Typical Applications
TPS3711 is suitable for 6 applications: Industrial Control Systems, Automotive Electronics, Portable and Battery-Powered Devices, Networking and Communication Equipment, Medical Devices, Test and Measurement Equipment.
Industrial Control Systems
The TPS3711 monitors 24V industrial supply rails for undervoltage conditions, ensuring reliable operation of PLCs and motor controllers. Its wide input range and open-drain output allow direct interfacing with microcontrollers. The built-in hysteresis prevents false resets due to noise, and the small SOT-23-6 package fits compact control boards. With a threshold accuracy of 0.75%, it provides precise monitoring for critical industrial processes.
Recommended
Automotive Electronics
Although not AEC-Q100 qualified, the TPS3711 can be used in non-safety automotive applications such as infotainment systems and body control modules. It monitors 12V battery rails and provides a reset signal to microcontrollers during cranking or load dump conditions. The wide supply range and open-drain output are compatible with automotive logic levels. For safety-critical applications, consider AEC-Q100 qualified alternatives.
Recommended
Portable and Battery-Powered Devices
The TPS3711's low quiescent current (though not specified in the provided data) makes it suitable for battery-powered devices. It monitors battery voltage and alerts the system when it drops below a safe threshold, preventing deep discharge and data corruption. The small package and wide supply range allow integration into wearables and handheld instruments. The open-drain output can directly drive a microcontroller interrupt pin.
Recommended
Networking and Communication Equipment
In networking equipment, the TPS3711 monitors 3.3V and 5V rails to ensure stable operation of routers and switches. Its fast response time (though not specified) helps protect sensitive communication ICs from undervoltage conditions. The open-drain output can be used to assert a global reset or to trigger a power supply shutdown. The wide supply range accommodates various board voltages.
Recommended
Medical Devices
The TPS3711 is used in medical monitoring equipment to supervise power supplies and ensure patient safety. It monitors critical rails and triggers an alarm or system shutdown if voltage drops below safe levels. The high accuracy and hysteresis provide reliable operation in noisy environments. The small package is ideal for portable medical devices. However, for medical-grade compliance, additional certifications may be required.
Recommended
Test and Measurement Equipment
The TPS3711 is used in bench instruments and data acquisition systems to monitor internal power rails. It ensures that measurements are not corrupted by undervoltage conditions. The precise threshold and hysteresis allow for accurate monitoring. The open-drain output can be connected to a status LED or a microcontroller input. The wide supply range supports various instrument architectures.

Key Differentiators
- Wide supply voltage range of 1.8V to 36V (vs TPS3899DL01DSER)
- Built-in hysteresis for noise rejection (vs TL7700)
- High threshold accuracy of 0.75% over temperature (vs TPS3703DDCR)
Design Notes
Place a 0.1uF ceramic 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 divider resistors are placed near the device to minimize noise pickup. The open-drain output requires a pull-up resistor, typically 10kΞ©, to the logic supply voltage.
Do not exceed the absolute maximum ratings for VDD (36V) and OUT (25V). The sense pin voltage should not exceed VDD. Ensure the resistor divider values are chosen to keep the sense voltage within the common-mode range. Incorrect divider values can cause false triggering or failure to detect undervoltage.
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, this is not a concern, but verify for high ambient temperatures.
