LTC4151IDD Description

The LTC4151IDD 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 LTC4151 can also perform on-demand measurement in a snapshot mode. The LTC4151 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.
