LTC2992CDE-1#PBF

Power Supply Controllers, Monitors Overview

The LTC2992CDE-1#PBF is a rail-to-rail system monitor manufactured by Analog Devices Inc., designed to measure current, voltage, and power for two independent power supplies. It operates within a supply voltage range of 2.7 V to 100 V and features an integrated shunt regulator for monitoring supplies exceeding 100 V. The device supports high-side or low-side sensing configurations with an input voltage range of 0 V to 100 V. It utilizes a 16-pin DFN EP package suitable for surface mount installation. The component functions with a maximum operating temperature of +70 C and draws a typical operating supply current of 1.2 mA.

Power Supply Controllers, Monitors Feature Summary

• Measures current, voltage, and power for two separate power supplies simultaneously
• Includes an integrated shunt regulator for monitoring power supplies above 100 V
• Supports both high-side and low-side current sensing configurations

Power Supply Controllers, Monitors Applications

• -48V redundant feed systems with transient protection up to 200V
• Four-quadrant power monitoring applications
• Dual bipolar power supply monitoring
• High-side power monitoring for dual 12V and negative voltage rails

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #PBF indicates lead-free tin plating compatible with RoHS standards. Confirm the DFN-16 package type matches the target PCB footprint requirements. Ensure the I2C interface speed aligns with the system controller capabilities, as this variant specifies a 1.5kHz interface limit in typical application contexts. Check automotive qualification status if required for the specific end-use environment.

Power Supply Controllers, Monitors Selection Notes

Select this component when simultaneous dual-supply monitoring is required with a wide input voltage range up to 100 V. The integrated shunt regulator allows for monitoring voltages beyond the standard supply range without external level shifting. Consider the 1.2 mA supply current for low-power system designs. The DFN-16 package offers a compact solution for space-constrained industrial or automotive boards requiring precise power management data acquisition.
