400kHz High-Accuracy Current Sensor with Pin-Selectable Gains

ACS37002

Markets Served

The ACS37002 family of Hall-effect current sensor ICs delivers 400 kHz bandwidth, pin-selectable gains, and fast, adjustable overcurrent fault protection. The MC package (0.27 mΩ) comes as LMCA, with reinforced isolation to 572 V_RMS (CTI Group II) at 150°C, or KMCD, industrial only (–40°C to 125°C) with 880 V_RMS reinforced isolation (CTI Group I, >600 V). The MA package (0.85 mΩ) offers 565 V_RMS reinforced isolation; LA (1.0 mΩ) delivers lower noise performance at 500 V_RMS.
