• Fixed power-on reset delay time may not be adjustable for specific applications.

Working Principles

The TPS3824-30DBVTG4 operates by continuously monitoring the supply voltage. If the voltage falls below the specified threshold, the reset output is activated, indicating a power failure or an out-of-range condition. The manual reset input allows for a controlled restart of the system. Additionally, the integrated watchdog timer ensures that the system remains responsive by generating a reset signal if it fails to respond within the defined timeout period.

Detailed Application Field Plans

The TPS3824-30DBVTG4 finds applications in various fields, including but not limited to: - Automotive electronics - Industrial control systems - Medical devices - Consumer electronics - Telecommunications equipment
