Product Overview: TPS3808G125DBVRG4

The TPS3808G125DBVRG4 is a high-precision programmable delay supervisor from Texas Instruments, designed to provide reliable monitoring of voltage supply levels in electronic systems. This integrated circuit helps ensure that the system voltage remains within safe operating limits by resetting the system when it detects an undervoltage condition. The device is particularly suitable for a wide range of applications, including portable electronics, industrial control systems, and embedded applications where precise voltage supervision is critical.

Featuring a fixed-sense threshold voltage of 1.25V, the TPS3808G125DBVRG4 allows for close monitoring of the supply voltage. It also boasts a programmable delay time, which provides designers with the flexibility to set the reset timeout period according to their specific system requirements. This feature ensures that the system has sufficient time to stabilize before it is allowed to resume operation after a voltage fault is detected.

The TPS3808G125DBVRG4 comes in a compact 6-pin SOT-23 package, which is ideal for space-constrained applications. The small footprint of the device enables it to fit into tight PCB layouts, providing robust voltage supervision without compromising on board space.

Key features of the TPS3808G125DBVRG4 include:

• Manual reset input for direct control over the reset signal.
• Low quiescent current, making it suitable for battery-powered devices.
• Wide supply voltage range, accommodating various system voltages.
• High accuracy threshold voltage for precise monitoring.
• Open-drain RESET output, which allows for the flexibility in interfacing with other logic levels.

This voltage supervisor from Texas Instruments is designed with reliability in mind, offering features such as built-in glitch immunity to prevent false resets due to transient voltage spikes. With its combination of precision, programmability, and compact packaging, the TPS3808G125DBVRG4 is an excellent choice for engineers looking to enhance system reliability and safeguard against the consequences of undervoltage conditions.
