The TPS3839K50DQNT is a high-precision voltage supervisor designed by Texas Instruments to monitor system voltages, ensuring that microprocessors (µP), microcontrollers (MCU), and other voltage-sensitive components operate optimally. This integrated circuit (IC) is particularly well-suited for portable and battery-powered applications due to its ultra-low power consumption and small footprint.

Key Features

• Voltage Threshold: The device features a fixed-sense threshold voltage of 5.0V, which provides a reliable reset signal to the host system whenever the monitored voltage falls below this preset threshold.
• Low Quiescent Current: With a typical quiescent current of only 350 nA, the TPS3839K50DQNT is an excellent choice for power-sensitive designs, helping to extend battery life and reduce overall power consumption.
• High Accuracy: This voltage supervisor offers a high threshold accuracy of ±1%, ensuring precise monitoring and control of system voltages, even in critical applications.
• Fast Propagation Delay: The device boasts a fast propagation delay of typically 20 µs, which allows for quick system response to under-voltage conditions.
• Manual Reset Input: A manual reset input is provided, giving users the ability to initiate a system reset manually, which is useful for debugging and testing purposes.
• Temperature Range: The TPS3839K50DQNT operates over a wide temperature range of -40°C to +125°C, making it suitable for use in harsh environmental conditions.
