• Quiescent current: 1.5µA (typical)
• Threshold accuracy: ±1.5%
• Power-on reset delay time: 200ms (typical)

Pin Configuration

The TPS3707-33DRG4 has three pins:

1. VDD: Connects to the power supply voltage.
2. GND: Ground reference.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

• Monitors the voltage level and generates a reset signal when it falls below the threshold.
• Provides a stable reset output during power-up and power-down sequences.
• Offers an adjustable delay time for power-on reset.

Advantages

• Low quiescent current consumption helps conserve power in battery-operated devices.
• Wide operating temperature range allows for use in various environments.
• Small package size enables space-saving designs.

Disadvantages

• Limited voltage threshold options, as it is specifically designed for 3.3V applications.
• Lack of built-in hysteresis may lead to potential instability in certain scenarios.

Working Principles

The TPS3707-33DRG4 operates by comparing the input voltage with a fixed threshold. When the voltage falls below the threshold, the device generates a reset signal. This signal remains active until the voltage rises above the threshold again.
