LTC2938HDE#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2938HDE#TRPBF is a configurable processor supervisor designed for systems requiring watchdog supervision. It monitors up to four supply voltages and features an integrated watchdog timer with programmable timeout intervals. The device operates within a supply voltage range of 1V to 7V and provides push-pull reset outputs. Packaged in a 12-pin DFN EP, it supports automotive applications and includes features such as manual reset input capability and battery backup switching.

Power Supply Controllers, Monitors Feature Summary

• Configurable multi-supply monitoring for up to four voltage rails
• Integrated watchdog timer with programmable timeout functionality
• Automotive-grade qualification for reliable operation in harsh environments

Power Supply Controllers, Monitors Applications

• Processor supervision in industrial control systems
• Watchdog monitoring in automotive electronic modules
• Multi-rail power management in embedded computing platforms

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm automotive grade compliance if required by your design specifications. Check current availability status as distribution may be limited. Ensure the DFN-12 package footprint matches your PCB layout requirements before finalizing procurement decisions.

Power Supply Controllers, Monitors Selection Notes

Select this component when multiple supply rails require simultaneous monitoring with centralized reset generation. The integrated watchdog eliminates external timing components. Consider the 12-pin DFN EP package for space-constrained designs. Verify that the 1V minimum operating voltage aligns with your system's lowest supply rail during brownout conditions.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2938 family of configurable power supervisors from Analog Devices. It complements other PMIC solutions by providing dedicated fault detection and system reset management. The HDE variant specifically denotes the automotive-qualified version housed in a compact leadless package suitable for high-density circuit board implementations.

Power Supply Controllers, Monitors Replacement Considerations

LTC2938CMS#PBF offers similar functionality in MSOP-12 packaging without automotive qualification.
