49E Linear Hall Effect Sensor for E-bike Throttle Grip, Speed Sensor, Accelerator Sensor

Description & Working Principle

The 49E integrates a Hall sensing element, a voltage regulator, dynamic offset cancellation circuitry, a temperature compensation system, and a linear output amplifier directly onto a single silicon chip.

1. Zero Magnetic Field: When no magnetic field is present, the output sits at roughly half the supply voltage (VCC/ 2 = 2.5V when powered by 5V).

2. South Magnetic Pole: Bringing a South pole close to the branded front face increases the output voltage towards Vcc (up to ~4.2V max).

3. North Magnetic Pole: Bringing a North pole close to the branded front face decreases the output voltage towards Ground (down to ~0.8V min).
