NCP45492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 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, permitting up to eight separate HV power supplies to be monitored and measured.

特性 Features

• Translates and scales voltage and currents o 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 ADC's
• Lead-Free Device
