ADI LTC4151HMS#PBF

电源监控器7V ~ 80V7V ~ 80V1.2 mA

Overview

The LTC4151HMS#PBF is a high side power monitor that operates over a wide voltage range of 7V to 80V. In default operation mode, the on-board 12-bit ADC continuously measures high side current, input voltage and an external voltage. Data is reported through the I2C interface when polled by a host. The LTC4151HMS#PBF can also perform on-demand measurement in a snapshot mode. The LTC4151HMS#PBF features a dedicated shutdown pin to reduce power consumption. The LTC4151‑1/LTC4151-2 feature split I2C data pins to drive opto-isolators. The data out on the LTC4151-1 is inverted while that on the LTC4151-2 is not.
