TPS3710-Q1

The TPS3710-Q1 is a high-precision, low-power voltage supervisor designed for automotive and industrial applications requiring robust power management. It monitors supply voltages with an accurate threshold of 2.93 V (typical) and includes a 1.25 µs timeout period for reliable system reset functionality. The device operates over a wide supply range from 2.7 V to 5.5 V, making it suitable for various battery-powered and regulated systems. This supervisor features a push-pull output that can source or sink up to 15 mA, enabling direct control of microcontrollers, relays, or other digital loads without additional drivers. Its ultra-low quiescent current—less than 1.5 µA in normal operation—ensures minimal power consumption, which is critical for energy-sensitive designs such as remote sensors or IoT devices. The TPS3710-Q1 also incorporates a built-in delay timer that prevents false resets due to transient voltage dips, enhancing system stability under noisy conditions. Designed for automotive use, the device meets AEC-Q100 Grade 1 qualification, ensuring reliability in harsh environments with operating temperatures from –40°C to +125°C. It includes a manual reset input (MR) that allows external assertion of the reset signal, providing flexibility for system-level control. Additionally, the part supports open-drain and push-pull output modes via a pin-selectable configuration, offering design versatility across different application needs. Common applications include automotive ECUs, battery management systems, industrial controllers, and portable electronics where precise voltage monitoring and efficient power usage are essential. Its ability to detect undervoltage conditions and initiate a controlled reset ensures safe shutdown and restart sequences, reducing the risk of data corruption or hardware damage. The TPS3710-Q1 is available in a compact 5-pin SOT-23 package, simplifying integration into space-constrained designs while maintaining high performance and thermal efficiency.
