NCP45491 Datasheet 4-channel Voltage Bus And 4-channel High-side Current Shunt Monitor

Manufacturer: onsemi

Overview: DATA SHEET .onsemi. 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 mon 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.
