26V, 4-Channel Voltage Bus and 4-Channel High-Side Current Shunt Monitor 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.

NCP45492 Features

* Translates and Scales Shunt and Bus Voltages up to 26 V

* Single Device Monitors Four Supplies

* May Be Paired for Monitoring Up To Eight Supplies

* Very Low Powerdown Current

* All Channels Individually Gain Programmable by External Resistor Selection
