XC6140C19C9R-G

Overview

The XC6140C19C9R-G is a voltage monitoring IC designed for rechargeable batteries, featuring constant voltage charging control. It operates within a maximum supply voltage of 6 V and detects input voltages with a threshold of 1.9 V. The device provides a CMOS output and includes manual reset functionality with a reset delay time of 224 us. It supports battery backup switching and is housed in an SSOT-24 package. The component functions reliably across an operating temperature range from -40 C to +105 C.

Feature Summary

• Integrates constant voltage charging control specifically for rechargeable battery applications
• Provides manual reset capability with defined delay timing for system stability
• Supports battery backup switching to maintain power continuity during transitions

Applications

• Voltage monitoring for rechargeable battery systems
• Constant voltage charging circuit supervision
• Battery backup switching management

Procurement Notes

Verify the specific suffix codes against official Torex documentation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status through current manufacturer declarations. Check regional availability as distribution may be restricted in certain areas. Validate that the SSOT-24 package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a dedicated voltage monitor with integrated CV charging control is required for single-input battery applications. Ensure the 1.9 V threshold aligns with your battery cell specifications. Verify that the SSOT-24 package fits your design constraints. Consider the manual reset feature if external watchdog timers are not utilized in the system architecture.

Part Context

This part belongs to the XC6140 series of supervisory circuits manufactured by Torex Semiconductor. The series focuses on power management ICs for battery-powered devices. The XC6140C19C9R-G specifically addresses the need for combined voltage monitoring and charging control in a compact surface-mount package suitable for portable electronics.

Replacement Considerations

Consult official Torex cross-reference documents for verified substitutes. Generic equivalents may lack the integrated CV charging control feature. Ensure any replacement maintains the 1.9 V threshold and SSOT-24 package compatibility.
