XC6190BN258R-G

Supervisors Overview

The XC6190BN258R-G is a voltage supervisory circuit manufactured by Torex Semiconductor Ltd, designed for monitoring power supply integrity. It features a USPN-6B01 surface-mount package and supports a supply voltage range from 1.75 V to 6 V. The device monitors two inputs with a threshold voltage of 1.47 V and an undervoltage threshold of 1.35 V. It provides an open-drain output and includes manual reset functionality via a push button. The reset delay time is fixed at 7.5 seconds, with an accuracy of 5%. Operating current is 45 uA, while static current is 10 nA. It functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Supports manual reset control through a dedicated push-button input for system reboot capabilities.
• Features dual-input monitoring architecture to supervise multiple voltage rails simultaneously.
• Delivers low quiescent current consumption suitable for battery-powered applications.

Supervisors Applications

• Push button reboot controllers in embedded systems
• Voltage supervision for portable electronic devices
• System reset management in industrial control units

Supervisors Procurement Notes

Verify the specific suffix 'BN258' corresponds to the required threshold voltage and package type during procurement. Confirm RoHS compliance status as indicated in official documentation. Ensure the USPN-6B01 footprint matches the PCB design. Check for any lead-free manufacturing certifications required by the target market regulations before finalizing orders.

Supervisors Selection Notes

Select this component when dual-channel voltage monitoring with manual override is required. The 1.47 V threshold suits applications needing precise supervision near lower voltage limits. Consider the 7.5 s reset delay for systems requiring extended stabilization periods. The low static current makes it appropriate for energy-constrained designs where standby power loss must be minimized.
