Power Monitor Measures Current and Voltage
Linear Technology Corp. introduced its LTC4151 high side power monitor that measures current and input voltages from 7V to 80V. The monitor uses an internal 12-bit ADC to continuously measure both high side current and input voltage to give a true power reading. It replaces prior units that use costly current sense amplifiers with a separate ADC, a hot-swap controller with an ADC, or an ADC with a floating ground. The monitor’s simple, single-chip system is suitable for 48V telecom equipment, advanced mezzanine cards (AMC) and blade servers that are used for measuring input power over a wide input range. It is also appropriate for power monitoring in industrial applications running at 12V or 24V.
