1Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions, such as TA = 25°C and VCC =
12 V. Performance may vary for individual units, within the specified maximum and minimum limits.
2Maximum voltage must be adjusted for power dissipation and junction temperature.
31 G (gauss) = 0.1 mT (millitesla).
3BOP = operate point (output turns off); BRP = release point (output turns on).
