FAQs
What is TPS3705-33DR?
The TPS3705-33DR is a voltage supervisor IC (integrated circuit) manufactured by Texas Instruments. It is designed to monitor the voltage level of a power supply and provide reset signals to a microcontroller or other system when the voltage falls below a predefined threshold.
How Does TPS3705-33DR Work?
The TPS3705-33DR works by comparing the monitored voltage input with a fixed reference voltage. When the monitored voltage drops below the threshold, the TPS3705-33DR generates a reset signal to ensure the proper operation of the connected microcontroller or system. This helps prevent erratic behavior or data corruption in low-voltage conditions.
How Many Pins does TPS3705-33DR have and What are the Functions of the Pinout Configuration?
The TPS3705-33DR comes in a 6-pin SOT-23 package. The pinout configuration includes:
- VDD: Power supply pin.
- GND: Ground pin.
- MR: Manual reset input pin (active-low).
- RESET: Reset output pin.
- VIT: Voltage input pin.
- TCT: Temperature input pin.
What are the Pros and Cons of TPS3705-33DR?
Pros:
- Voltage Supervision: Monitors voltage levels and ensures system reliability.
- Reset Functionality: Provides a reset signal to prevent system errors during voltage drops.
- Low Power Consumption: Operates with low power consumption for energy-efficient designs.
- Compact Package: Housed in a small SOT-23 package for space-saving applications.
- Temperature Monitoring: Includes a temperature input pin for additional monitoring capabilities.
Cons:
- External Components: May require external components such as capacitors for stability in certain applications.
- Fixed Threshold: The voltage threshold is fixed and may not be adjustable for specific requirements.
- Application Limitation: Designed specifically for voltage monitoring and reset functions, not suitable for other purposes.
Are There Any Equivalents/Alternatives to TPS3705-33DR for Recommendation?
- The MAX8211 from Maxim Integrated is a similar voltage supervisor IC with manual reset functionality.
- Alternatives to the TPS3705-33DR include the ADM6320 from Analog Devices and the MCP809 from Microchip Technology.
