TPS3702CX10QDDCRQ1

Supervisors Overview

The TPS3702CX10QDDCRQ1 is an automotive-grade high-accuracy voltage monitor designed for overvoltage and undervoltage detection. It operates within a supply voltage range of 1.8 V to 18 V and features a fixed threshold of 1.0 V with 0.25% accuracy. The device provides an active-low open-drain output and consumes 7 µA of quiescent current. It is qualified to AEC-Q100 standards, supports a chip enable function, and operates reliably across a temperature range of -40°C to +125°C in a TSOT-23-6 package.

Supervisors Feature Summary

• Provides high-accuracy monitoring for overvoltage and undervoltage conditions with fixed threshold settings
• Features low power consumption suitable for battery-operated automotive applications
• Includes a chip enable pin for power management control

Supervisors Applications

• Automotive systems requiring precise voltage supervision
• Low-voltage supply rail monitoring with narrow tolerance margins
• Battery-powered electronic modules needing undervoltage protection

Supervisors Procurement Notes

Verify the specific suffix 'QDDCRQ1' matches the required automotive qualification (AEC-Q100) and package type (TSOT-23-6). Confirm the fixed threshold voltage corresponds to the system's critical trip point requirements. Ensure compatibility with the target operating temperature range and supply voltage limits before integration into production designs.

Supervisors Selection Notes

Select this component when a fixed, high-precision voltage threshold is required without external resistor programming. It is suitable for applications where low quiescent current is critical for extending battery life. Consider the open-drain output configuration for interfacing with various logic levels. Verify that the fixed 1.0 V threshold aligns with the monitored circuit's operational limits.

Supervisors Part Context

This part belongs to the TPS3702 family of high-accuracy voltage monitors from Texas Instruments. The 'Q' prefix indicates automotive qualification, while 'CX10' specifies the fixed 1.0 V threshold variant. The 'DDCR' denotes the TSOT-23-6 thin package and reel packaging format. This series is designed for robust performance in demanding automotive environments.

Supervisors Replacement Considerations

Check for other TPS3702 variants with different fixed thresholds if the 1.0 V setting is unsuitable. Compare with TPS3700 or TPS389 series devices for alternative channel counts or programmable options. Ensure any substitute maintains AEC-Q100 qualification and compatible package dimensions for direct replacement.
