Overview
The XC6140C21A9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging. It features a CMOS output, manual reset capability, and a backup battery switch function. The device operates within a supply voltage range up to 6 V and has a detection threshold of 2.1 V. It includes a reset delay time of 224 us and supports surface mount installation in an SSOT-24 package. The component monitors one input and lacks a watchdog timer.
Feature Summary
- Optimized for constant voltage rechargeable battery applications
- Includes manual reset and backup battery switch functions
- CMOS output interface for digital logic compatibility
Applications
- Voltage monitoring for rechargeable batteries
- Constant voltage charging system supervision
- Backup power switching circuits
Procurement Notes
Verify the specific suffix A9R against the official Torex Semiconductor datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SSOT-24 package dimensions are compatible with your PCB footprint. Confirm RoHS compliance status through the manufacturer's environmental documentation before finalizing procurement.
Selection Notes
Select this component when a fixed 2.1 V threshold is required for single-input battery monitoring. The manual reset feature necessitates external control logic or user interaction for recovery. Verify that the 224 us reset delay aligns with system startup timing constraints. Consider the SSOT-24 package size relative to available board space.
Part Context
