MT6701

Description:

MT6701 is a new generation of magnetic Angle encoder chip based on differential Hall induction principle. MT6701 senses the component of the magnetic field perpendicular to the chip surface, and with the rotation of a pair of magnetic radial magnets on the chip surface,

The MT6701 corresponding output Angle signal of 0~360°. In addition to providing ABZ/UVW incremental output and Analog/PWM absolute Angle output, the MT6701 provides 14 bit digital Angle output via the I2C/SSI interface. In addition to rotation Angle measurement, the MT6701 also offers a "push" output to enable single-chip button (rotation + press) functionality.

Features:

- Based on differential Hall technology, absolute Angle measurement from 0° to 360° is provided

- Operating voltage 3.3~5.0V, operating temperature -40℃~125℃

- Typical linearity deviation <±1°, <±1.5° over the whole temperature range

- System delay is as low as 5us and can support speeds up to 55,000 RPM

- Provides I²C/SSI interface to read 14-bit Angle data inside the chip

- Incremental output ABZ supports any resolution of 1 to 1024 lines

- Incremental output The UVW supports any polarity from 1 to 16

- Provides 12-bit PWM output or analog output (12-bit DAC)

- Dedicated press detection output (sensing changes in magnet and chip spacing) for single-chip button applications

- Built-in EEPROM, >1000 iterations of programming

Instructions for use.

P1 is three-wire SPI bus

P2 for PWM, IIF and other signal output.

The chip's DATA line needs to send data as well as receive data, so it is recommended to use software to simulate SPI timing.

The MT6816 magnetic encoder chip is a new-generation high-speed, high-precision angle encoder chip. It is primarily used in brushless DC motor control, servo motor control, and closed-loop stepper motor control. Because the chip only responds to changes in the direction of a magnetic field parallel to the chip surface, the MT6816 has low tolerances for machining errors in the magnet itself and the distance between the magnet and the chip.

The MT6816 has a wide operating temperature range, operating from -40°C to 125°C, significantly broadening its application scenarios. The MT6816 provides an incremental ABZ output interface to replace traditional photoelectric encoders, with a maximum resolution of 1024 pulses/revolution or 4096 steps/revolution. It also provides incremental UVW signals, programmable from 1 to 16 pole pairs, to replace Hall effects.

The MT6816 provides a 3-wire or 4-wire SPI interface for a host computer or MCU to read the chip's internal 14-bit absolute angle value. A single-wire PWM output also provides 12-bit absolute angle data.

Features and Benefits

Based on advanced AMR anisotropic magnetoresistive technology, it provides 0-360° absolute angle position detection.

Outputs 14-bit absolute angle data resolution.

Supports speeds up to 25,000 RPM.

System latency for angle output is <2 µs.

Operates in a temperature range of -40°C to 125°C.

Supports incremental ABZ, incremental UVW, PWM absolute value, and SPI bus outputs.

Incremental ABZ outputs support 1 to 1024 pulses/revolution, with user-programmable integer resolution.

Incremental UVW outputs support 1 to 16 pole pairs, with user-programmable integer pole pairs.

This module is used in conjunction with magnetic objects, and indirectly controls the suction and release of relays by sensing magnetic fields through Hall sensors, achieving the control of AC and DC high-power equipment through magnetic fields. Such as door magnetic, window magnetic, magnetic control detection, etc.

Electrical parameters:

1. Working voltage: 5-24VDC

2. Output form: relay normally open or normally closed 250VAC 10A/30VDC 10A

3. Hall element: 3144E

4. Size: 3mm mounting hole, sensor probe small plate 2mm mounting hole

Usage:

Insert the Hall sensor probe and provide power. Hall sensors need to be used in conjunction with magnets. When a certain amount of magnetic force is detected, the relay is engaged, and the common end COM and normally closed end NO are connected. When no magnetic force is detected, the relay is released, and the common end COM and normally closed end NC are connected; A relay is like a physical switch, with no voltage at both ends of the switch. It needs to be connected in series with the controlled equipment and then connected to the power supply to achieve switch like control.

The sensor probe small board can be disassembled and soldered off, and the Hall element of the plug-in can be replaced by welding it in the solder pad hole next to it.
