Current shunt monitor

29 May 2019 Power Electronics / Power Management

ON Semiconductor’s NCP45491 is a high-performance monolithic IC which can be used to monitor bus voltage and current on four high-voltage power supplies simultaneously.

The HV bus voltages and currents are translated to a low-voltage power domain and multiplexed onto a single differential output for measurement externally by common ADCs (analog-to-digital converters). The device monitors current and voltage up to 26 V, includes an indicator that all busses are valid, and has an adjustable output common-mode.

The device is configurable to operate either standalone or as a pair, permitting up to eight separate HV power supplies to be monitored and measured.
