Overview of TPS3823-25DBVT

The TPS3823-25DBVT is a microprocessor supervisory circuit manufactured by Texas Instruments, designed to monitor system voltages and other parameters critical to the proper functioning of microprocessor and digital systems. This device is particularly suitable for portable and battery-powered applications due to its low power consumption and compact package.

Key Features

• Voltage Monitoring: This supervisory circuit monitors a fixed supply voltage of 2.5V, ensuring that the system voltage remains within acceptable thresholds for reliable operation.
• Power-On Reset Generator: The TPS3823-25DBVT has a built-in power-on reset generator which provides a delayed reset signal upon detection of under-voltage, ensuring the system has stabilized before the processor starts.
• Manual Reset: A manual reset input allows for an external trigger to reset the system, providing additional control for system diagnostics or software-driven resets.
• Watchdog Timer: The integrated watchdog timer helps to detect and recover from system malfunctions. If the watchdog timer is not periodically reset by the system, it will assert a system reset, prompting the system to recover from a possible fault condition.
• Low Power Consumption: Designed for power-sensitive applications, the device consumes very low power, which is crucial for extending battery life in portable devices.
• Temperature Range: The TPS3823-25DBVT operates over a wide temperature range, making it suitable for industrial and automotive applications.
• Small Form Factor: It is available in a compact SOT-23-5 package, which is beneficial for space-constrained applications.
