Device and method for kickback protection

A device for confirming kickback, the device comprising:

• an inertial measurement unit (IMU);
• and
• a finite state machine configured to:
• compare one or more outputs from the IMU to a predetermined IMU threshold;
• when any one of the one or more outputs from the IMU is greater than the predetermined IMU threshold for a first predetermined amount of time, compare an input current to a predetermined current threshold;
• when the input current is greater than the predetermined current threshold for a second predetermined amount of time, generate a kickback interrupt signal;
• when the input current is not greater than the predetermined current threshold, compare an input voltage to a predetermined voltage threshold;
• when the input voltage is less than the predetermined voltage threshold for a third predetermined amount of time;
• generate a kickback interrupt signal;
• and
• when the input voltage is not less than the predetermined voltage threshold for the third predetermined amount of time and the input current is not greater than the predetermined current threshold for the second predetermined amount of time, generate a false positive (FP) signal.
