MCx2101 automotive current sensor ICs

Overview

The MCx2101 family are AEC-Q100 qualified, isolated AMR current sensor ICs for automotive power conversion and management, including designs with fast switching SiC and GaN power devices. They offer 5 MHz 3dB bandwidth with low phase delay, 80 ns output response and 4.8 kV isolation in a SOIC-16 package. Parts come in fixed gain (MCA) and ratiometric (MCR) versions for 3.3 V or 5 V supplies.

Built for

  • On-board chargers and fast DC chargers
  • Automotive motor drives and inverters
  • Automotive DC-DC and AC-DC supplies
  • Solar inverters and data center power
