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

Functional Features

• Voltage monitoring: The TPS3820-50QPDBVRQ1 continuously monitors the voltage level and provides a reset signal when it falls below a certain threshold.
• Manual reset: The MR pin allows for manual reset, enabling system control in case of abnormal conditions.
• Power-on reset delay: The device ensures a stable power-on reset delay time of 200ms, allowing sufficient time for the system to stabilize before operation.

Advantages and Disadvantages

Advantages

• Wide supply voltage range enables compatibility with various electronic systems.
• Low quiescent current minimizes power consumption.
• Precision voltage threshold ensures accurate monitoring.
• Small package size facilitates integration into space-constrained designs.
• RoHS compliance promotes environmental friendliness.

Disadvantages

• Limited reset threshold accuracy may not be suitable for applications requiring high precision.
• Lack of additional features such as adjustable reset thresholds or hysteresis.

Working Principles

The TPS3820-50QPDBVRQ1 operates by comparing the monitored voltage level with a preset threshold. When the voltage falls below this threshold, the device generates a reset signal, indicating a power failure or abnormal condition. The power-on reset delay ensures that the reset signal is not triggered immediately upon power-up, allowing the system to stabilize.
