NCP45491中文资料4-Channel Voltage Bus and 4-Channel High-Side Current Shunt Monitor, 26 V数据手册ONSEMI规格书

描述 Description

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 either standalone or as a pair, permitting up to eight separate HV power supplies to be monitored and measured.

特性 Features

• Translates and scales voltage and currents on buses up to 26V
• Single device monitors up to 4 supplies
• Ultra-low offset shunt amplifier (
• May Be Paired for Monitoring Up To Eight Supplies
• Very low power down current
• All Channels Individually Gain Programmable by External Resistor Selection
• Fast Settling Time
• Real-Time Indication of All Bus Voltages Valid
• Adjustable Output Common-Mode Voltage Adapts to Most External ADCs
• Lead-Free Device

应用 Application

• Power Monitoring and Management
• Power Control Loops
• Graphical Cards
• Desktop Computers
• Notebooks
• Set-top boxes
• Enterprise Servers
• Telecom Equipment
