S-19190ACH-M6T1U

Overview

The S-19190ACH-M6T1U is a voltage monitor supervisory circuit manufactured by ABLIC Inc. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 2.8 V. The device utilizes an SOT-23-6 surface-mount package and provides an active high, CMOS output type. It includes an integrated watchdog timer function but lacks manual reset capability and battery backup switching. The component supports operation across a wide temperature range from -40°C to +105°C.

Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides active high CMOS output signal
• Operates with low supply voltage down to 1.2 V

Applications

• Embedded system power supervision
• Microcontroller reset circuitry
• Battery-powered device monitoring

Procurement Notes

Verify the specific suffix 'M6T1U' against official ABLIC documentation to confirm reel packaging and tape specifications. Ensure the threshold voltage matches the required 2.8 V application need. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference the part number with authorized distributor lists to avoid counterfeit components. Validate thermal performance requirements against the specified operating temperature range.

Selection Notes

Select this component when a fixed 2.8 V threshold is required for voltage monitoring applications. The active high output configuration suits systems expecting a logic high state during normal operation. The inclusion of a watchdog timer makes it suitable for environments requiring fault detection. Consider the SOT-23-6 package size for space-constrained PCB layouts. Verify that the 1.2 V minimum operating voltage aligns with the system's lowest expected supply level.
