Frequently Asked Questions
What is the reset threshold voltage of the TPS3106K33DBVR?
The TPS3106K33DBVR has a fixed reset threshold voltage of 3.3V. When the monitored supply drops below this threshold, the active-low RESET output is asserted to hold the system in reset, preventing erratic operation during undervoltage conditions.
What is the reset timeout period and why does it matter?
The TPS3106K33DBVR features a 200ms power-on reset timeout delay. After the monitored voltage rises above the 3.3V threshold, the device waits 200ms before deasserting the RESET signal, ensuring the power supply is fully stable before the microcontroller or DSP begins executing code.
What applications is the TPS3106K33DBVR best suited for?
This device is ideal for microcontroller reset supervision, DSP power management, battery-powered devices, and industrial control systems. Its dual-channel monitoring, compact SOT-23-6 package, and low quiescent current make it especially suitable for space-constrained and low-power embedded designs.
Is the TPS3106K33DBVR available in other package options or threshold voltages?
The TPS3106K33DBVR is offered in the SOT-23-6 (DBVR tape-and-reel) package with a fixed 3.3V threshold. Texas Instruments offers the TPS3106 family in multiple fixed threshold variants to match different supply rails, making it easy to find the right device for your system requirements.
