XC6135C27B9R-G

Supervisors Overview

The XC6135C27B9R-G is a supervisory circuit voltage detector manufactured by Torex Semiconductor. It operates within a supply voltage range of 1.1 V to 6 V and features a fixed threshold voltage of 2.7 V. The device utilizes an active low, open-drain output configuration and includes power failure detection capabilities. It is housed in a USPQ-4B05-4 surface-mount package and supports operation across a temperature range of -40°C to +105°C.

Supervisors Feature Summary

• Ultra-low power consumption with a typical operating current of 44 nA
• Separated sense pin design for independent voltage monitoring
• Integrated power failure detection functionality

Supervisors Applications

• Battery-powered portable electronic devices requiring extended standby life
• Embedded systems needing reliable voltage supervision under low-power conditions
• Industrial control circuits operating in wide temperature environments

Supervisors Procurement Notes

Verify the specific suffix B9R against the official Torex datasheet to confirm the exact threshold voltage and output type match your design requirements. Ensure the USPQ-4B05-4 footprint aligns with your PCB layout constraints. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a precise 2.7 V detection level is required for single-input monitoring. The open-drain output necessitates an external pull-up resistor for proper logic interface compatibility. Consider the 44 nA quiescent current as a critical factor for battery longevity in always-on applications compared to higher-current alternatives.

Supervisors Part Context

This part belongs to the XC6135 series of ultra-low power voltage detectors. The series offers various threshold options and packaging formats, including SOT-25-5 and USPQ variants. The C-series designation typically indicates CMOS output characteristics, while the N-series denotes open-drain outputs, though specific suffixes define the exact electrical parameters.

Supervisors Replacement Considerations

Cross-reference other XC6135 models with identical 2.7 V thresholds and open-drain outputs. Verify package compatibility between USPQ-4B05-4 and potential substitutes like SOT-25-5 variants if pinout adjustments are permissible in the design.
