XC6140N22C9R-G

Overview

The XC6140N22C9R-G is a voltage monitoring IC designed for rechargeable batteries with constant voltage charging. It features an open-drain output and manual reset capability. The threshold voltage is 2.2 V, with a reset delay time of 224 us. The maximum power supply voltage is 6 V. Operating temperature range is -40°C to +105°C. It includes a battery backup switch function.

Feature Summary

• Integrated battery backup switch for maintaining system state during power transitions
• Manual reset functionality allows precise control over the reset signal timing
• Open-drain output configuration provides flexibility in interfacing with various logic levels

Applications

• Voltage monitoring for single-cell rechargeable batteries
• System supervision in portable electronic devices
• Power management circuits requiring manual reset control

Procurement Notes

Verify the specific suffix C9R-G matches the required threshold and package variant. Confirm the 4-USPQ-B05 package dimensions against PCB layout requirements. Ensure the operating temperature range meets the application's environmental specifications. Check for RoHS compliance status if required by project standards.

Selection Notes

Select this component when a fixed 2.2 V threshold is appropriate for the monitored battery cell. Consider the manual reset feature if hardware-based reset control is preferred over automatic detection. Evaluate the 224 us reset delay against the system's noise immunity needs. Compare power consumption and package size against alternative supervisory ICs.

Part Context

This part belongs to the XC6140 series from Torex Semiconductor, which specializes in voltage monitoring ICs for battery applications. The series offers various threshold voltages and package options to suit different design constraints. The XC6140 series is known for its low power consumption and high accuracy, making it suitable for energy-efficient portable devices.

Replacement Considerations

XC6140C19A9R-G: Different threshold voltage (1.9 V) and package (4-XDFN). XC6126N22ANR-G: Similar threshold but different reset delay (30 us) and package (SSOT-24-4). Verify electrical parameters and physical dimensions before substitution.
