NEW SURFACE-MOUNT FULLY INTEGRATED CURRENT SENSORS

The ACS772/3 family expands to include through-hole and surface-mount CB package options with enhanced working isolation voltage

NEW SURFACE-MOUNT FULLY INTEGRATED CURRENT SENSORS

Allegro MicroSystems, a global leader in power and sensing solutions for motion control and energy efficient systems, today announced significant ease-of-use enhancements to its popular high current fully integratedĀ ACS772/3Ā current sensor ā€œCBā€ package family.

These industry-leading, automotive grade high voltage isolation current sensors already provide economical and precise solutions for both AC and DC current sensing up to 400A. Building on that leadership and deep customer-understanding, Allegroā€™s new surface-mount leadform option for the CB package is the answer to many customer challenges by providing a flexible solution for space constrained applications.

ā€œThis is a classic, ā€˜You asked ā€“ we listened.ā€™ Ā innovation with purpose moment for us,ā€ explains Shaun Milano, Business Unit Director for Current Sensors. ā€œOur customers want flexibility, and weā€™re excited to provide these innovative, robust solutions in this new surface-mount option to complement our highly popular through-hole version.Ā High current PCB designs improve power density and efficiency and this surface-mount option allows customers to realize these advantages with a simpler manufacturing process.ā€

TheĀ ACS772/3Ā family of current sensor ICs has an enhanced feature set that helps engineers simplify their bill of materials and improve efficiency in the toughest of applications:

  • Small form footprint over competing solutions
  • Very fast 2.5uSĀ response time that enables overcurrent fault detection ā€“ ideal for safety-critical applications
  • Enhanced working isolation voltages up to 1300V+ for basic DC voltage, and 650V+ for reinforced isolation DC voltage ā€“ No need for opto-isolators or other costly isolation techniques.
  • High accuracy of +/-2.1% over the lifetime of the IC

These features make theĀ ACS772/3Ā family ideal for a range of applications from industrial robotics to electric vehicles.
