Procurement Notes

Verify the exact suffix against official Torex documentation to confirm pinout and electrical characteristics match design requirements. Confirm RoHS compliance status through current manufacturer declarations. Ensure the SSOT-24 package dimensions align with PCB footprint specifications. Cross-reference datasheet revisions to validate operating temperature ranges and reset timing parameters for the specific production batch.

Selection Notes

Select this component when monitoring rechargeable battery voltages near 1.8 V is required. The manual reset feature allows direct control over system state transitions. The open-drain output simplifies interfacing with various logic families. Consider the 224 us reset delay for timing-sensitive applications. Verify compatibility with the target operating temperature range of -40 C to +105 C before finalizing the design.

Part Context

This part belongs to the XC6140 series of voltage monitors from Torex Semiconductor. These devices are categorized under PMIC supervisory circuits.
