LTC4151IS-2#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 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 LTC4151 can also perform on-demand measurement in a snapshot mode. The LTC4151 features a dedicated shutdown pin to reduce power consumption. The LTC4151-2 feature split I2C data pins to drive opto-isolators. Typical applications include –48V telecom infrastructure, automotive, industrial and consumer.

• 12bit resolution for both current and voltages

• Additional ADC input monitors an external voltage
• Continuous scan and snapshot modes
• Shutdown mode (LTC4151) reduces quiescent current to 120µA
• 16-lead plastic SOIC package
• Temperature range from -40°C to 85°C
