  1. Orderable Part Number: Within the product family there exists a variety of sensitivity options and package variants. Each of these options is selected from and used to run a simulation. The location of the sensing element within the package is accounted for automatically. TI recommends referring to the product data sheet for exact sensor locations when configuring simulations. Please refer to Section A.1 for more details setting the sensor origin.
  2. Applied Vcc: For latches and switches the output is binary and typically consists of either a push-pull type or requires a pull-up resistor. In cases where a pull-up is required (open-drain), the output is shown to toggle between the output logic low voltage, VOL and Vcc. If the output format is push-pull then the upper limit is output logic high voltage VOH.
  3. Select BOP: BOP is defined as the operating threshold field. The output switches to an active output state when the input field exceeds this value. TI recommends setting this field to the High Value (BOP Max in the data sheet) to verify that even the highest threshold setting is met during operating conditions.
  4. Select BRP: BRP is defined as the release threshold field. The output is released from the active output state when the input field is below this value. TI recommends setting this field to Low Value (BRP Min in the data sheet)to verify that the lowest release threshold is met.
