The TPS3839K33DQNT is a high-precision voltage supervisor designed and manufactured by Texas Instruments. This device is crucial for systems that require a reliable monitoring of the power supply voltage to ensure proper operation. The TPS3839K33DQNT is specifically designed to maintain system integrity by asserting a reset signal whenever the VCC supply voltage drops below a preset threshold.

Key Features

• Fixed Voltage Threshold: The device comes with a factory-programmed threshold voltage of 3.3V, which is ideal for a wide range of applications that operate at this common supply voltage.
• Ultra-Low Power Consumption: With a typical supply current of only 150 nA, the TPS3839K33DQNT is an excellent choice for battery-powered and portable applications where power efficiency is critical.
• Manual Reset Input: It includes a manual reset input that allows the user to trigger a system reset, providing additional control and flexibility.
• Reset Time Delay: The built-in delay ensures that the system has sufficient time to stabilize before the reset condition is de-asserted, thereby preventing false resets during transient conditions.
• Open-Drain Active-Low Reset: The device features an active-low, open-drain reset output that can be easily interfaced with other digital components.
• Temperature Range: This voltage supervisor operates over a wide temperature range of –40°C to +125°C, suitable for industrial and automotive applications.
• Small Package Size: Housed in a compact 5-pin SOT-23 package, the TPS3839K33DQNT saves valuable board space in space-constrained designs.

Applications

The TPS3839K33DQNT is versatile and can be used in a variety of applications, including:

• Microprocessor, microcontroller, or FPGA power monitoring
• Portable and battery-powered equipment
• Industrial controls
• Automotive systems
• Consumer electronics
• Data storage and servers

With its precision voltage monitoring and low power consumption, the TPS3839K33DQNT is an essential component for systems that require reliable operation under varying power conditions. Texas Instruments' commitment to quality ensures that this voltage supervisor meets the high standards required for professional electronic designs.
