About this item

The 7Semi ACS772 is an automotive-grade current sensor designed for high-precision, high-voltage applications. It offers a wide current sensing range from 50A to 400A with a 200kHz bandwidth, ensuring accurate measurements in dynamic systems. Operating on a 5V supply, the sensor provides a linear analog output proportional to AC or DC currents. Key features include a low 100µΩ internal conductor resistance for minimal power loss, reinforced galvanic isolation for safe high-side current sensing, and a fast 2.5µs response time for overcurrent fault detection. Factory-trimmed gain and offset ensure optimal accuracy over a wide temperature range. Applications encompass motor control, power supplies, inverters, and overcurrent protection systems.
