With 10-MHz bandwidth and 50-ns response time, Allegro’s ACS37100 XtremeSense tunneling magnetoresistance (TMR) present sensor allows exact present measurement. It’s designed for power-conversion techniques utilizing fast-switching GaN and SiC FETs, together with EV chargers, photo voltaic string inverters, and server energy provides.
At sub-MHz frequencies, standard magnetic sensors typically lack the pace and accuracy wanted for steady management and safety loops. The ACS37100 overcomes these limits with its excessive bandwidth and quick response, offering the high-fidelity present suggestions important for high-speed switching management.
Utilizing XtremeSense TMR expertise, the ACS37100 maintains a low noise degree of 26 mA RMS throughout the complete DC to 10‑MHz bandwidth, with ±2% sensitivity error over temperature. A voltage reference output helps differential routing in noisy environments, whereas a fault output offers an adjustable threshold for quick open-drain overcurrent detection.
The machine offers strengthened isolation able to withstanding 5 kV for 60 s (UL 62368‑1) and a primary working voltage of 1097 V. AEC‑Q100 Grade 0 qualification ensures operation over a -40 °C to +150 °C vary. Its SOICW‑16 bundle presents 1.2 mΩ conductor resistance and eight mm creepage and clearance.
Samples and analysis boards can be found to help growth.
