MILPITAS, CA February 18, 2008 Linear Technology Corporation introduces the LTC4151, a high side power monitor that measures current and input voltages from 7V to 80V. The LTC4151 utilizes an internal 12-bit ADC to continuously measure both high side current and input voltage to give a true power reading. The LTC4151 replaces prior solutions that use costly current sense amplifiers with a separate ADC, a hot-swap controller with an ADC, or an ADC with a floating ground. These older implementations are in many cases limited by the ADC's input voltage range (typically 5V or 10V), are much more expensive, require more board space, and are not reliable. The LTC4151's simple, single-chip solution is ideal for 48V telecom equipment, advanced mezzanine cards (AMC), and blade servers used for measuring input power over a wide input range. |
