Internal integration: Voltage stabilizing circuit, Hall element, signal amplifier, Schmitt trigger, NMOS open-drain output transistor
Certifications: AEC-Q100 automotive grade, RoHS environmental protection, high ESD/EMC anti-interference, reverse battery protection
II. Core Electrical Parameters (25℃ standard operating condition)
1. Power Supply Electrical Characteristics Table
Parameters Specification Values
Operating supply voltage VCC 3.8 V ~ 24 V DC (compatible with 5V/12V/24V industrial control / automotive power supply)
Maximum withstand voltage ±30V (built-in reverse connection protection and surge protection)
Typical static operating current 7.5 mA
Power-on startup time ≤ 4 μs, magnetic field can be detected immediately upon power-on
2. Magnetic field triggering parameters (core magnetic performance) Table
Parameters Typical Value Explanation
Work Trigger Point BOP (S pole close) 175Gs (17.5 mT) Output is pulled low and conducts when the magnetic field is ≥ 175Gs
Release Point BRP (magnet far away) 45Gs (4.5 mT) Output is cut off and has high resistance when the magnetic field is < 45Gs
Magnetic Hysteresis Window BHYS 130Gs Prevents magnetic field jitter from triggering incorrectly
Detection Polarity Single pole, only responds to the S pole of the magnet N pole has no response
3. Output Parameters
Output Structure: N-channel open-drain (open collector), must use an upper pull-up resistor
Maximum Sinking Current IOUT: 25 mA, can directly drive LEDs, small relays
Saturation Drop (conduction at 20mA): Typical 215 mV, maximum 400 mV
Off-state Leakage Current: ≤ 10 μA
4. Environment and Temperature
Operating Temperature: -40 ℃ ~ +85 ℃ (vehicle-grade wide temperature range)
Storage Temperature: -55 ℃ ~ +150 ℃
Package Material: Black epoxy resin plastic packaging, resistant to vibration and moisture
