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.
