R0050 Power Sensor CAN L4
Our new power sensor features the ACS37220 sensor, a fast and efficient high-current sense element covering a 5–36 V DC operating range and supporting continuous current sensing up to 100 A.
The ACS37220 is a Hall-effect based magnetic current sensor with a galvanically isolated current path. The device measures current through an internal conductor with an ultra-low resistance of 100 µΩ, minimizing power dissipation at high currents.
Differential Hall sensing provides strong rejection of common-mode magnetic fields, improving measurement accuracy in electrically noisy environments.
Power supply and communications are exposed through a JST-GH connector, providing CAN, VCC PDB, and GND.
This part includes a 6-pin JST-GH to 4+6 wire.
