Detailed Pin Configuration

The TPS3823-25DBVR has the following pin configuration: 1. VDD (Supply Voltage) 2. GND (Ground) 3. MR (Manual Reset) 4. RESET (Active-Low Reset Output)

Functional Features

• Voltage Monitoring: Monitors the supply voltage and generates a reset signal when it falls below the specified threshold.
• Manual Reset Input: Allows for manual initiation of the reset function.
• Low Quiescent Current: Consumes minimal current during operation, conserving power.

Advantages and Disadvantages

Advantages
