Micronas – HAL15xy SOT23 Multi-Purpose Switch Family
HAL15xy Automotive Sensor:
Fulfilling latest quality and functional safety standards as AEC-Q100 qualified and ISO 26262 compliant sensor solution.
Optimal system solution for:
- Position detection, as for
- Seat and pedal position
- Gear shift lever
- Seat belt presence detection
- Index counting, as for
- Window lifter
- Brushless DC motor commutation
Also an industrial version is planned
HAL15xy at a glance:
Multi-purpose devices, available as 3-wire version with short-circuit protected open-drain output and as 2-wire version with current out-put, targeting a wide range of applications by providing new feature set including power-on reset, thermal shutdown and power-on self-test at an excellent price-feature-ratio.
ISO26262 compliant:
Functional Safety – ASIL A ready device:
- Development process and technical realization according to ISO 26262
- Single Point Fault Metric of device ≥ 60% (failure coverage)
- Internal diagnoses of important functions
- Fail safe state is tri-state (high impedance) for 3-wire and low-current level for 2-wire
- Supervision of:
- Internal voltage regulator: under and overvoltage detection
- Monitoring of internal bias and current level
- Monitoring band gap
- Monitoring of hall plate voltage
- Power-on self-test checking full sensor signal path
- Device is ready for ASIL A applications or higher classified applications by decomposition
