Allegro MicroSystems now offers significant ease-of-use enhancements to its high current fully integrated ACS772/3 current sensor 'CB' package family.
These automotive-grade high voltage isolation current sensors currently offer economical and precise solutions for both AC and DC current sensing up to 400A. Building on that the company’s new surface-mount lead form option for the CB package is the answer to many customer challenges by offering a flexible solution for space-constrained applications.
“This is a classic, ‘you asked – we listened’ innovation with purpose moment for us,” explains Shaun Milano, business unit director for Current Sensors. “Our customers want flexibility, and we’re excited to provide these innovative, robust solutions in this new surface-mount option to complement our highly popular through-hole version. High current PCB designs improve power density and efficiency, and this surface-mount option allows customers to realise these advantages with a simpler manufacturing process.”
The family of current sensor ICs provides an enhanced feature set that assists engineers in simplifying their bill of materials and improve efficiency in the toughest of applications.
“Many of our customers, especially in green energy applications, are looking for higher working voltages which can provide efficiency improvements and cost reductions in their systems,” said Milano. “In solar applications, for instance, raising the system voltage allows for longer strings, which eliminates significant wiring and connector combiner boxes. It also allows for longer panel strings with higher rated output inverters, which reduces losses and improves efficiency. These improvements are a win-win for our customers.”
