TPS3839K33DBZT Voltage Supervisor

The TPS3839K33DBZT from Texas Instruments is a high-precision voltage supervisor designed to monitor the supply voltage of digital systems. It ensures that microprocessors, microcontrollers, and other digital systems operate optimally by resetting these systems or holding them in a reset state whenever the supply voltage drops below a predetermined threshold. This particular model has a fixed-sense threshold voltage of 3.3V, making it suitable for systems that operate at this voltage level.

This voltage supervisor is characterized by its ultra-low power consumption, which is critical for battery-powered applications. With a typical quiescent current of only 150 nA, the TPS3839K33DBZT helps to extend the battery life of portable devices. Additionally, it features a very low threshold voltage hysteresis of 1%, which provides a precise monitoring and reset signal, ensuring reliable operation of the system.

The TPS3839K33DBZT comes in a compact, 3-pin SOT-23 package, making it an ideal choice for space-constrained applications. Its small footprint allows for easy integration into a wide range of products, from consumer electronics to industrial control systems. The device also offers a manual reset input, which provides designers with the flexibility to trigger a system reset from an external source if needed.

Key features of the TPS3839K33DBZT include:

• Fixed-sense threshold voltage: 3.3V
• Ultra-low quiescent current: 150 nA (typical)
• Low threshold voltage hysteresis: 1%
• Manual reset input
• Wide supply voltage range: 1.5V to 5.5V
• Fast response time
