S-19103C48H-M5T1U

Supervisors Overview

The S-19103C48H-M5T1U is a supervisory circuit manufactured by ABLIC Inc., belonging to the S-19103/19109 series. It functions as a voltage detector with a fixed threshold voltage of 4.8V. The device features an open-drain or open-collector output type and provides a standard reset timeout of 40µs. Designed for surface-mount installation, it utilizes an SOT-23-5 package (SC-74A). The component operates within a temperature range of -40°C to 105°C and holds AEC-Q100 automotive qualification.

Supervisors Feature Summary

• Automotive-grade voltage detection with AEC-Q100 qualification
• Open-drain/open-collector output configuration
• Ultra-compact SOT-23-5 surface-mount packaging

Supervisors Applications

• Automotive electronic system monitoring
• Voltage supervision in embedded control units
• Power management circuits requiring low-voltage detection

Supervisors Procurement Notes

Verify current availability and lead times directly with authorized distributors, as this item may be subject to factory special order status. Confirm that the SOT-23-5 package and 4.8V threshold align with specific design requirements. Ensure compliance with RoHS directives and check for any regional shipping restrictions before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a precise 4.8V detection threshold is required for automotive applications. The open-drain output necessitates an external pull-up resistor for proper logic level interfacing. Consider the 40µs reset delay for timing-sensitive designs. Verify that the operating temperature range meets environmental conditions and that the SOT-23-5 footprint fits the PCB layout constraints.
