LTC2990 Description

Short technical summary and product information.

The LTC2990 is a versatile Quad I2C Voltage, Current and Temperature Monitor from Analog Devices / Maxim Integrated. This component is designed to measure multiple parameters, including four voltages, or combined differential voltages for current or temperature sensing with an external diode.

Key electrical specifications include a Vcc input voltage range from 2.5V to 5V. The device can monitor internal chip temperature and external temperatures via TR1 and TR2 sensors. Current measurements across V1-V2 and V3-V4 are reported, assuming a 1mOhm sense resistor, with the raw value representing voltage drop in microvolts.

This monitor IC is suitable for applications requiring detailed system monitoring. Its I2C interface simplifies integration into various embedded systems. The ability to measure voltage, current, and temperature makes it a comprehensive solution for power management and system health monitoring.

While specific package and mounting details are not provided in the available data, the LTC2990's functionality as a multifunction monitor makes it a valuable component for complex electronic designs.
