You can use useful simulation or calculation tools for your design.

Please note that you are required to register your information when using some of those tools.

Coreless current sensor IC Thermal Simulation Tool

Currentier, AKM's current sensor, has very low heat generation and it makes it possible to reduce the heat generation of current sensing area by replacing from shunt / cement resistors. You can compare the temperature rise of Currentier and shunt / cement resistance with this tool.
Please use it for your product consideration.

Input / Output Characteristics Check Tool

This tool allows you to easily calculate output voltage based on input current or input current based on output voltage. You can use it to check the input/output characteristics of each product.

Motor Error Calculation Tool

You can use servo information and current sensor information to estimate how much torque accuracy would improve if you switched from your present current detection method to detection using a Currentier. This is useful for solving servo accuracy problems.

(* You must register "myAKM" to use these services.)

Creepage / Clearance distance Calculation tool

You can calculate how much creepage and clearance distance are necessary for your environment. This is useful for improving the safety of applications that require insulation.

Overcurrent Detection Configuration Tool

You can select products with overcurrent detection functions and calculate REF voltages for setting thresholds. This helps to improve safety in applications where overcurrent detection is required. (This simulation is for the CZ3A series.)
