A3144E TO-92S Hall Switch Sensor

Description

A3144E TO-92S Hall Switch Sensor The 3144 is a high-sensitivity Hall effect switch. Ideal for a variety of applications, this sensor integrates a power reverse protection circuit, internal voltage regulator, Hall voltage generator, differential amplifier, Schmitt trigger, and an open collector output stage. It converts magnetic induction intensity into a digital voltage signal, making it perfect for use with rectangular or cylindrical magnets. Available in a TO-92S package, it operates across a wide temperature range of -40°C to 125°C and supports supply voltages from 2.5V to 24V with a load current capacity of up to 50mA. Its halogen-free design ensures environmental friendliness and reliability. Features Advanced DMOS process for superior performance Reverse bias protection on power supply pins Wide supply voltage range (2.5V to 24V) with high output current up to 50mA 100% tested at 125°C for temperature reliability Fast switching speed with no momentary jitter High bandwidth up to 100kHz High transient voltage protection Excellent ESD static performance (>4kV) Long lifespan, compact size, and easy installation Specifications Parameter Range Unit Supply Voltage (VDD) 2.5 to 24.0 V Supply Current (IDD) 2.5 to 5.0 mA Output Saturation Voltage (Vsat) Max 400 mV Output Leakage Current (Ioff) Max 10 µA Output Rise Time (TR) 0.04 to 0.45 µs Output Fall Time (TF) 0.18 to 0.45 µs Conversion Frequency (Fbw) Max 100 kHz Opening Point (BOP) 60 to 100 Gauss Closing Point (BRP) 40 to 80 Gauss Hysteresis (BHYS) 20 Gauss Electrostatic Protection (ESD) 4000 V Limit Supply Voltage -28 to 28 V Limit Output Voltage 0.5 to 24 V Limit Output Current 50 mA Operating Temperature -40 to 125 °C Storage Temperature -55 to 165 °C ESD Rating 4000 V Applications DC brushless motor control Contactless switches Position control Current sensing Safety alarm systems Device isolation detection Rotation speed detection DataSheet 3144 Datasheet en-US
