Description
The TPS3619-33DGKR is a Texas Instruments voltage supervisor with built-in watchdog functionality, designed for use in battery-powered and microprocessor-controlled systems. It provides device monitoring and reset generation to ensure system reliability. The component monitors the system's supply voltage and generates a reset signal when the voltage drops below a pre-defined threshold, ensuring that the microprocessor operates within safe voltage levels.
Key features include a precision fixed threshold voltage, a manual reset input, and a low supply current, making it energy-efficient for battery-operated devices. The watchdog timer function monitors system activity, sending a reset signal if regular microprocessor activity isn't detected within a specified timeframe. This helps in preventing system hangs and ensuring continuous operation. The TPS3619-33DGKR operates over a wide temperature range and is housed in a compact surface-mount package, making it suitable for space-constrained applications. It is widely used in consumer electronics, automotive systems, and industrial applications where reliability and efficient power management are critical.
