Pin Configuration

The TLV6700DDCR is a 5-pin device with the following pinout:

1. GND (Ground)
2. VDD (Supply Voltage)
3. MR (Manual Reset Input)
4. RESET (Active-Low Reset Output)
5. VIT (Voltage Input Threshold)

Functional Features

• Monitors supply voltage and provides a reset signal when it falls below a certain threshold.
• Manual reset input allows for external control of the reset function.
• Active-low reset output can be connected to other devices for system-level reset coordination.
• Wide supply voltage range enables compatibility with various electronic systems.
• Low quiescent current minimizes power consumption.

Advantages and Disadvantages

Advantages: - Precise monitoring of voltage levels ensures reliable operation of electronic systems. - Low power consumption extends battery life in portable devices. - Flexible threshold voltage options cater to different system requirements. - Small SOT-23-5 package allows for space-efficient designs.

Disadvantages: - Limited number of threshold voltage options may not cover all possible system voltage levels. - Active-low reset output may require additional circuitry for compatibility with certain systems.

Working Principles

The TLV6700DDCR operates by comparing the input voltage (VIT) with the selected threshold voltage. When VIT falls below the threshold, the reset output (RESET) is activated, indicating a low-voltage condition. The manual reset input (MR) can be used to override the monitoring function and force the reset output to a high state. The device continuously monitors the voltage and maintains the reset output until the voltage rises above the threshold.

Detailed Application Field Plans

The TLV6700DDCR is commonly used in various applications where reliable voltage monitoring is critical. Some typical application fields include:

1. Power Supply Units (PSUs): Ensures proper operation and protection of power supply circuits.
