Présentation
Description
Housed in a compact SOT-23 package, the TLV809K33DBZR is ideal for space-constrained applications. It has a low power consumption, typically featuring a supply current in the microamp range, which is essential for battery-operated devices. The active-low reset output becomes active when the monitored voltage dips below the threshold, and it remains active for a specified delay after the voltage recovers, ensuring systems have time to stabilize.
Overall, the TLV809K33DBZR is utilized in various applications, such as computers, embedded systems, and other electronics requiring reliable voltage monitoring and reset functionality.
Equivalent
1. TPS3808G33 – Texas Instruments' own variant with similar functionality.
2. MCP130T-315I/TT – From Microchip, a comparable supervisory circuit.
3. ADM6315-33D3ARTZ – Analog Devices' equivalent with similar voltage monitoring features.
These are used to monitor voltage levels in microcontrollers and ensure proper operation by resetting the system when necessary. Always confirm specifications to ensure compatibility.
Features
1. Precision Monitoring: It monitors a 3.3V voltage rail with high accuracy, ensuring reliable operation within specified voltage limits.
2. Reset Functionality: The device provides a manual reset input and an active-low reset output, essential for initiating a system reset when voltage drops below a preset threshold.
3. Delay Time: It includes an internal fixed delay time of typically 200 ms, ensuring stable reset conditions before releasing the output.
4. Low Supply Current: With a low quiescent current, it is power-efficient, suitable for battery-operated applications.
5. Small Package: The IC comes in a compact SOT-23 package, optimizing board space in design-constrained environments.
6. Temperature Range: It operates effectively over a wide temperature range, typically from -40°C to +125°C, making it suitable for various environmental conditions.
These features make the TLV809K33DBZR ideal for applications requiring precise voltage monitoring and reset control, such as microcontroller and processor-based systems.
Pinout
The TLV809K33DBZR is housed in a SOT-23 package which has a pin count of 3. The functions of the pins are as follows:
1. VDD (Supply Voltage Input): This pin is connected to the supply voltage that needs to be monitored.
2. GND (Ground): This is the common ground pin for the device.
3. RESET (Reset Output): This is an active-low output pin. When the monitored voltage falls below the threshold level, the RESET output is asserted low. It remains low for a specified amount of time after the voltage returns above the threshold.
This 3-pin configuration makes the TLV809K33DBZR suitable for applications requiring simple and reliable voltage monitoring and reset functionalities.
