LTC2992CMS#PBF

Power Supply Controllers, Monitors Overview

The LTC2992CMS#PBF is a rail-to-rail system monitor manufactured by Analog Devices Inc. in a 16-pin MSOP package. It measures current, voltage, and power for two independent power supplies with a wide input range of 0V to 100V, independent of the supply voltage. The device operates on a supply voltage between 2.7V and 100V and includes an internal shunt regulator for monitoring voltages exceeding 100V. It features a selectable I2C interface operating at standard or fast modes up to 400kHz.

Power Supply Controllers, Monitors Feature Summary

• Simultaneous measurement of current, voltage, and power across two independent channels
• Rail-to-rail operation allowing 0V to 100V voltage sensing regardless of supply voltage
• Integrated shunt regulator enables accurate monitoring of voltages above 100V
• Configurable I2C communication interface supporting multiple clock speeds

Power Supply Controllers, Monitors Applications

• -48V redundant power feed systems with transient protection
• Bidirectional high-side power monitoring for 30V to 300V applications
• Dual bipolar power supply monitoring
• High-power dual 12V monitoring combined with negative voltage supervision

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix against official documentation, as the provided model lacks the '-1' designation found in common listings. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors due to potential limited availability. Ensure the selected variant matches the required I2C address configuration before procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when simultaneous multi-parameter monitoring of two rails is required within a 100V window. The integrated shunt regulator makes it suitable for high-voltage inputs exceeding the supply rail. Verify that the I2C bus speed requirements align with the device's configurable interface options and that the MSOP-16 package fits the PCB layout constraints.
