Product Overview: TPS3808G15DBVR by Texas Instruments

The TPS3808G15DBVR is a high-precision programmable delay supervisor from Texas Instruments, designed to provide reliable monitoring of system voltages. This device is part of the TPS3808 family of voltage supervisors that are known for their ultra-low power consumption and small form factor, making them ideal for a wide range of applications including portable and battery-powered electronics.

This particular model, the TPS3808G15DBVR, comes in a compact 6-pin SOT-23 package, which is suitable for space-constrained applications. It features a fixed-sense threshold voltage of 1.5V, which is precision-trimmed to ensure accurate monitoring of the supply voltage. The device offers a programmable time delay, which allows designers to set the reset timeout period according to the specific needs of their system, thereby providing additional flexibility and protection.

One of the key attributes of the TPS3808G15DBVR is its ultra-low quiescent current of just 2.5 µA (typical), which minimizes power consumption when the device is in active operation. This characteristic is particularly beneficial for battery-operated devices where power efficiency is critical. The device also includes a manual reset input, which enables a system reset to be triggered with an external signal, providing an additional layer of control to the system designer.

The TPS3808G15DBVR also boasts a wide operating temperature range of -40°C to +125°C, ensuring reliable performance across diverse environmental conditions. With built-in over-temperature and under-voltage lockout features, the device ensures that the system is protected against abnormal operating conditions, thereby improving the overall system reliability.

In summary, the TPS3808G15DBVR by Texas Instruments is a highly reliable and versatile voltage supervisor that combines precision voltage monitoring with low power consumption and a programmable delay feature. It's suitable for a variety of applications, including portable devices, industrial controls, and other systems that require efficient voltage supervision.
