TPS3839E16DBZT - Ultra-Low-Power Supply Voltage Supervisor

The TPS3839E16DBZT is a high-precision voltage supervisor designed by Texas Instruments, crafted to monitor system voltages and ensure consistent performance in a variety of electronic applications. This component is a crucial part of any power management system, providing a reliable solution for systems that require a stringent power-on reset control.

This voltage supervisor operates over a wide supply voltage range and is optimized for low-power operations. It features a fixed-sense threshold voltage of 1.6V, which is meticulously designed to monitor the supply voltage of microcontrollers, microprocessors, and other voltage-sensitive components. When the monitored supply voltage drops below the threshold, the TPS3839E16DBZT asserts a reset signal, which remains asserted until the voltage recovers above the threshold, plus a minimum hysteresis. This ensures a proper system reset and helps prevent system malfunctions due to inadequate supply voltages.

One of the standout features of the TPS3839E16DBZT is its ultra-low quiescent current of just 150 nA (typical), making it an ideal choice for battery-powered and portable applications where power conservation is critical. The device is also characterized for operation over a temperature range of –40°C to +125°C, allowing it to function reliably in a variety of environmental conditions.

The TPS3839E16DBZT comes in a small, 3-pin SOT-23 package, which is suitable for space-constrained applications. The small footprint of the package allows for a compact PCB layout, which is beneficial for modern, miniaturized electronic designs.

Key features of the TPS3839E16DBZT include:

• Fixed-sense threshold voltage of 1.6V
• Ultra-low current consumption of 150 nA (typical)
• Manual reset input
• Power-on reset generator with fixed delay time of 200 ms (minimum)
• Wide supply voltage range
• High accuracy over temperature
• Available in a small SOT-23 package

Overall, the TPS3839E16DBZT from Texas Instruments is an essential component for any application requiring a reliable and energy-efficient voltage supervision solution. Its precise voltage monitoring capabilities, coupled with its low power consumption, make it a versatile choice for a wide range of electronic systems.
