LTC2956IMS-1#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2956IMS-1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels and provide system reset functionality. It operates within a supply voltage range of up to 36 V and features a threshold voltage of 900 mV. The device monitors one input and offers active high, active low, and open drain output types with a reset delay time of 250 ms. It consumes 800 nA of operating current and functions between -40°C and +85°C. Packaged in an MSOP-12 format, it lacks manual reset, watchdog timer, or battery backup switch capabilities.

Power Supply Controllers, Monitors Feature Summary

• Provides voltage monitoring with configurable active high, active low, and open drain outputs
• Features a wake-up timer controlled via pushbutton for system management
• Operates with ultra-low power consumption suitable for battery-backed applications

Power Supply Controllers, Monitors Applications

• Embedded systems requiring reliable voltage supervision
• Portable devices needing low-power monitoring solutions
• Industrial equipment utilizing pushbutton-controlled reset sequences

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from the tube-packaged #PBF variant. Confirm availability status as restricted supply may apply. Ensure the MSOP-12 package matches design requirements. Validate that the 900 mV threshold aligns with target voltage rails. Check RoHS compliance documentation for regulatory adherence.

Power Supply Controllers, Monitors Selection Notes

Select this component when a single-input voltage monitor with pushbutton control is required. The 900 mV threshold suits lower voltage rails compared to higher threshold variants. The MSOP-12 package offers compact surface-mount integration. Consider the 250 ms reset delay for timing-sensitive applications. Evaluate the 800 nA quiescent current against strict power budgets.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2956 series of supervisory circuits from Analog Devices. It shares functional similarities with other models in the family but differs in package type and specific electrical thresholds. The IMS-1 designation specifies the pinout and threshold characteristics unique to this variant within the broader product line.
