LTC4151-1 - High Voltage I2C Current and Voltage Monitor

Download the LTC4151-1 datasheet PDF. This datasheet also covers the LTC4151 variant, as both devices belong to the same high voltage i2c current and voltage monitor family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®4151 is a high side power monitor that operates 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.
