Features for the HALL-TRIGGER-EVM
- Up to 10 mm of trigger displacement translated to voltage
- Measured voltage error <3% without calibration and <0.5% with calibration
- (Optional) disables voltage output when strong external magnetic fields are detected
- Operates from AAA batteries or 5-30 V external power supply
- Low system current consumption in sleep mode (3.5-6.9 µA, depending on selected protection level against external magnetic fields)
Description for the HALL-TRIGGER-EVM
This evaluation module (EVM) uses Hall-effect sensors to implement a trigger that outputs a varying voltage based on how far the trigger is pressed. The EVM uses a contactless approach that reduces wear and tear compared to traditional mechanical-based triggers, thereby improving product lifetime. Low-power Hall-effect switches are used along with a load switch to keep the system in a low power standby mode when the trigger is not pressed. In addition, an optional magnetic field protection feature is available that disables the voltage output when a strong, external magnetic field is present.
