TPS3808G30DBVTG4

Supervisors Overview

The TPS3808G30DBVTG4 is a low quiescent current supervisory circuit from Texas Instruments, designed to monitor a single voltage input. It features a fixed threshold voltage of 2.79 V and an overvoltage threshold of 2.803 V. The device provides an active-low, open-drain output with a manual reset function. Reset delay time is programmable, ranging from 1.25 ms to 10 s. It operates within a supply voltage range up to 6.5 V and maintains accuracy of 0.5%. The component supports surface mount installation in a SOT-23-6 package and functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Low quiescent current consumption for power-sensitive applications
• Programmable reset delay time allowing flexible timing control
• Manual reset capability for system initialization control
• High accuracy voltage monitoring with defined threshold levels

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered portable devices
• Embedded systems requiring reliable reset signals
• Industrial control circuits

Supervisors Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the exact threshold voltage corresponds to the G30 variant (2.79 V) rather than other TPS3808 subtypes. Ensure the SOT-23-6 package matches your PCB footprint requirements. Check for any obsolescence notices or PCN updates regarding this specific part number before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.79 V threshold is required for monitoring a single rail. The programmable delay feature allows customization of reset timing without external components. Consider the low quiescent current if battery life is critical. Ensure the operating temperature range meets your environmental specifications. Compare against other TPS3808 variants if different threshold voltages are needed.

Supervisors Part Context

This part belongs to the TPS3808 family of microprocessor supervisory circuits. The family offers various threshold voltages and packaging options. The G30 designation specifies the 2.79 V threshold version. The DBVT suffix indicates the SOT-23-6 surface-mount package. The G4 suffix typically denotes lead-free and RoHS-compliant manufacturing.

Supervisors Replacement Considerations

Direct replacements include other TPS3808 variants with similar thresholds or the TPS3808G30DBVR for tape-and-reel packaging. Verify pin compatibility and electrical parameters before substitution. Consult Texas Instruments for recommended alternatives if the G30DBVTG4 is discontinued.
