TPS3619-33DGKR Typical application Circuitry

TPS3619-33DGKR is a microprocessor supervisory circuit that offers power-on reset control and watchdog timer features. Essentially, it monitors the supply voltage for microprocessors, microcontrollers, DSPs, and other digital systems and assists in resetting or restarting the system in case of a malfunction or power interruption.

Application Scenarios:

The TPS3619-33DGKR can be used across various electronic platforms including, but not limited to, smart devices, networking equipment, automotive systems, industrial controllers, and computer systems. Its primary role is to ensure the system's proper initialization during power-up and to maintain system integrity during power disturbances.

Key Features:

1. Watchdog Timer with a dedicated output.

2. Manual Reset input.

3. Supply voltage monitoring.

4. wide range of operating temperatures.

5. very little power usage.

Application Example – Industrial Controller System Monitoring:

1. Supply Voltage Input:

- The `VDD` pin of the TPS3619-33DGKR should be connected directly to the system's power supply, allowing the chip to monitor the supply voltage.

2. Resetting the System:

- The `RESET` pin provides a reset signal. This ought to be connected to the controller's or CPU's reset input. In cases where the voltage drops below a predetermined threshold or if the watchdog timer isn't periodically reset, this pin goes active, signaling the controller to reset.

3. Grounding:

- The `GND` pin must be connected to the system's ground to complete the circuit.

4. Watchdog Timer:

- The watchdog timer's output can be found on the 'WDO' pin. It can be connected to an interrupt on the controller, signaling it if the system hasn't been reset within a set timeframe, indicating a possible system hang or malfunction.
- The `WDI` pin is the watchdog timer input. It expects periodic signals from the system. If these signals are absent, it triggers the `WDO`.

5. Manual Reset Mechanism:

- The `MR` pin provides a manual reset option. It can be connected to an external push-button that users can press to manually reset the system.

Design Considerations:

1. Supply Noise: To ensure the TPS3619-33DGKR operates correctly and doesn't false-trigger, use decoupling capacitors close to the VDD pin to filter potential supply noise.

2. Watchdog Timing: Ensure that the system's software or firmware resets the watchdog timer at suitable intervals to avoid unwanted resets.

3. Component Placement: It's advisable to place the TPS3619-33DGKR and associated components in close proximity on the PCB. This minimizes trace lengths and potential interference.

4. External Interference: Given its monitoring nature, keep the TPS3619-33DGKR away from high-frequency or high-power components to prevent undesired interactions.

In summation, the TPS3619-33DGKR is an invaluable component for systems demanding consistent operation and protection against unforeseen power interruptions or malfunctions. Proper integration into a circuit, considering component placement and noise protection, ensures its reliable operation.
