Frequently Asked Questions
What is the reset threshold voltage of the TPS3809K33MDBVREP?
The TPS3809K33MDBVREP has a fixed reset threshold voltage of 2.93V, designed to monitor 3.3V supply rails. When the supply voltage drops below this threshold, the active-low RESET output is asserted to hold the system in reset until the voltage recovers.
What package does the TPS3809K33MDBVREP come in?
The TPS3809K33MDBVREP is available in a SOT-23 3-pin (R-PDSO-G3) package, which is an ultra-compact surface-mount package ideal for space-constrained designs. It requires minimal PCB area while providing reliable voltage supervision functionality.
What does the 'EP' (Enhanced Product) designation mean for TPS3809K33MDBVREP?
The 'EP' designation indicates Enhanced Product grade, meaning Texas Instruments guarantees a minimum 15-year product life cycle (YTEOL: 15) and extended manufacturing support. This is critical for industrial, automotive, and medical applications that require long-term component availability and supply chain stability.
What are typical applications for the TPS3809K33MDBVREP?
The TPS3809K33MDBVREP is commonly used in microprocessor supervisory circuits, embedded systems, industrial controllers, and automotive electronics. It monitors 3.3V power rails and generates a reset signal to prevent system errors during voltage fluctuations, brownouts, or power-up sequences.
