Product Overview: TPS3851G33EQDRBRQ1 from Texas Instruments

The TPS3851G33EQDRBRQ1 is a highly precise voltage supervisor with a programmable window-watchdog timer, designed and manufactured by Texas Instruments (TI). This integrated circuit is tailored to meet the stringent requirements of automotive and industrial applications, ensuring systems operate within their voltage thresholds and providing reliable monitoring to prevent system failure.

Key Features

• Voltage Supervision: The device offers a fixed 3.3V voltage threshold precision of 0.25% at 25°C, which is crucial for sensitive electronics that require stable and accurate voltage levels.
• Programmable Window-Watchdog Timer: The watchdog timer is fully programmable, allowing designers to set specific timeout periods that suit their application needs, enhancing system reliability and preventing malfunctions.
• Power-On Reset (POR) Delay: The TPS3851G33EQDRBRQ1 provides a programmable power-on reset delay, which ensures that the system has stabilized before normal operation begins.
• Manual Reset (MR) Input: A dedicated manual reset input allows for an external trigger to initiate a system reset, offering additional control and safety mechanisms.
• Low Quiescent Current: With a low quiescent current, the device is suitable for power-sensitive applications, minimizing the power consumption when the device is in an idle state.
