DATA SHEET www.onsemi.com 26V, 4-Channel Voltage Bus and 4-Channel High-Side Current Shunt Monitor NCP45491 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 eit.

NCP45491 Features
