XC6124D519MR-G

Supervisors Overview

The XC6124D519MR-G is a CMOS voltage detector manufactured by Torex Semiconductor Ltd, housed in an SOT-25-5 surface-mount package. It features a detection threshold voltage of 5.19 V and operates within a supply voltage range of 1 V to 6 V. The device includes a built-in watchdog timer with a reset delay time of 100 ms. It draws a typical operating current of 12 uA and a standby current of 5 uA. The output type is CMOS open drain, and it supports battery backup switching. The component functions reliably across an ambient temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer function for system stability monitoring
• Includes a dedicated battery backup switch terminal
• Provides an open-drain output compatible with CMOS logic levels

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated equipment needing backup power management
• Embedded systems utilizing watchdog timer functionality

Supervisors Procurement Notes

Verify the specific suffix MR-G confirms the SOT-25-5 package and tape-and-reel delivery format. Confirm the threshold voltage code D519 corresponds to the required 5.19 V detection level for your circuit design. Ensure compatibility with the 1 V to 6 V input range and check RoHS compliance status before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a precise 5.19 V detection threshold is required alongside integrated watchdog capabilities. The low standby current of 5 uA makes it suitable for energy-constrained applications. Verify that the open-drain output configuration aligns with the downstream logic requirements and that the SOT-25-5 footprint fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the XC6124 series of voltage detectors from Torex Semiconductor. The series utilizes advanced CMOS technology to achieve high accuracy and low power consumption. The XC6124 family typically offers various threshold voltages and functional combinations, including watchdog timers and manual reset options, packaged in compact surface-mount formats for space-sensitive designs.

Supervisors Replacement Considerations

Cross-reference with other XC6124 variants sharing the same watchdog and backup features but differing only in threshold voltage codes if the 5.19 V level is adjustable. Verify pinout compatibility with SOT-25-5 packages from other manufacturers before substitution.
