TPS3703A7330DSERQ1

Supervisors Overview

The TPS3703A7330DSERQ1 is an automotive-grade overvoltage and undervoltage reset IC designed for monitoring single voltage rails. It features a high-accuracy window supervisor with a threshold voltage of 3.3 V and a reset delay time of 200 ms. The device supports a maximum supply voltage of 5.5 V and operates within a temperature range of -40°C to +125°C. It utilizes a WSON-6 package (1.5x1.5 mm) and provides an active low, open drain output. The component includes manual reset functionality without a watchdog timer or battery backup switch.

Supervisors Feature Summary

• Integrated overvoltage and undervoltage monitoring with high accuracy
• Compact industry smallest 6-pin DSE package design
• Automotive-grade reliability for harsh environments

Supervisors Applications

• Automotive electronic control units
• Single voltage rail supervision in vehicles
• Overvoltage protection circuits

Supervisors Procurement Notes

Verify the specific suffix 'Q1' confirms automotive qualification status. Ensure the 'DSE' package code matches the required WSON-6 footprint dimensions. Confirm the '7330' designation aligns with the 3.3 V threshold requirement for the target application voltage rail. Cross-reference the manufacturer datasheet revision date to ensure compatibility with current design specifications.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with precise 3.3 V threshold detection is required. The choice is driven by the need for automotive-grade operation across extended temperature ranges. Consider the small form factor for space-constrained PCB layouts. Verify that the open-drain output configuration suits the system logic levels and pull-up requirements.

Supervisors Part Context

This part belongs to the Texas Instruments TPS3703-Q1 family of supervisors. The family offers various threshold voltages and configurations for automotive applications. The TPS3703 series is distinguished by its compact size and high accuracy, making it suitable for modern vehicle electronics requiring reliable power management.

Supervisors Replacement Considerations

Check for other TPS3703 variants with different threshold voltages if the 3.3 V setting does not match the new design. Verify pinout compatibility with existing footprints before substituting.
