Onsemi NCP45491

Beschreibung

The 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. 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.
