NCP45495

26V, 4-Channel Voltage Bus and 4-Channel High-Side Current Shunt Monitor NCP45495 The NCP45495 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 NCP45495 offers programmable voltage and current gain settings and requires a minimal amount of external passives for a small cost saving solution. The device is also configurable to operate either standalone or as a pair, permitting up to eight separate HV power supplies to be monitored and measured.
