Detailed Pin Configuration

The TPS3837J25DBVTG4 has the following pin configuration:

```

---

| | --| VDD | --| GND | --| RESET | --| MR | --| VOUT | |___________| ```

• VDD: Power supply input
• GND: Ground reference
• RESET: Active-low reset output
• MR: Manual reset input
• VOUT: Power supply monitor output

Functional Features

1. Voltage Monitoring: The TPS3837J25DBVTG4 continuously monitors the voltage level and provides a reset signal when it falls below the threshold.
2. Reset Output: The active-low RESET pin indicates when the voltage is below the threshold, allowing for system reset or other actions.
3. Manual Reset: The MR pin allows for manual reset control, overriding the automatic monitoring function.
4. Fixed Timeout Delay: The reset signal remains active for a fixed 200ms delay after the voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring with ±1% accuracy
• Low quiescent current consumption, minimizing power usage
• Wide operating temperature range for versatile applications
• Small package size suitable for space-constrained designs
• RoHS compliant, ensuring environmental friendliness

Disadvantages

• Fixed timeout delay may not be adjustable for specific application requirements
• Limited reset threshold options (2.5V in this case)

Working Principles

The TPS3837J25DBVTG4 operates by comparing the monitored voltage with a fixed threshold of 2.5V. When the voltage drops below this threshold, the reset output becomes active, indicating a fault condition. The reset signal remains active for a fixed 200ms delay after the voltage rises above the threshold. The device also includes a manual reset input for additional control.

Detailed Application Field Plans

The TPS3837J25DBVTG4 finds applications in various fields, including:

1. Battery-Powered Devices: It ensures proper voltage monitoring in portable devices, preventing damage due to low battery levels.
2. Industrial Control Systems: The voltage supervisor helps maintain stable operation in industrial control systems, protecting sensitive components from voltage fluctuations.
3. Automotive Electronics: It plays a crucial role in automotive electronics, ensuring reliable operation and preventing system failures.
4. Medical Equipment: The TPS3837J25DBVTG4 is used in medical devices to monitor voltage levels and trigger appropriate actions when necessary.
