MT6825GT-EED from Magn Tek, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	U	output	Incremental U-phase output (UVW mode) or complementary -A output (ABZ differential mode). Push-pull digital output, VOH = VDD-0.25 V @ 2 mA, VOL = 0.25 V. Function selected by internal register / factory configuration.
2	V	output	Incremental V-phase output (UVW mode) or complementary -B output (ABZ differential mode). Push-pull digital output.
3	W	output	Incremental W-phase output (UVW mode) or complementary -Z output (ABZ differential mode). Push-pull digital output.
4	HVPP	power_in	MTP (multi-time-programmable EPROM) programming supply. Requires 7.0-7.2 V (max 8 V abs) only during MTP programming; tie directly to GND in normal operation. Reference circuit uses 1 µF to GND when the MTP programming interface is provided.
5	MISO	output	SPI data line, slave-out/master-in. Active in 4-wire SPI mode; unused (leave floating or tie appropriately) in 3-wire SPI mode where MOSI/SDAT becomes bidirectional.
6	MOSI/SDAT	bidirectional	SPI data line. In 4-wire SPI this is MOSI (master-out/slave-in, input); in 3-wire SPI this becomes SDAT, a bidirectional data pin used for both command and readback.
7	SCK	input	SPI clock input. Digital input with VIH ≥ 0.7·VDD, VIL ≤ 0.3·VDD.
8	CSN	input	SPI chip-select (active low). Has an internal pull-down (ILK spec references CSN internal pull-down resistor).
9	VDD	power_in	Main supply, 3.0-5.5 V (typical 3.3-5.0 V). Absolute max 6.5 V. Supply current Idd typ 10 mA, max 15 mA. Decouple with 0.1 µF and TVS(6 V) per reference circuit.
10	OUT	output	12-bit absolute angle PWM output. Programmable frequency, typ 971.1 Hz or 485.6 Hz (±8%), rise/fall ≤ 1 µs into 1 nF load. Available simultaneously with ABZ/UVW/SPI.
11	TEST	input	Factory test pin, for MagnTek internal use only. Leave unconnected (or tie to GND) in customer applications.
12	VSS	power_in	Ground reference (0 V).
13	ERROR	output	Error/alarm interrupt output. Asserts on internal error detection (e.g. magnetic-field out-of-range). Push-pull digital output.
14	Z	output	Incremental Z index output; one pulse per mechanical revolution marking the 0° reference. Programmable pulse width (1, 2, 4, 8, 12, 16 LSB or 180°) and programmable zero position.
15	B	output	Incremental quadrature B output. Programmable 1-4096 pulses/rev; on -EED variant factory-set to 4096 PPR. B leads/lags A depending on rotation direction and ROT_DIR register.
16	A	output	Incremental quadrature A output. Programmable 1-4096 pulses/rev (4096 on -EED). Maximum A/B frequency 1.024 MHz (INL degrades above 2 MHz).
