Visão Geral
Description
Key features of the TPS3824-25DBVR include a precision voltage threshold, low supply current, and a watchdog timer function to monitor system operation. It offers a fixed threshold voltage, typically 2.5V, and has a reset delay time which helps in maintaining system stability during power-up. The device is housed in a small SOT-23 package, making it ideal for space-constrained applications. The TPS3824-25DBVR enhances system reliability by preventing erroneous operations during power-up, brownouts, or power failures.
Equivalent
1. MAX809S: Similar voltage monitoring features and reset threshold.
2. MCP130T-250I/TT: Offers comparable voltage detection and reset functionality.
3. ADM809SARTZ-RL: Provides similar operational characteristics and reset voltage.
These alternatives generally offer equivalent functionality in voltage monitoring and supervisory roles in electronic circuits. Always verify pin compatibility and electrical specifications for your application.
Features
1. Supply Voltage Supervision: It monitors system voltage levels and provides a reset signal to ensure proper system startup and operation.
2. Voltage Threshold: The device is designed to monitor a 2.5V voltage rail.
3. Reset Function: It provides an active-low reset output when the monitored voltage drops below the threshold, ensuring the system is reset when necessary.
4. Delay Time: It features a fixed reset delay time of around 200ms, providing ample time for system stabilization before resuming normal operation.
5. Low Supply Current: The device operates with a low quiescent current, enhancing energy efficiency.
6. Operating Temperature Range: It supports an extended temperature range from -40°C to 85°C, suitable for industrial applications.
7. Package: Available in a compact SOT-23 package, making it ideal for space-constrained applications.
These features make the TPS3824-25DBVR suitable for various applications requiring reliable voltage monitoring and system reset capabilities.
Pinout
Here's a brief overview of the pin functions:
1. VDD (Pin 1): Supply voltage input.
2. GND (Pin 2): Ground reference.
3. ~RESET~ (Pin 3): Active low reset output.
4. MR (Pin 4): Manual reset input, which can be used to trigger a reset externally.
5. WDI (Pin 5): Watchdog input for monitoring system operation.
The TPS3824-25 ensures that when the monitored voltage dips below 2.5V, it will assert a reset signal, preventing potential errors in microcontrollers or other digital systems.
