Hall Sensor Switch Point Calculator
Apply caller unipolar Hall Schmitt thresholds to actual ordered field samples with initial state and transition witnesses; unlike hysteresis-width scalar, tracks state. No bipolar-device inference or switch identification.
Description
A Hall Schmitt switch keeps state between operate and release thresholds.
A Hall Schmitt switch keeps state between operate and release thresholds. Initial state therefore matters.1
Enter finite ordered field samples, finite release<operate thresholds and initial boolean. Return binary state history and zero-based operate/release witness indexes; empty samples are allowed.
When to use Hall Sensor Switch Point Calculator
Use Hall Sensor Switch Point Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No bipolar/latching-device model or switch identification is inferred.
Prepare measured device or circuit evidence with matched frequency, temperature, waveform and calibration conditions. Supply explicit caller ratings and limits.
How to use Hall Sensor Switch Point Calculator and understand its results
- Prepare measured device or circuit evidence with matched frequency, temperature, waveform and calibration conditions. Supply explicit caller ratings and limits.
- Enter observedFieldMillitesla, callerOperateMillitesla, callerReleaseMillitesla, initialSwitchActive using the field table and calculation rules, then run the tool.
- Read modeledSwitchActiveFlags, modeledOperateSampleIndices, modeledReleaseSampleIndices. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| observedFieldMillitesla | Observed field millitesla | list of number | Required |
| callerOperateMillitesla | Caller operate millitesla | number | Required |
| callerReleaseMillitesla | Caller release millitesla | number | Required |
| initialSwitchActive | Initial switch active | boolean | Required |
Enter finite ordered field samples, finite release<operate thresholds and initial boolean. Return binary state history and zero-based operate/release witness indexes; empty samples are allowed.
inactive turns on at field≥operate; active turns off at field≤release Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| modeledSwitchActiveFlags | Modeled switch active flags | list of number |
| modeledOperateSampleIndices | Modeled operate sample indices | list of number |
| modeledReleaseSampleIndices | Modeled release sample indices | list of number |

}Limitations and assumptions
No bipolar/latching-device model or switch identification is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Thyristor Latching Current Calculator: Thyristor latching depends on anode current when gate drive ends. Gate-rating evidence is a separate necessary input. For a complementary task, use Latchup Holding Voltage Calculator: A descending latchup sweep can bracket a release threshold between samples. Subsample voltage should not be invented.
