onsemi NCP45492
The NCP45492 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.| Part No. | NCP45492 |
