Current-Sensor-ICs
Low Noise, Standalone, Coreless and Contactless Current Sensor with Overcurrent and Overtemperature Detection
ACS37610-1
The Allegro ACS37610/1 current sensors are a game changer for high current sensing applications, eliminating the need for bulky external cores or shields. They are designed to accurately measure both AC and DC current flowing through busbars or PCBs, making them ideal for a wide range of applications. The ACS37611 provides an improved sensitivity error over temperature. The SIP package simplifies through-busbar assembly and offers great immunity to displacement errors.
