The TPS3808G15DRVR is a single-channel, adjustable voltage supervisor that monitors power-supply and battery voltages, and provides performance-enhancing and system-level protection. This device is part of the general purpose Power Management Integrated Circuit (PMIC) family, specifically designated as one of the Supervisors.

A supervisor is a type of PMIC that monitors the system power supply, as well as other voltages, and takes corrective action to ensure that the system operates safely and reliably. This is a critical aspect of system operation as it can prevent damage caused by power-supply faults or other abnormalities. Supervisors have a wide range of features designed for system optimization and protection.

The TPS3808G15DRVR is an adjustable voltage supervisor that operates from a 2.9V to 5.5V supply voltage. It has an adjustable threshold voltage and an adjustable tolerance window. It provides a reset output that goes active when the monitored voltage drops below the acceptable threshold window. This device can also be configured so that the reset is delayed at power-on while the monitored voltage reaches the acceptable threshold. This feature can be used to delay the reset until after the power supply has stabilized.

The TPS3808G15DRVR is designed to operate in hostile environments, with a 5 ns glitch filter and a 0.5ms reset timer designed to protect against false signals due to noise or power supply transients. It also features overtemperature protection to ensure system safety in extreme operating conditions. The reset output is active-low with an open-drain output.

The TPS3808G15DRVR can be used in a variety of applications, such as for automotive and battery-powered systems, to monitor the power supply and inactive system voltages. It can also be used for processors, microcontrollers and logic ICs, and integrated into power-supply systems to improve system reliability and performance. The adjustable threshold also makes it ideal for digital-power applications.

Overall, the TPS3808G15DRVR is an accurate, efficient voltage supervisor that provides added reliability, system performance and power savings. With its adjustable threshold and tolerance window, open-drain reset output, robust noise and transient protection, and support for extreme operating conditions, it is an ideal PMIC for a range of applications.
