The LTC2991IMS#TRPBF by Analog Devices is an octal I2C voltage, current, and temperature monitor designed for comprehensive system monitoring. It can individually measure supply voltages and pair inputs for differential measurements across current sense resistors or temperature sensing transistors. The device includes internal temperature and VCC measurements, offering flexibility with selectable addresses and configurable functionality.
Key electrical specifications include a supply voltage range of 2.9V to 5.5V and a 14-bit ADC for voltage and current measurements. Temperature monitoring offers typical accuracy of 0.7°C for remote diodes and 1°C for the internal sensor, with a resolution of 0.06°C. The device operates within a temperature range of -40°C to 85°C.
Packaged in a 16-MSOP or 16-TFSOP, the LTC2991IMS#TRPBF is suitable for surface mount applications. It provides output alarm and fan control signals, making it ideal for environmental monitoring, supply voltage monitoring, and remote data acquisition systems. The internal 10ppm/°C voltage reference minimizes supporting components and board space.
This monitor IC is designed for systems requiring sub-millivolt voltage resolution, 1% current measurement, and 1°C temperature accuracy. Its ESD rating is up to 6kV HBM for the inputs, ensuring robustness in various operating conditions.
