Frequently Asked Questions
What is the reset threshold voltage of the TLV809I50DBVT?
The TLV809I50DBVT has a fixed reset threshold of 5.0V. When the monitored supply voltage falls below this threshold, the device asserts an active-low RESET output to hold the system in reset until the voltage recovers and a timeout period elapses.
What package does the TLV809I50DBVT come in and what are its dimensions?
The TLV809I50DBVT is housed in a SOT-23-3 (3-pin) small-outline transistor package, also known as JEDEC TO-236. This package measures approximately 2.9mm x 1.6mm, making it ideal for space-constrained PCB layouts in portable and embedded applications.
What are typical applications for the TLV809I50DBVT?
The TLV809I50DBVT is commonly used in microcontroller reset circuits, embedded processor boards, industrial control systems, battery-powered devices, and IoT nodes. It ensures the processor stays in reset during power-up until the 5V supply is stable, preventing erratic system behavior.
Can the TLV809I50DBVT be used as a replacement for other voltage supervisor ICs?
Yes, the TLV809I50DBVT is pin-compatible with many standard 3-pin voltage supervisors from other manufacturers such as the MAX809 and MCP100 series with a 5.0V threshold. Always verify the reset timeout period, threshold accuracy, and output type before substituting in your design.
