Product Overview: TPS3808G19DBVR from Texas Instruments

The TPS3808G19DBVR is a high-precision programmable delay supervisor from Texas Instruments, designed to provide reliable monitoring for microprocessor (μP), microcontroller (MCU), and digital signal processor (DSP) systems. This device is a critical component for systems that require precise voltage monitoring and timed reset control to ensure proper operation and system stability.

Key Features

• Voltage Supervision: The TPS3808G19DBVR monitors the supply voltage (VDD) and asserts a reset signal if it falls below the programmable threshold voltage, helping to prevent system failure due to power issues.
• Programmable Delay: It offers a programmable time delay for the reset signal, allowing designers to tailor the reset timing to the specific needs of their system.
• Low Quiescent Current: With a low quiescent current of 3 μA (typical), this device is suitable for power-sensitive applications.
• Manual Reset: An additional manual reset input provides a means to initiate a system reset independently of the voltage monitoring function.
• Temperature Range: The device operates over a wide temperature range, making it suitable for various industrial and commercial applications.
