ACS37800
Isolated, Digital Output, Power Monitoring IC
with Zero-Crossing Detection, Overcurrent and Overvoltage Flagging
DESCRIPTION FEATURES AND BENEFITS • Accurate power monitoring for AC and DC applications
• UL 60950-1 (ed. 2) and UL 62368-1 (ed. 1) certified for
reinforced isolation up to 517 VRMS in a single package
• Accurate measurements of active, reactive, and apparent
power, as well as power factor
• Separate RMS and instantaneous measurements for both
voltage and current channels
• Two programmable averaging blocks
• 0.85 mΩ primary conductor resistance for low power loss
and high inrush current withstand capability
