The AK7452 integrates an advanced user calibration function, enabling it to correct angular errors caused by mounting misalignment, magnet characteristics, etc.  In addition, supported are Shaft-end detection and detection on an orthogonal side of the shaft (Off-Axis).
The capability of ABZ phase output resolution any setting from 1 to 4096 types enhances motor control usability even in DC brushless motors or stepping motors.

● Supporting programmable ABZ/UVW output

A zero point setting can set any angular position to 0 degree.  Rotation direction, resolution of ABZ output, (1 to 4096), and number of pulses of UVW output (1 to 32), can be programmed to the internal EEPROM.

The AK7451 is able to output up to eight-pole UVW phase that improves versatility, realizing rotor position detection in DC brushless motor-driven operation without Hall ICs installation.  The expansion of ABZ phase output resolution setting from 4 to 16 types enhances motor control usability.  These key features enable to use for more various types of industrial equipment motors than conventional products.
● Easy installation of a contactless rotary sensor with diametrically magnetized mono-pole magnets
● Supporting High-speed rotational operation
● Programmable ABZ/UVW phase output

The automotive qualified AK740X product family comprises the 12-bit angle sensor AK7401 with serial/PWM interface as well as the high speed 12-bit angle sensor AK7405 with serial / ABZ interface.  AK7401 is suitable for the rotational position sensing application, for example steering angle measurement, valve position sensing and so on.  AK7405 is suitable for high rotational application just as motor control.
