TPS3898PDRYT - Voltage Supervisor by Texas Instruments

The TPS3898PDRYT is a highly precise voltage supervisor designed to monitor VDD voltage levels and system integrity. Manufactured by Texas Instruments, this device is an essential component for reliable systems that require a watchdog for voltage supervision. It is commonly used in a variety of applications, including portable electronics, medical devices, automotive systems, and industrial controls.

Key Features

• High Accuracy: The TPS3898PDRYT provides a threshold voltage accuracy of 0.75% at 25°C, ensuring precise monitoring and control of system voltage levels.
• Low Quiescent Current: With a typical quiescent current of only 1.5 µA, this device is optimized for battery-powered and energy-efficient applications.
• Adjustable Threshold: The voltage threshold can be programmed via external resistors, allowing for flexibility in various application requirements.
• Manual Reset: The manual reset (MR) input enables users to trigger a system reset manually, providing additional control over the system's operation.
• Watchdog Timer: An integrated watchdog timer ensures that the system is functioning correctly and can initiate a reset if the timer is not serviced within a preset time interval.
• Power-On Reset (POR) Delay: The device features a programmable delay time for the power-on reset signal, ensuring that the system has stabilized before normal operation commences.

Specifications

Overall, the TPS3898PDRYT is a robust and flexible solution for systems that demand accurate voltage supervision to maintain operational integrity and prevent damage due to irregular voltage levels. Its small form factor and low power consumption make it an ideal choice for compact and power-sensitive designs.
