Overview
The XC6140N17A9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging capabilities. It features a threshold voltage of 1.7 V and operates within a maximum supply voltage of 6 V. The device utilizes an SSOT-24 package and supports surface mount installation. It includes manual reset functionality, a backup battery switch, and provides an open-drain output type. The reset delay time is specified at 224 us, and it monitors a single input without a watchdog timer.
Feature Summary
- Integrated constant voltage charging function optimized for rechargeable battery applications
- Manual reset capability allows user-controlled system recovery
- Backup battery switch ensures continuous monitoring during power transitions
Applications
- Rechargeable battery voltage monitoring systems
- Constant voltage charging circuit supervision
- Portable electronic device power management
Procurement Notes
Verify the specific suffix 'N17' confirms the 1.7 V threshold voltage and 'A9R' indicates the SSOT-24 package configuration. Confirm RoHS compliance status through official datasheets. Check regional availability as distribution may be restricted in certain areas. Ensure compatibility with the target PCB footprint before ordering.
Selection Notes
Select this component when a precise 1.7 V detection level is required for battery protection. The open-drain output suits interfaces requiring external pull-up resistors. Consider the SSOT-24 package size constraints against available board space. Verify that manual reset meets the system's fault recovery requirements rather than automatic restart.
Part Context
Part of the XC6140 series from Torex Semiconductor, specialized for battery monitoring. This series leverages CMOS technology for high accuracy. The XC6140N17A9R-G specifically targets applications needing low-voltage detection with integrated charging supervision features.
Replacement Considerations
Check XC6140C17A9R-G for CMOS output alternative. Verify XC6140N18A9R-G if a slightly higher threshold is acceptable. Consult official substitution lists for pin-compatible upgrades.
