Functional Features

• Voltage monitoring: The TPS3850G33QDRCRQ1 continuously monitors the voltage level and provides a reset signal when it falls below or rises above the set threshold.
• Manual reset: The MR pin allows for manual reset, enabling system control in case of abnormal conditions.
• Watchdog timer: It includes a watchdog timer that generates a reset signal if the system fails to toggle a specific signal within the specified timeout period.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for versatile applications.
• Low quiescent current minimizes power consumption.
• Adjustable threshold voltage provides flexibility in voltage monitoring.
• Small package size saves board space.

Disadvantages

• Limited number of pins may restrict the integration of additional features.
