High-Side Power Monitor Measures Both Current and Voltage up to 80V

(pressebox) 19.02.2008 - 12:46 Uhr - 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,...
