LTC4151CDD#TRPBF

Power Supply Controllers, Monitors Overview

The LTC4151CDD#TRPBF is a high-side power monitor manufactured by Analog Devices Inc., designed for precise current and voltage measurement in systems operating between 7V and 80V. It integrates a 12-bit analog-to-digital converter (ADC) to provide digital output via an I²C interface, eliminating the need for external calibration in many applications. The device operates with a supply voltage range of 7V to 80V and draws a typical quiescent current of 1.2 mA. Housed in a compact DFN-10 package, it supports surface-mount installation and functions within a temperature range of 0°C to +70°C.
