DESCRIPTION

High Voltage I2C Current

and Voltage Monitor

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.
