LTC1326IMS8#PBF

Supervisors Overview

The LTC1326IMS8#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor monitoring applications. It features three independent voltage monitor inputs with threshold options of 3.3 V, 5 V, or adjustable settings. The device provides active high, active low, and open drain output configurations to accommodate various system logic requirements. It operates within a supply voltage range of 1 V to 7 V and maintains an accuracy of 0.75%. The reset delay time is fixed at 200 ms, and the chip supports a chip enable signal for power management.

Supervisors Feature Summary

• Monitors up to three independent input voltages simultaneously
• Offers flexible output polarity including active high, active low, and open drain
• Includes a chip enable pin for controlled operation and power saving

Supervisors Applications

• Microprocessor power supply monitoring
• Voltage supervision in embedded systems

Supervisors Procurement Notes

Verify the specific suffix and package variant against official Analog Devices documentation to ensure compatibility with design specifications. Confirm RoHS compliance status through current manufacturer declarations. Check availability constraints as distribution channels may report limited stock or discontinuation notices. Validate that the selected part number matches the required threshold and output configuration for the target application.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision within a compact footprint. The adjustable threshold option allows customization for non-standard voltage levels. Ensure the operating temperature range of 0°C to +70°C aligns with the environmental conditions of the end product. Consider the 40 µA operating current for low-power battery-driven designs requiring efficient standby modes.
