Explanation of Error Specifications for Allegro Linear Hall-Effect based Current Sensor ICs

AN296181 - Determining the accuracy of a system requires knowledge of the error introduced by each component. When looking at Allegro current sensor datasheets, the total error line item is a good approximation of the worst-case error seen in application.

Application Note

Overcurrent Fault Detection Using ACS37610 Coreless Current Sensor

AN269241 - This application note explains how the Overcurrent-Fault (OCF) feature of Allegro ACS37610 device can be used in application to reliably detect overcurrent conditions and how it can be configured to optimize accuracy and cover different application needs.

Application Note

Side-Shaft Positioning of Magnetic Angle Sensors

AN296179 - If a magnetic angle sensor is used in a side-shaft application with a diametral magnet, the sensor angle output is typically non-linear. Take a look at the two ways this issue can be addressed and the empiric formula to calculate the best possible side-shaft sensor position(s) to obtain a linear sensor output.
