Product Description

The TPS3824-50QDBVRQ1 is an Automotive voltage supervisor designed to monitor power supply stability in harsh automotive environments. It integrates a Watchdog timer reset function to ensure system reliability by detecting microcontroller operation faults. This device operates within a 1.5V to 5.5V input range, supporting direct connection to 5V or lower voltage rails. It features a fixed 4.5V threshold for voltage supervision and includes a manual reset input. Operating across -40°C to +125°C, it complies with AEC-Q100 standards for automotive applications like ECUs and advanced driver-assistance systems. Advantages include ultra-low quiescent current (1.5µA typical) and immunity to voltage transients, while the fixed threshold limits configurability. The watchdog timer requires periodic toggling via a microcontroller GPIO to maintain system operation. Packaged in SOT-23-5, it enables compact designs without external components for basic monitoring functions.
