S-19103N34H-M5T1U

Supervisors Overview

The S-19103N34H-M5T1U is a supervisory circuit manufactured by ABLIC Inc., belonging to the S-19103 series. It functions as a voltage detector with a threshold voltage of 3.4V. The device features an open-drain or open-collector output type and provides a low-active reset signal. It includes a standard reset timeout of 40µs. The component operates within a temperature range of -40°C to +105°C and is qualified under AEC-Q100 automotive standards. It is housed in an SC-74A (SOT-753) package.

Supervisors Feature Summary

• Automotive-grade voltage detection with AEC-Q100 qualification
• Open-drain or open-collector output configuration for flexible interfacing
• Standard 40µs reset timeout ensures reliable system recovery

Supervisors Applications

• Automotive electronic system monitoring
• Voltage supervision in microcontroller units
• Power management circuits requiring undervoltage detection

Supervisors Procurement Notes

Verify current availability and lead times directly with authorized distributors, as this item may be subject to factory special order requirements. Confirm that the specific threshold voltage of 3.4V aligns with your design specifications. Ensure compatibility with the SOT-753 package footprint and check for any regional distribution restrictions before placing orders.

Supervisors Selection Notes

Select this component when an automotive-qualified voltage detector with open-drain output is required. The 3.4V threshold suits applications needing precise undervoltage monitoring at this specific level. Consider the 40µs reset delay for timing constraints. Verify that the operating temperature range meets environmental demands.
