The project described here is a 3-Phase isolated Hall-effect current sense amplifier with +/-600-V working voltage range. The current sensor senses magnetic flux generated from current passing through the lead frame at common-mode voltages 0 to 600V DC and provides proportional output voltage. The circuit is based on TMCS1101 IC which is a galvanically isolated Hall-effect current sensor capable of DC or AC current measurement with high accuracy, excellent linearity, temperature stability and has a bandwidth of 80KHz. A low-drift, temperature-compensated signal chain provides < 1.5% full-scale error across the device temperature range. The input current flows through an internal 1.8-mΩ conductor that generates a magnetic field measured by an integrated Hall-effect sensor. This structure eliminates external concentrators and simplifies design.
