Detailed Pin Configuration

The TPS389012DSER features the following pin configuration:

1. GND (Ground)
2. VDD (Supply Voltage)
3. MR (Manual Reset)
4. RESET (Reset Output)

Functional Features

• Undervoltage Detection: Monitors the supply voltage and generates a reset signal when it falls below the set threshold.
• Manual Reset Input: Allows for manual triggering of a system reset.
• Power-On Reset Delay: Ensures a stable output during power-up by delaying the reset signal until the supply voltage reaches a specified level.
• Active-Low, Open-Drain Output: Provides compatibility with various microcontrollers and logic circuits.

Advantages and Disadvantages

Advantages

• High accuracy and reliability in voltage monitoring.
• Wide operating temperature range for versatile applications.
• Low power consumption for energy-efficient operation.
• Adjustable threshold voltage settings for flexibility.

Disadvantages

• Limited to monitoring voltage levels and does not provide additional functionality.
• Requires external components for proper operation.

Working Principles

The TPS389012DSER operates by continuously monitoring the supply voltage. When the voltage falls below the set threshold, it generates a reset signal, indicating a power failure or an undervoltage condition. This signal can be used to initiate system resets or trigger specific actions in electronic systems.
