LMP8645 and LMP8645HV precision detection of the presence of a small differential voltage in the presence of a high input supply voltage range from 2.7V to 12V common mode voltage at both ends of the resistor.
LMP8645 accepts and input common mode voltages range from -2V to 42V signals, while LMP8645HV accepts input signals common mode voltages range from -2V to 76V. In applications where LMP8645 and LMP8645HV adjustable gain, the supply current and high common-mode voltage are the decisive factors. The gain configuration is a resistor that provides a high degree of flexibility with an accuracy of 2% (maximum), including a low resistance for the gain setting. Output buffering to provide low output impedance. This high-side current-sense amplifier is ideal for detecting and monitoring errors in current, over-temperature, excellent AC and DC specifications, current-sense loops, and keeping them to a minimum in DC or battery-powered systems. LMP8645 ideal for industrial, automotive, and consumer electronics applications, it is available in a TSOT-6 package.
