S-19190AGH-M6T1U

Overview

The S-19190AGH-M6T1U is a battery monitor IC from ABLIC, designed for monitoring battery voltage in automotive and industrial applications. It features an active high CMOS output and includes a built-in watchdog timer for system reliability. 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, ensuring precise detection of low-voltage conditions. The component supports manual reset functionality and does not include a backup switch, making it suitable for straightforward supervisory roles where continuous monitoring and fault protection are required.

Feature Summary

• Integrates a watchdog timer to enhance system stability and prevent software lockups during abnormal operating conditions.
• Provides an active high CMOS output signal for clear status indication when the monitored voltage exceeds the set threshold.
• Supports manual reset capability, allowing external control over the reset state for flexible system integration.

Applications

• Automotive battery voltage supervision
• Industrial equipment power monitoring
• Battery management systems requiring watchdog protection

Procurement Notes

Verify the exact part number suffix against the manufacturer's latest datasheet to ensure compatibility with specific threshold voltages and package variants. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region. Ensure that the ordering quantity meets the minimum packaging requirements specified in the official documentation.

Selection Notes

Select this component when a dedicated battery monitor with integrated watchdog functionality is required. The 2.4 V threshold suits applications where early warning of battery depletion is critical. Consider the SOT-23-6 package size for space-constrained designs. Verify that the active high output logic aligns with the input requirements of the downstream microcontroller or logic circuitry.

Part Context

This part belongs to the S-19190 series of battery monitors from ABLIC, which are specifically engineered for automotive and general-purpose battery supervision. The series is known for combining voltage monitoring with watchdog timers in a compact form factor. The S-19190AGH variant represents a specific configuration within this family, tailored for applications needing manual reset and active high outputs.

Replacement Considerations

Check for direct substitutes within the S-19190 series with different threshold voltages if the 2.4 V level is unsuitable. Cross-reference pinout compatibility with other SOT-23-6 voltage detectors from ABLIC or competitors before substitution.
