Frequently Asked Questions
What is the reset threshold voltage of the TPS3823-25DBVT?
The TPS3823-25DBVT has a fixed reset threshold voltage of 2.25V. When the monitored supply voltage drops below this threshold, the device asserts a reset signal to the processor, ensuring controlled system shutdown and restart.
Does the TPS3823-25DBVT include a watchdog timer?
Yes, the TPS3823-25DBVT integrates a watchdog timer (WDT) that monitors processor activity. If the processor fails to toggle the watchdog input within the defined timeout period, the device automatically asserts a reset, preventing system lockup in embedded applications.
What package does the TPS3823-25DBVT come in and what are typical applications?
The TPS3823-25DBVT is available in a 5-pin SOT-23 (TSOP5) package, making it suitable for space-constrained PCB designs. Typical applications include microcontroller supervision in industrial controllers, consumer electronics, handheld instruments, and battery-powered embedded systems requiring reliable reset and watchdog functionality.
Can I use the TPS3823-25DBVT in 3.3V and 5V systems?
Yes, the TPS3823-25DBVT supports a supply voltage range of 0 to 5.8V, making it compatible with both 3.3V and 5V system architectures. Its 2.25V reset threshold is factory-trimmed, requiring no external resistor dividers for standard applications.
