Hall Current Sensor ACS758LCB-050B

High-Precision Monolithic Hall IC: Powered by Allegro’s ACS758LCB-050B Hall-effect current sensor IC, delivering accurate bi-directional current measurement up to ± 50A.

Galvanic Isolation Protection: Features 100 kV galvanic isolation between the primary conductor path and low-voltage control circuits, ensuring maximum safety for host microcontrollers.

Low Primary Conductor Resistance: Built with a ultra-low 100 µΩ internal conductor resistance path to minimize power dissipation, thermal loss, and voltage drops across high-current lines.

Factory-Calibrated Sensitivity: Calibrated to an internal sensitivity rating of 40 mV/A with low thermal drift, outputting a precise analog voltage scaled directly around a V_CC/2 zero-current offset point.

Integrated Filtering & Noise Suppression: Equipped with onboard filtering components and a low-noise analog signal path for stable current tracking in high-power switching environments.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with heavy-duty primary current terminal pads, onboard ACS758 IC, and gold/tin-plated header pins.

Technical Specifications:

Operating Supply Voltage (V_CC): 3.0V - 5.5V DC (5.0V nominal).

Current Measurement Range: $\pm 50A AC or DC.

Sensitivity Rating: 40 mV/A (at 5V supply).

Internal Conductor Resistance: 100 µΩ typical.

Color: Purple PCB with Black Sensor Module and Gold/Silver Pin Contacts.

Usage Advice: Solder high-current load wires directly to the heavy primary terminal pads; connect VCC (5V), GND, and OUT pins to your microcontroller ADC for real-time current calculation.

Maintenance: Keep primary high-power connections securely soldered; store in anti-static packaging and keep the board clean, dry, and free of conductive debris.

Essential Heavy-Duty Current Sensor: Position as a top-grade current transducer for high-capacity motor speed controllers, solar inverter battery banks, industrial power supplies, and electric vehicle battery systems.

Highlight High Galvanic Isolation & Low Resistance: Emphasize how 100 µΩ ultra-low conductor resistance and built-in isolation protect sensitive microcontrollers while handling heavy continuous current loads without overheating.

Recommended Cross-Sell Add-ons: Pair with ACS712T 20A Range Current Sensor, WCS1500 Hall Effect Base Linear Current Sensor, INA226 IIC Bidirectional current sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
