Single-chip solution simplifies industrial and home automation applications

Allegro MicroSystems has released the ACS37800, a Hall-effect power monitoring IC for single-phase AC and DC solutions in a small PCB footprint. Another industry-first innovation, the company's device is an integrated power monitoring chip that permits simultaneous measurement of power, voltage, and current for AC and DC signals with an isolation rating of up to 1480Vpk in a small SOIC16W package, lowering the solution BOM size, cost and complexity.

"Our newest power monitoring chip is a gamechanger for IoT devices, smart lighting, data centres, and telecom applications, in particular," says Shaun Milano, business unit director for Current Sensors at Allegro. "We’ve improved on our first-generation integrated solution by adding the ability to measure voltage, current and power in AC as well as DC at the same time – and with reinforced isolation, our customers can eliminate many expensive components on their PCBs. The ACS37800 dramatically simplifies measuring power in a unique single-chip solution."

The new device permits devices to easily track power consumption and to optimise energy usage by detecting decreased power efficiency for predictive maintenance. This makes it ideal for motor control, building automation, and various green industrial applications.
