Frequently Asked Questions

What is the reset threshold voltage of TPS3809L30DBVT?

The TPS3809L30DBVT has a fixed reset threshold voltage of 3.0V (nominal), with a minimum of 2.64V and maximum of 3.3V. When VCC falls below this threshold, the active-low RESET output asserts low to hold the system in reset.

What is the reset timeout period for TPS3809L30DBVT?

The TPS3809L30DBVT provides a minimum reset timeout of 200ms after VCC rises above the threshold voltage. This delay ensures that the power supply is fully stable before releasing the reset signal, preventing false starts in microcontroller applications.

What are typical applications for the TPS3809L30DBVT?

Typical applications include microcontroller supervisory circuits, power-on reset for DSPs, brownout detection in industrial control systems, IoT sensor nodes, handheld devices, and any embedded design requiring reliable 3.0V supply monitoring with minimal external components.

What is a suitable replacement or alternative for TPS3809L30DBVT?

Compatible alternatives include the TPS3839L30 (same threshold, lower quiescent current), MCP809 from Microchip (SOT-23, 2.93V threshold), and the MAX809 from Maxim Integrated. All offer similar push-pull active-low reset functionality in a 3-pin SOT-23 package.
