Description
The AK7454 is a 14-bit rotation angle sensor that detects a magnetic field parallel to the IC surface and follows high-speed rotation up to 25,000 rpm using our proprietary technology. With the simple configuration of the AK7454 and a small magnet, the rotation angle can be detected without contact. The power supply voltage is from 3.0V to 5.5V and a small package (QFN 24-pin) is used.
Key Features
Angle error correction function The AK7454 has an angle error correction function, which enables high-precision correction with at least 16 points of measurement data per round. By writing the angle error correction parameters to the AK7454's built-in EEPROM, highly accurate angle detection is realized.
Off-Axis placement support In addition to the shaft end (Shaft-End) arrangement, it corresponds to the Off-Axis arrangement where ICs are arranged next to the two-pole magnetized magnet, so that a through-axis motor system can be configured. As a result, the motor system can be made thinner and hollow.
Various parameter setting by built-in EEPROM It is possible to set the zero point that can set any angular position to 0 °, the rotation direction, the ABZ output resolution (any value from 1 to 4096ppr), and the number of UVW poles (any value from 1 to 32 pole pairs). The Z-phase output width and phase can be set freely, and the zero point of ABZ / UVW can be set independently, improving the convenience of motor control.
Applications
Compact absolute rotary encoder, Compact input device (mode selector, control volume) Substitute for potentiometer, Rotary switch
