MT6835GT-STD 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 inverted A output (-A) when configured for differential ABZ mode. Digital push-pull output, VOH ≥ VDD-0.4 V @ -2 mA, VOL ≤ 0.4 V @ 2 mA.
2	V	output	Incremental V-phase output (UVW mode) or inverted B output (-B) when configured for differential ABZ mode. Digital push-pull output.
3	W	output	Incremental W-phase output (UVW mode) or inverted Z output (-Z) when configured for differential ABZ mode. Digital push-pull output.
4	CAL_EN	input	Customer-side auto-calibration enable control pin. Digital input; VIH ≥ 0.8VDD, VIL ≤ 0.2VDD.
5	MISO	output	SPI data bus - master-in / slave-out. MT6835 drives data to the host MCU. Digital push-pull output.
6	MOSI	input	SPI data bus - master-out / slave-in. Data received by MT6835 from the host MCU. Digital input; VIH ≥ 0.8VDD, VIL ≤ 0.2VDD.
7	SCK	input	SPI serial clock input from the host MCU.
8	CSN	input	SPI chip-select / enable control input, active low.
9	VDD	power_in	Power supply input, 3.3-5.0 V typical (3.0-5.5 V absolute operating range). Supply current Idd ≈ 15-28 mA (22 mA typ).
10	OUT	output	PWM output carrying the 12-bit absolute angle (and optional velocity) data. Programmable frequency ~497 Hz or 994 Hz (±8%). Digital push-pull output.
11	TEST	input	Factory test pin (analog input). For MagnTek internal use only; leave unconnected or per manufacturer guidance.
12	VSS	power_in	Ground (0 V) reference for the chip.
13	TEST_EN	input	Factory test enable pin (digital input). For MagnTek internal use only; must be left inactive in customer applications.
14	Z	output	Incremental encoder Z (index) output. Digital push-pull output; VOH ≥ VDD-0.4 V @ -2 mA, VOL ≤ 0.4 V @ 2 mA.
15	B	output	Incremental encoder B-channel output. Digital push-pull output; programmable resolution 1-16,384 pulses per revolution.
16	A	output	Incremental encoder A-channel output. Digital push-pull output; programmable resolution 1-16,384 pulses per revolution, max frequency 2.048 MHz.
