R5111S072D-E2-KE

Supervisors Overview

The R5111S072D-E2-KE is a supervisory circuit voltage detector manufactured by Nisshinbo Micro Devices. It features a 36 V maximum power supply voltage and operates within a temperature range of -40°C to +125°C. The device monitors a single input with an active low, open drain output. Key electrical parameters include a threshold voltage of 3.7 V, an overvoltage threshold of 3.766 V, and an undervoltage threshold of 3.634 V. It incorporates a watchdog timer and manual reset functionality. The reset delay time is 242 ms, and the accuracy is specified at 1.8%. The operating supply current is 25 uA.

Supervisors Feature Summary

• Integrated watchdog timer for system monitoring
• Manual reset capability for controlled recovery
• Automotive qualification compliant with AEC-Q100 standards

Supervisors Applications

• Automotive system power supply monitoring
• Voltage supervision in automotive electronic control units
• Watchdog timer implementation in vehicle networks

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm pinout and functional variations. Ensure the HSOP-8E-8 package matches the target PCB footprint. Confirm AEC-Q100 certification requirements are met for the intended automotive application environment before finalizing procurement.

Supervisors Selection Notes

Select this component when a 36 V tolerant supervisor with integrated watchdog and manual reset is required. The 3.7 V threshold suits applications needing precise voltage monitoring near standard logic levels. Consider the 25 uA supply current for low-power constraints and the wide temperature range for harsh environments.
