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 on-board 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.
