DESCRIPTION
The LTC®4151 and LTC4151-1 are high side power monitors that operate over a wide voltage range of 7V to 80V. In default operation mode, the onboard 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 monitors can also perform on-demand measurement in a snapshot mode. The LTC4151 features a dedicated shutdown pin to reduce power consumption. The LTC4151-1 features split I2C data pins with data in and an inverted data output to drive optoisolators.
