Linear Technology: High-Side Power Monitor Measures Both Current & Voltage up to 80V (LTC4151)
Accurately monitoring power consumption in a high voltage system can impact cost of operation and minimize resource waste. System power monitoring can be used to impose limits on usage. Also, if total heat output and the required airflow are known, fans can be sized more precisely for optimal air flow. By capping power to a particular system excess capacity can be freed up within a total power budget. Prior to release of Linear’s LTC4151 High Voltage I2C Current and Voltage Monitor, there was no single IC solution that enabled collection of system voltage and current data with 12-bit accuracy. The LTC4151 — a high voltage digital voltmeter (DVM) in a tiny DFN package — can be used with third-party power monitoring software to accurately monitor the actual power draw in telecommunications and blade server equipment, as well as in 12V and 24V industrial applications.
