Texas Instruments TPS3703F6050DSER

Overview

TPS3703F6050DSER from Texas Instruments is a high-accuracy window voltage supervisor IC with integrated overvoltage (OV) and undervoltage (UV) detection, ±0.7% threshold accuracy over –40°C to +125°C, 7 µA max quiescent current, and dual fixed/programmable reset time delay (1 ms / 20 ms). It monitors low-voltage rails in industrial processors and power management systems where narrow supply margins demand precise fault detection.

For engineers reviewing the TPS3703F6050DSER datasheet, TPS3703F6050DSER pinout, TPS3703F6050DSER application, or TPS3703F6050DSER equivalent, key selection criteria include its 6-pin WSON package, UV/OV window thresholds of 0.6 V (UV) and 0.5 V (OV), CT-pin programmable timing, open-drain RESET output, and manual reset (MR) support for system sequencing.

Technical Context

The TPS3703F6050DSER implements dual precision comparators with an internal trimmed resistor divider and reference, eliminating external resistors and enabling ±0.7% total threshold accuracy across temperature. Its architecture supports independent OV and UV trip points with built-in hysteresis (0.3–0.8% of threshold) and glitch immunity (≥3.5 µs at 5% overdrive).

Reset timing is determined by the CT pin configuration: floating CT selects 1 ms delay, CT pulled to VDD via 10 kΩ selects 20 ms delay, and CT connected to ground via capacitor enables user-programmable delays from ~50 µs to >2 s. The MR input provides asynchronous reset assertion with 1 µs minimum pulse width and 500 ns propagation delay.

FAQ

What is the exact UV and OV threshold configuration for TPS3703F6050DSER?

The TPS3703F6050DSER is configured as a fixed window supervisor with undervoltage threshold (VIT−) of 0.6 V and overvoltage threshold (VIT+) of 0.5 V - meaning it asserts RESET when the SENSE voltage falls below 0.6 V OR rises above 0.5 V. This asymmetric window is confirmed in TI's device nomenclature guide and Electrical Characteristics table for the F6050 variant.

How does the CT pin determine reset delay in TPS3703F6050DSER?

In TPS3703F6050DSER, the CT pin selects between two factory-programmed delays: floating CT configures 1 ms delay, while connecting CT to VDD via 10 kΩ resistor configures 20 ms delay. No external capacitor is required for these modes. Capacitor-based programming is supported but not default - the "F" suffix denotes fixed-delay variants.

Does TPS3703F6050DSER require external resistors to set thresholds?

No. The TPS3703F6050DSER integrates precision trimmed resistors and a bandgap reference, so no external resistors are needed to configure its 0.6 V UV / 0.5 V OV thresholds. This eliminates resistor tolerance errors, reduces PCB area, and improves long-term accuracy stability - a key differentiator versus discrete supervisor solutions.

What is the maximum operating temperature range for TPS3703F6050DSER?

The TPS3703F6050DSER is rated for operation from –40°C to +125°C ambient temperature, with guaranteed ±0.7% threshold accuracy across this full range. Its thermal resistance (RθJA = 184.2°C/W) and low 7 µA max quiescent current ensure reliable performance in sealed enclosures and high-density industrial modules.

Can TPS3703F6050DSER monitor a supply rail different from its own VDD?

Yes. TPS3703F6050DSER supports independent supply monitoring: VDD powers the IC (1.7–5.5 V), while SENSE monitors a separate rail (0–5.5 V). This enables monitoring of higher-voltage rails (e.g., 12 V DC bus) using a resistive divider into SENSE, or low-noise core rails directly - a capability confirmed in the Functional Block Diagram and Pin Functions section.
