LTC4151CMS#PBF

LTC4151 is a high side power monitor that operates over a wide voltage range of 7V to 80V. In default operation mode, the onboard 12bit ADC continuously measures high side current, input voltage and an external voltage. Data is reported through the I²C interface when polled by a host. It can also perform on-demand measurement in a snapshot mode. It features a dedicated shutdown pin to reduce power consumption. This device feature split I²C data pins to drive opto-isolators. It is widely used in application such as 48V telecom infrastructure, automotive, industrial, consumer etc.
