What are the key features of TPS3808G15DBVTG4?
- Programmable reset delay via external capacitor allows the hold-off time to be tailored to the specific power-supply settling requirements of the target system
- Fixed 1.5 V monitoring threshold simplifies design for low-voltage microcontroller and FPGA core supply rails
- Single-channel voltage supervisor in a 6-pin SOT-23 package minimizes PCB footprint for space-constrained embedded designs
- RoHS-compliant lead-free construction (JESD-609 code e4) meets global environmental regulations for electronics manufacturing
What is TPS3808G15DBVTG4 used for?
The TPS3808G15DBVTG4 is designed for microcontroller and DSP power-on reset applications where the 1.5 V core supply must be fully settled before the processor begins executing code. Its programmable delay is particularly valuable in systems with slow-rising power rails or where downstream logic requires a guaranteed quiet period after supply stabilization. The compact SOT-23 package makes it an efficient solution for portable consumer electronics, IoT nodes, and industrial control cards with tight board space constraints.

Frequently Asked Questions
What supply voltage does the TPS3808G15DBVTG4 monitor?
The TPS3808G15DBVTG4 monitors a fixed 1.5 V supply rail. When the monitored voltage falls below the 1.5 V threshold, the device asserts its active-low reset output, holding the connected microcontroller or logic device in reset until the supply recovers and the programmed delay period completes.
How is the reset delay programmed on the TPS3808G15DBVTG4?
The reset time delay is set by connecting an external capacitor to the CT pin. The capacitor value determines how long the reset output remains asserted after the supply voltage returns above the threshold, allowing designers to customize the hold-off time to match the power-supply settling time of their specific system.
Does the TPS3808G15DBVTG4 include a watchdog timer or manual reset?
No. The TPS3808G15DBVTG4 is a simple voltage supervisor without a watchdog timer, manual reset input, or overvoltage detection. It is a single-function device focused solely on undervoltage monitoring with programmable reset delay, keeping the design minimal and the package pin count at six.
Is the TPS3808G15DBVTG4 RoHS compliant?
Yes. The G4 suffix and JESD-609 code e4 confirm that the TPS3808G15DBVTG4 is fully RoHS compliant and lead-free. The plastic/epoxy package body meets global hazardous substance regulations, making it suitable for consumer, industrial, and commercial electronics manufactured for international markets.
What are typical applications for the TPS3808G15DBVTG4?
The device is commonly used to supervise the 1.5 V core supply of microcontrollers, FPGAs, and DSPs in embedded systems, ensuring a clean power-on reset sequence. It is also used in multi-rail power sequencing designs where each rail has a dedicated supervisor, and in battery-powered IoT devices where reliable startup after deep sleep cycles is required.
