5962-8774001FA

Overview

The Texas Instruments 5962-877401FA is a power supply supervisory circuit housed in a 16-pin ceramic flat package (CFP). It operates as a voltage supervisor with open drain or open collector output, supporting a single channel. The device features an internal accurate reference and programmable time delays for under-voltage and over-voltage detection. It includes SCR crowbar drive capability with 300 mA output current. The component is designed for military-grade applications within a temperature range of -55°C to 125°C.

Feature Summary

• Integrates over-voltage, under-voltage, and current sensing circuits
• Features an internal 1% accurate reference voltage source
• Supports programmable time delays for precise supervision timing
• Includes SCR crowbar drive functionality with high current capacity

Applications

• Military grade power supply monitoring systems
• Voltage supervisor circuits requiring precise reference accuracy
• SCR crowbar protection implementations
• Systems needing programmable delay for fault response

Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or factory special order conditions. Confirm the exact package type and temperature rating match your design requirements before procurement. Ensure compatibility with existing board layouts due to the specific 16-CFP footprint. Check for any obsolescence notices or lifecycle changes that might affect long-term production support.

Selection Notes

Select this component when a robust, military-grade supervisory circuit with integrated SCR drive is required. The internal 1% reference eliminates the need for external precision components. Consider the programmable delay feature if specific timing thresholds are necessary for system stability. Verify that the 16-CFP package fits within the thermal and spatial constraints of the target application.

Part Context

This part belongs to the family of power supply supervisory circuits from Texas Instruments. It is specifically designed for high-reliability environments where precise voltage monitoring and immediate fault response are critical. The inclusion of SCR crowbar drive distinguishes it from standard reset controllers, offering enhanced protection capabilities for sensitive loads.
