Applications

Automotive Current Monitoring: The ACS758 is ideal for monitoring current in automotive applications, such as battery management systems, motor control, and power distribution. Its Hall-effect-based open-loop design ensures accurate current sensing up to 50A, while its AEC-Q100 compliance makes it suitable for harsh automotive environments. The ratiometric voltage output and fast response time (4µs) enable real-time monitoring and control of electrical systems in vehicles.
Industrial Motor Control: The ACS758 is well-suited for industrial motor control applications, where precise current sensing is critical for efficient operation and protection. Its unidirectional current sensing capability, combined with high accuracy (±2%) and linearity (±1%), ensures reliable performance in variable frequency drives (VFDs) and servo motor controllers. The wide operating temperature range (-40°C to 150°C) allows it to function in demanding industrial environments.
Power Supply Monitoring: The ACS758 can be used in power supply units (PSUs) to monitor and regulate current flow, ensuring stable and efficient power delivery. Its Hall-effect sensor provides galvanic isolation, eliminating the need for shunt resistors and reducing power losses. The 3V to 5.5V supply voltage range and low current consumption (max 13.5mA) make it suitable for both low-power and high-power applications, including switch-mode power supplies and uninterruptible power supplies (UPS).
Renewable Energy Systems: The ACS758 is an excellent choice for current sensing in renewable energy systems, such as solar inverters and wind turbine controllers. Its ability to measure DC currents up to 50A with high accuracy (±2%) and fast response time (4µs) ensures efficient energy conversion and system protection. The through-hole mounting and robust package (5-CB Formed Leads, PFF) make it durable and reliable in outdoor and high-vibration environments.
These applications highlight the versatility and reliability of the ACS758 in various industries, leveraging its advanced Hall-effect technology and robust design for precise current sensing and monitoring.
