconnected | Name, type and description are shown as '-' in the datasheet pin table (no function stated). |
| 3 | VCC | power_in | Power supply, 3.3 to 5.0 V (datasheet electrical conditions 3.0 to 5.5 V); a decoupling capacitor of at least 0.1 uF to ground is recommended. |
| 4 | - | unconnected | Name, type and description are shown as '-' in the datasheet pin table (no function stated). |
| 5 | - | unconnected | Name, type and description are shown as '-' in the datasheet pin table (no function stated). |
| 6 | - | unconnected | Name, type and description are shown as '-' in the datasheet pin table (no function stated). |
| 7 | - | unconnected | Name, type and description are shown as '-' in the datasheet pin table (no function stated). |
| 8 | VSS | power_in | Ground. |
| 9 | - | unconnected | Name, type and description are shown as '-' in the datasheet pin table (no function stated). |
| 10 | ENZ | input | Digital input that enables the target Z pulse and masks the extra Z pulses; when held high every magnetic pole pair outputs a Z pulse, otherwise no Z is output. |
| 11 | TEST_EN | input | Digital input for factory test, for MagnTek use only. |
| 12 | CAL_ENB | input | Digital input that enables calibration; pulling it low enters the self-calibration mode. |
| 13 | SDAT | bidirectional | Bidirectional SPI data line (3-wire SPI); high-impedance input except while the device drives output data. |
| 14 | SCK | input | SPI clock input driven by the host, held low when idle (minimum clock period 125 ns). |
| 15 | CSN | input | SPI chip select input; transfers start on the falling edge and end on the rising edge. |
| 16 | Z | output | Digital output for the incremental Z (zero) signal, with programmable width and position. |
| 17 | B | output | Digital output for the incremental B signal, quadrature with A. |
| 18 | A | output | Digital output for the incremental A signal, with programmable resolution of 1 to 2,500 pulses per pole pair. |
| 19 | STATUS | output | Digital output giving the signal amplitude as a 2 kHz PWM (10% to 33% duty cycle indicates a suitable magnetic field), and the self-calibration state during calibration. |
| 20 | ERROR | output | Digital output for the alarm (fault) information; it goes high on any diagnostic alarm and is low when there is none. |
| 21 | U | output | Digital output for the U signal of the UVW output (1 to 63 pole pairs programmable). |
| 22 | V | power_in | Digital output for the V signal of the UVW output, 120° from U. |
| 23 | W | output | Digital output for the W signal of the UVW output, 120° from V. |
| 24 | TEST | input | Digital input for factory test, for MagnTek use only. |
