TPS3701DDCR

Comparators Overview

The TPS3701DDCR is a micro-power window comparator manufactured by Texas Instruments, designed for precise voltage monitoring in low-power applications. It operates within a supply voltage range of 1.8 V to 36 V and draws a typical quiescent current of 8 µA. The device features an open-drain output capable of sourcing up to 10 mA per channel. It provides a propagation delay of 28.1 µs and includes programmable delay functionality to prevent false triggering from transient voltage fluctuations. Housed in a compact SOT-23-6 package, it supports operation across a temperature range of -40°C to +125°C.

Comparators Feature Summary

• Window comparator architecture enables simultaneous over-voltage and under-voltage detection with configurable thresholds.
• Ultra-low power consumption ensures extended battery life in energy-constrained wireless sensor networks.
• Programmable delay feature filters out transient noise and prevents spurious alarms during power-up or voltage dips.

Comparators Applications

• Battery-powered wireless sensor networks requiring long-term voltage monitoring
• Portable electronic devices needing reliable power-fail detection
• Industrial systems utilizing supervisory circuits for fault protection

Comparators Procurement Notes

Verify the specific suffix 'DDCR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the required threshold voltages match the available factory-set options for this part number. Ensure compatibility with the target PCB footprint for the SOT-23-6 thin package. Check moisture sensitivity level (MSL) requirements for reflow soldering processes.

Comparators Selection Notes

Select the TPS3701DDCR when a single-channel window comparator with high input impedance and low static current is required. Compare against the TPS3700 series if a lower maximum supply voltage of 18 V is sufficient, as the TPS3701 supports up to 36 V. Consider the fixed threshold options available for this specific part number rather than adjustable variants.

Comparators Part Context

This component belongs to the TPS370x family of micro-power window comparators from Texas Instruments. It shares architectural similarities with the TPS3700 but offers an extended supply voltage range up to 36 V. The DDCR suffix indicates surface-mount packaging in a reel format, distinguishing it from cut-tape or tube variations within the same product line.

Comparators Replacement Considerations

The TPS3700DDCR serves as a functional substitute if the application does not require supply voltages exceeding 18 V. Verify that the threshold voltages and package dimensions are compatible before swapping components.
