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 an
NCP45495 Features
