TPS3808G15DBVT

TPS3808G15DBVT is a over, under and brownout voltage supervisor series from Texas Instruments, this series provide overvoltage, undervoltage, and brownout protection in an integrated, small form factor device with minimal external circuitry. This series can be used to monitor power supplies, provide undervoltage lockout (UVLO), provide safety system reset and provide fixed processor level reset.

TPS3808G15DBVT series work in the voltage range of 2.8 V - 5.5 V, with high accuracy of 0.9V, 0.8V, and 0.6V, respectively. It features high ESD protection up to 8kV, as well as a wide temperature range of -40°C to 125°C, making it suitable for harsh application environments. The TPS3808G15DBVT series is available in the industry-standard 8-pin SOIC package and operates from a single 3 V or 5 V supply and provides an active-low reset output.

The TPS3808G15DBVT series are ideal for monitoring voltage rail in handheld and battery-powered system, or other space-limited applications. It can also be used to monitor system power in datacom and telecom systems, e.g. servers and storage, or embedded systems including automotive, industrial and medical for reset protection.

The operating principle of the TPS3808G15DBVT is based on the voltage threshold detection circuitry. It provides the three octets window with two threshold voltages which allows two independent settings of under- and overvoltage (UV/OV). Additionally, a third threshold level setting allows brownout protection. If the monitored voltage falls below the undervoltage threshold (UV), then the UV reset output will be asserted and goes to active low. If the voltage rises above the overvoltage threshold (OV), then the OV reset output will be asserted and goes to active low. It also features an adjustable delay accuracy of ±30 ms, delay time up to 500 ms, manual reset and power-on reset push button.

The TPS3808G15DBVT is supported by the most popular software tools, such as the Windows-based graphical user interface from Texas Instruments (GUI) and other integrated design environments (IDEs) including the IAR Embedded Workbench, Debugging Tools, Flash Programming Tools, and more. Furthermore, the TPS3808G15DBVT series can be used in extreme environmental conditions because of its -40°C to 125°C temperature range.

In conclusion, the TPS3808G15DBVT series provides over-voltage, undervoltage, and brownout protection in an integrated, small form factor device with minimal external circuitry. It is able to monitor voltage rail in handheld and battery powered system, or other space-limited applications. It is also suitable for a variety of extreme environmental conditions due to its wide temperature range. It is supported by the most popular software tools, making it perfect for monitoring system power in datacom and telecom systems, or for reset protection in embedded systems such as automotive, industrial, and medical applications.
