Overview
The XC6140C18A9R-G is a voltage monitoring IC designed for rechargeable batteries, featuring constant voltage charging control. It operates within a supply voltage range up to 6 V and includes a manual reset function with a fixed reset delay time of 224 us. The device utilizes an SSOT-24 package and provides a CMOS output type. It supports battery backup switching and monitors a single input channel. The threshold voltage is set at 1.8 V, allowing precise detection of low-voltage conditions in portable electronic applications.
Feature Summary
- Integrates constant voltage charging control functionality specifically tailored for rechargeable battery management systems.
- Provides manual reset capability with a defined reset delay time to ensure stable system recovery after undervoltage events.
- Supports battery backup switching to maintain critical data or state during power transitions.
Applications
- Rechargeable battery voltage monitoring
- Constant voltage charging circuit supervision
- Portable electronic device power management
Procurement Notes
Verify the exact threshold voltage and package variant against the manufacturer's official datasheet before procurement. Confirm RoHS compliance status and specific ordering suffixes required for your region. Ensure the SSOT-24 footprint matches your PCB design constraints. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a dedicated voltage monitor with integrated CV charging control is required for single-cell rechargeable batteries. The CMOS output interface is suitable for direct connection to digital logic inputs. Consider the manual reset feature if external reset generation is preferred over automatic triggering. Verify that the 1.8 V threshold aligns with the minimum operating voltage of the monitored system.
