LTC2917IMS-B1#PBF

Supervisors Overview

The LTC2917IMS-B1#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring voltage levels in electronic systems. It operates within a supply voltage range of 2.7V to 36V and features an adjustable watchdog timer with selectable thresholds. The device provides open-drain reset output and includes a manual reset input. It is housed in a 10-lead MSOP package and functions reliably across an industrial temperature range from -40°C to +85°C, ensuring robust performance in demanding environments.

Supervisors Feature Summary

• Supports 27 selectable threshold voltages for precise under-voltage and over-voltage detection
• Features an adjustable watchdog timer with timeout period selection
• Includes a manual reset input pin for system control flexibility
• Provides open-drain reset output compatible with various logic families

Supervisors Applications

• Portable equipment power management
• Industrial control systems
• Telecommunications infrastructure
• Automotive electronics monitoring

Supervisors Procurement Notes

Verify the specific suffix B1 indicates the correct threshold configuration before procurement. Confirm RoHS compliance status through official documentation. Check availability as distribution may be limited or subject to factory order constraints. Ensure the MSOP-10 package matches your PCB footprint requirements. Validate operating temperature range suitability for your specific application environment.

Supervisors Selection Notes

Select this component when multiple voltage thresholds are required without external resistors. Consider the adjustable watchdog timer for system reliability enhancement. Evaluate the low quiescent current for battery-powered applications. Compare against single-threshold monitors if fewer inputs are sufficient. Verify compatibility with system logic levels due to the open-drain output structure.

Supervisors Part Context

This part belongs to the LTC2917 series of voltage supervisors from Analog Devices. The series offers configurable monitoring solutions with integrated watchdog functionality. The IMS variant denotes the MSOP package option. The #PBF suffix indicates lead-free packaging compliant with environmental standards. This family targets applications requiring flexible voltage supervision in compact form factors.

Supervisors Replacement Considerations

LTC2917IMS-A1#PBF offers similar functionality with different default threshold configurations. LTC2918IMS-B1#PBF provides comparable features with slight parameter variations. Verify electrical characteristics and pinout compatibility before substitution. Ensure the replacement supports the required watchdog timeout ranges. Confirm package dimensions match existing board layouts.
