Description
Key features of the TPS3824-30DBVR include its precision voltage monitoring with a threshold accuracy of ±2%, a fixed delay time for resetting the microprocessor (200ms typical), and a push-pull RESET output. It operates with a low supply current, making it suitable for battery-powered applications. The device is housed in a small SOT-23-5 package, which allows for space-efficient designs.
The TPS3824-30DBVR is typically used in applications such as embedded systems, consumer electronics, and other digital systems where reliable voltage monitoring is crucial to prevent data corruption or unexpected behavior during power-up, power-down, or brownout conditions.
Equivalent
1. MAX809 - from Maxim Integrated, also provides similar voltage monitoring functionality.
2. STM809 - from STMicroelectronics, a direct equivalent with similar specifications.
3. MIC809 - from Microchip Technology, offering similar monitoring features.
4. ADM809 - from Analog Devices, another alternative with comparable functions.
These alternatives serve similar purposes in monitoring supply voltage levels and generating reset signals for microcontrollers.
Features
1. Voltage Monitoring: It monitors supply voltage levels and ensures they remain within specified limits.
2. Precision Threshold: The device offers a precise 3.0V threshold for voltage monitoring.
3. Manual Reset: It includes a manual reset input for flexibility in system design.
4. Reset Output: The IC provides an active-low reset signal when the monitored voltage falls below the threshold.
5. Reset Delay: Features a programmable reset delay time, allowing system stabilization before releasing reset.
6. Low Power Consumption: Designed for low power applications, it has a low quiescent current.
7. Small Package: Available in a compact SOT-23-5 package, suitable for space-constrained designs.
8. Wide Operating Temperature Range: It operates across a broad temperature range, making it suitable for various environments.
9. High Reliability: Ensures reliable operation of microcontrollers and digital circuits by preventing unexpected resets during voltage drops.
These features make the TPS3824-30DBVR ideal for applications in consumer electronics, industrial controls, and automotive systems.
Pinout
1. Pin 1 (RESET): Active-low reset output. It goes low when the monitored voltage drops below the threshold and remains low for a specified time after the voltage rises above the threshold.
2. Pin 2 (GND): Ground pin for the circuit, serving as the return path for electrical current.
3. Pin 3 (MR): Manual reset input. A low signal on this pin forces a reset, irrespective of the voltage level on VDD.
4. Pin 4 (VDD): Supply voltage pin. It is connected to the monitored voltage source.
5. Pin 5 (WDI): Watchdog input. If this pin is not toggled within a specified time frame, the reset is asserted.
The TPS3824-30DBVR is designed to monitor voltage levels and provide a reset signal to ensure that microcontrollers and other ICs start up and operate correctly.
