TPS3808G01DRVR

The TPS3808G01DRVR is part of the PMIC - Supervisors family. It is an adjustable, precision, low-power voltage supervisor designed for power and battery-powered, microprocessor-based systems. It provides a small form factor, 1.16mm height and can be used in advanced system architectures, including on-chip core power reset, reset sequencing and monitoring, system voltage brown out, and many other protection functions.

The major application of TPS3808G01DRVR includes precision monitoring and resetting of processor cores, systems, and batteries to ensure data integrity, prevent incorrect operations, and extend system lifetime. In these and other related applications, it offers two reset outputs, a reset and a delayed reset, which are asserted when the monitored voltage drops below the adjustable threshold. When the monitored voltage rises above the threshold, the reset output is de-asserted and the delayed output is de-asserted after a set time period.

The TPS3808G01DRVR also provides a comparator output (COMP) pin, which is activated when the voltage at the monitored pin exceeds the set threshold. This pin can be used to monitor any point of a given system and report the application status to the microprocessor, helping it take appropriate actions. This makes the TPS3808G01DRVR very versatile in many applications.

The working principle of TPS3808G01DRVR is as follows. It has a voltage reference that sets an adjustable threshold at the comparator input. When the monitored voltage is lower than the adjustable threshold, the reset output is asserted and the delayed reset output is activated after a fixed delay. The comparator output (COMP) is activated when the monitored voltage is above the adjustable voltage threshold, which can be used to report the status to the system. It also provides advanced protection functions such as overvoltage, undervoltage and thermal protection, to ensure safe operation of the entire system.

To summarize, the TPS3808G01DRVR is specialized in precision monitoring and resetting of processor cores, systems, and batteries. It provides two reset outputs, a reset and a delayed reset, and a comparator output which is used to report the application status to the microprocessor. It has built-in features such as overvoltage, undervoltage, and thermal protection for safe operation. This makes it an ideal solution for applications that need advanced protection features.

The TPS3808G01DRVR is a versatile and reliable solution for many applications. It offers an adjustable, precision, low-power voltage supervisor, which makes it well-suited to a variety of applications. Its advantages make it a preferred choice for battery-powered and microprocessor-based systems.
