XC6140N16A9R-G

Overview

The XC6140N16A9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features a threshold voltage of 1.6 V and operates within a maximum supply voltage of 6 V. The device provides an open-drain output type and includes manual reset functionality without a watchdog timer. It incorporates a battery backup switch and has a reset delay time of 224 us. The component supports one monitored input and is housed in an SSOT-24 package, suitable for surface mount installation across a temperature range of -40 C to +105 C.

Feature Summary

• Integrated constant voltage charging control for rechargeable batteries
• Manual reset capability with defined reset delay timing
• Battery backup switch support for power continuity management

Applications

• Rechargeable battery voltage monitoring systems
• Constant voltage charging circuit supervision
• Portable electronic device power management

Procurement Notes

Verify the specific suffix A9R against official Torex documentation to confirm pinout and electrical characteristics match design requirements. Ensure the SSOT-24 package dimensions align with PCB layout constraints. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a dedicated voltage monitor with integrated CV charging control is required for single-input battery applications. The open-drain output suits logic interfaces requiring external pull-up resistors. Consider the 1.6 V threshold specifically for low-voltage battery protection scenarios where precise under-voltage detection is critical.

Part Context

This part belongs to the XC6140 series from Torex Semiconductor, specialized for supervisory circuits in power management applications. The series focuses on rechargeable battery protection with integrated charging controls. The N-series designation typically indicates specific output configurations within the broader product family.

Replacement Considerations

Cross-reference XC6140C16A9R-G for CMOS output alternative. Verify XC6140N17A9R-G if a 1.7 V threshold is acceptable. Check XC6140N18A9R-G for higher threshold options. All substitutes must maintain SSOT-24 packaging compatibility.
