Melexis MLX91229 Conventional Hall Current Sensors
Melexis MLX91229 Conventional Hall Current Sensors feature an advanced second-order sigma-delta digital output to deliver high signal integrity in noisy traction inverter environments. This Melexis high-performance conventional Hall (C-core) current sensor IC shifts signal transmission from the analog to the digital domain, providing an inherent noise margin that tolerates heavy electromagnetic interference (EMI). The MLX91229 supports current sensing from 200A to 2000A and is ideal for traction inverters and other automotive systems where local power electronics often disrupt standard sensor transmissions.
