Detailed Pin Configuration

The TPS3124G15DBVR has the following pin configuration:

1. GND: Ground connection
2. VDD: Power supply input
3. MR: Manual reset input
4. RESET: Reset output

Functional Features

Voltage Monitoring

The TPS3124G15DBVR continuously monitors the voltage level at the VDD pin. If the voltage drops below the programmed threshold, the device triggers a reset signal.

Manual Reset

The MR pin allows for manual reset control. When pulled low, it forces the device to generate a reset signal regardless of the voltage level.

Power-On Reset Delay

The TPS3124G15DBVR includes a power-on reset delay circuit that ensures stable operation during power-up. This feature prevents false resets caused by voltage fluctuations during system startup.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring
• Low power consumption
• Small package size
• Wide operating temperature range

Disadvantages

• Limited threshold voltage options
• Lack of adjustable hysteresis

Working Principles

The TPS3124G15DBVR operates based on a voltage comparator circuit. It compares the voltage at the VDD pin with the programmed threshold voltage. If the voltage falls below the threshold, the device generates a reset signal. The manual reset input and power-on reset delay circuit enhance its functionality.
