Description

The TPS3823-25DBVR is a supervisory circuit manufactured by Texas Instruments, designed to monitor system power in microprocessor and microcontroller applications. It ensures reliable system operation by providing a reset signal whenever the supply voltage drops below a preset threshold or during power-up/power-down cycles. The device is designed with precision under-voltage detection at 2.5V and features a fixed time delay for reset signal release, typically 200ms after the supply voltage has stabilized above the threshold.
Packaged in a small SOT-23 configuration, the TPS3823-25DBVR is suitable for space-constrained applications. It operates over a wide temperature range, making it versatile for various environments. The device's low power consumption is ideal for battery-operated systems. Additionally, it provides a push-pull, active-low reset output, ensuring compatibility with most digital logic. This device is particularly useful in applications where microprocessor stability is critical, such as in automotive systems, consumer electronics, and industrial equipment.

Features

The TPS3823-25DBVR is a voltage supervisor IC produced by Texas Instruments, designed to monitor supply voltage levels in microcontroller and digital systems. Key features include:
1. Voltage Supervision: It monitors the supply voltage and asserts a reset signal whenever the voltage falls below a preset threshold of 2.5V.
2. Low Supply Current: Typical supply current is approximately 15 µA, making it suitable for battery-powered applications.
3. Precision Monitoring: Offers a precision voltage threshold with an accuracy of ±1.5%.
4. Manual Reset Capability: Provides an input for manual reset, allowing users to initiate a reset independently from the monitored supply voltage.
5. Active-Low Reset Output: The reset output is active-low, and it remains asserted until the voltage returns to an acceptable level and the reset timeout period has elapsed.
6. Reset Delay Time: Configurable reset delay time to ensure stability before the system is restarted.
7. Package: Available in a compact SOT-23-5 package, suitable for space-constrained applications.
These features make the TPS3823-25DBVR ideal for ensuring system reliability in microcontroller and digital systems by preventing erratic operations during power supply variations.
