TPS3851G33EDRBR Typical application Circuitry

The TPS3851G33EDRBR is a high-accuracy voltage supervisor with an integrated window watchdog timer from Texas Instruments (TI). It is part of the TPS3851 series. This device is designed for applications requiring precise voltage monitoring and watchdog features to detect system anomalies.

Description:

The TPS3851 combines a precision voltage supervisor with a programmable window watchdog timer. The voltage supervisor monitors a system voltage and asserts a reset signal if this voltage moves outside a specified window. The watchdog timer, on the other hand, checks for system anomalies by ensuring the system provides regular feedback within expected time intervals.

Key Features:

1. Voltage Threshold: The TPS3851G33 variant is tailored for a 3.3V supply, as indicated by the "G33" in its part number.

2. Integrated Window Watchdog Timer: The TPS3851 includes a programmable window watchdog timer. If the system being monitored does not "kick" or service the watchdog within a specified window, the watchdog will trigger a system reset.

3. Reset Output: This output becomes active (typically going low) if the monitored voltage moves outside the specified window or when the watchdog timer is not serviced in its defined window. It remains active for a predetermined timeout period.

4. Manual Reset (MR): This feature allows an external source, like a push-button or another controller, to trigger a system reset.

5. High Accuracy: This device offers a tight voltage threshold accuracy, making it suitable for systems requiring precise voltage monitoring.

6. Low Quiescent Current: The TPS3851 boasts a low quiescent current, which is ideal for battery-operated applications where power consumption is a concern.

7. Packaging: The "EDRBR" in the part number suggests that this specific component is packaged in a WSON (very thin small-outline no leads) format, which is a compact, surface-mount package.

Applications:

Due to its precision monitoring and watchdog capabilities, the TPS3851G33EDRBR is ideal for:

- Systems requiring precise voltage monitoring, such as industrial controls or high-end consumer electronics.

- Microprocessor or microcontroller systems that benefit from an integrated watchdog timer.

- Battery-operated devices where power consumption is a consideration.

- Safety-critical applications where the watchdog can monitor system health.

- Communication equipment and infrastructure.

For comprehensive details, including its electrical specifications, recommended operating conditions, and application notes, it's always best to consult the TPS3851's datasheet directly from Texas Instruments.
