Overview
The XC6140N18C9R-G is a voltage monitoring IC from the XC6140 series by Torex Semiconductor, designed for rechargeable batteries with constant voltage charging. It features a detection threshold of 1.8 V and operates within a supply voltage range up to 6 V. The device utilizes an SSOT-24 package and provides an open-drain output type. It includes manual reset functionality and a battery backup switch, with a reset delay time of 224 us. The component supports a single input for voltage monitoring and lacks a watchdog timer.
Feature Summary
- Integrated constant voltage charging control for rechargeable batteries
- Manual reset capability for system recovery
- Battery backup switch for power continuity management
Applications
- Rechargeable battery voltage monitoring
- Constant voltage charging circuit supervision
- System reset generation in portable devices
Procurement Notes
Verify the specific suffix C9R against the official datasheet to confirm package type and output configuration. Ensure compatibility with the target operating temperature range of -40°C to +105°C. Confirm RoHS compliance status through the manufacturer's environmental documentation before integration into regulated products.
Selection Notes
Select this part when a 1.8 V threshold is required for single-input voltage monitoring. The open-drain output suits interfaces requiring external pull-up resistors. Consider the SSOT-24 package for space-constrained surface-mount designs. Verify that manual reset meets system timing requirements instead of automatic reset variants.
Part Context
This component belongs to the XC6140 series of supervisory circuits optimized for battery-powered applications. It integrates voltage detection with charging management features, distinguishing it from standard voltage detectors. The series offers various threshold voltages and package options to accommodate different rechargeable battery chemistries and system architectures.
