S-19190ARH-M6T1U

Overview

The S-19190ARH-M6T1U is a voltage monitor from the ABLIC S-19190 series, designed for battery backup switching applications. It features an active high CMOS output and integrates a watchdog timer. The device operates within a temperature range of -40°C to +105°C and utilizes an SOT-23-6 surface-mount package. Key electrical parameters include a threshold voltage of 2.4 V and compliance with RoHS standards.

Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides active high CMOS output signal
• Supports battery backup switching functionality

Applications

• Battery backup power management systems
• Embedded system voltage supervision
• Industrial control circuit protection

Procurement Notes

Verify the specific suffix M6T1U against official datasheets to confirm package type and tape/reel specifications. Confirm RoHS compliance status and operating temperature range requirements match application needs. Check for automotive qualification if used in vehicle electronics. Ensure manual reset and backup switch configurations align with design constraints.

Selection Notes

Select this component when a watchdog timer and battery backup switching are required in a compact SOT-23-6 package. Compare threshold voltage accuracy and reset delay times against other S-19190 variants. Consider the active high output polarity relative to downstream logic interfaces. Evaluate thermal performance within the specified -40°C to +105°C operational window.

Part Context

Part of the S-19190 series focusing on battery management and supervision. This series distinguishes itself by combining voltage monitoring with watchdog capabilities and backup switching functions, targeting applications requiring robust power integrity and automated failover mechanisms without external discrete components.

Replacement Considerations

Consult official substitution lists for parameter-equivalent parts within the S-19190 family. Verify pin compatibility and electrical characteristics before replacing. Generic equivalents may lack integrated watchdog or backup switching features.
