Typical Applications
TPS3711 is suitable for 6 applications: Industrial Control Systems, Automotive Electronics, Portable Devices, Networking Equipment, Medical Devices, Test and Measurement.
Industrial Control Systems
The TPS3711 monitors 24V supply rails in industrial control systems, ensuring that microcontrollers and PLCs are held in reset until the supply is stable. Its wide input range (1.8V to 36V) and high accuracy (0.75%) prevent false resets during brown-out conditions. The open-drain output can directly drive reset inputs or logic gates, simplifying interface design. Built-in hysteresis provides noise immunity in electrically noisy factory environments. The SOT-23-6 package fits compact PLC modules and sensor interfaces.

Key Differentiators
- Wide supply voltage range of 1.8V to 36V (vs TPS3899DL01DSER)
- Fixed 400mV internal reference with 0.75% accuracy (vs TPS3700)
- Open-drain output rated to 25V (vs TPS3703)
Design Notes
Place a 0.1uF decoupling capacitor close to the VDD pin to filter high-frequency noise. The SENSE pin should be connected to the monitored voltage through a resistor divider. Ensure the resistor values are chosen to set the desired threshold voltage, considering the 400mV reference and hysteresis.
The open-drain output requires an external pull-up resistor. Choose the pull-up resistor value based on the logic voltage and the desired output rise time. A typical value is 10kOhm. Ensure the pull-up voltage does not exceed the 25V rating of the output.
The TPS3711 has low power dissipation, but in high-temperature environments, ensure the junction temperature does not exceed 125Β°C. The SOT-23-6 package has a thermal resistance of approximately 200Β°C/W. For most applications, no heatsinking is required.
