System Electrical Characteristics and Temperature Range

1. For typical magnetic field (60mT) excluding current delivered to the external load and tolerance on polling times.
2. For OTP burn procedure the supply line source resistance should not exceed 1Ohm.

All limits are guaranteed. The parameters with minimum and maximum values are guaranteed with production tests or SQC (Statistical Quality Control) methods.

Figure 5: Absolute Maximum Ratings

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under Operating Conditions is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
