The LTC2991CMS#PBF is an Octal I2C Temperature, Voltage and Current Monitor with Current and Power Monitors and Regulators from Analog Devices. This part features an I2C-compatible interface that facilitates communication over two lines to 10 separate internal monitoring devices. The IC is capable of monitoring up to 8 external and 2 internal thermistors, 8 independent external voltage inputs, 8 high-side current shunt inputs, 5 current-sense amplifiers, 8 general-purpose digital I/O pins, and temperature of the designed system. It offers high accuracy current, voltage, and temperature measurements with 16-bit resolution and includes programmable over-temperature and over-current protection. There is also built-in reset monitoring with adjustable delay. This part is housed in a small 8-lead Plastic lead (PBF) package. The device offers a wide range of features for efficient system monitoring, with a wide operating temperature range of -40°C to +125°C.
