```

---

| | --| RESET | --| GND | --| MR | --| VDD | --| N.C. | |___________| ```

Functional Features

• Monitors the supply voltage and asserts a reset signal when it falls below the specified threshold.
• Provides an adjustable power-on reset delay time to ensure stable system operation during power-up.
• Offers an open-drain output that can be connected to other devices for system-level control.

Advantages and Disadvantages

Advantages

• Low quiescent current consumption helps in conserving power.
• Wide operating temperature range allows for use in various environmental conditions.
• Adjustable power-on reset delay time provides flexibility in system design.

Disadvantages

• Limited to a specific voltage threshold of 5.0V, which may not be suitable for all applications.
• The SOT-23-6 package may not be compatible with certain space-constrained designs.

Working Principles

The TPS3828-50QDBVRQ1 operates by continuously monitoring the supply voltage. When the voltage falls below the specified threshold (5.0V), it asserts a reset signal. The power-on reset delay time can be adjusted to ensure that the reset signal is held for a sufficient duration during power-up. The open-drain output allows for easy integration with other devices in the system.
