LTC1326CS8-2.5#TRPBF

Supervisors Overview

The LTC1326CS8-2.5#TRPBF is a microprocessor supervisory circuit manufactured by Analog Devices Inc., housed in an 8-pin SOIC package. It features three independent voltage monitor channels with fixed thresholds of 2.5V, 3.3V, and 5V, alongside one adjustable channel. The device operates within a supply voltage range of 1V to 7V and draws a typical quiescent current of 40µA. It provides a reset delay time of 200ms and offers active high, active low, or open-drain output configurations. The component supports power-fail detection and includes a chip enable signal for system control.

Supervisors Feature Summary

• Provides multi-channel voltage monitoring with fixed and adjustable thresholds
• Offers flexible output logic states including active high, active low, and open drain
• Integrates power-fail detection capabilities for system reliability
• Features low quiescent current consumption for energy-efficient operation

Supervisors Applications

• Portable battery-powered equipment requiring precise voltage supervision
• Industrial control systems needing multi-rail power monitoring
• Embedded systems utilizing multiple voltage domains for core and peripheral logic

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the -2.5 designation aligns with the required fixed threshold voltages for your design. Ensure the SOIC-8 footprint matches your PCB layout constraints. Check for RoHS compliance documentation as per project requirements. Validate that the operating temperature range meets your environmental specifications.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision from a single IC. The adjustable channel allows customization for non-standard voltage levels. Consider the 200ms reset delay for timing-sensitive applications. Evaluate the low static current against battery life requirements. Compare output drive capabilities with downstream logic inputs.

Supervisors Part Context

This part belongs to the LTC1326 series of supervisory circuits designed for monitoring multiple power supplies. It complements other Analog Devices PMIC solutions by providing dedicated voltage monitoring without complex digital interfaces. The SOIC-8 package offers a compact solution for space-constrained designs compared to larger resistor-network alternatives.
