FAQs
What is TPS3801L30DCKR?
The TPS3801L30DCKR is a voltage supervisor IC (Integrated Circuit) manufactured by Texas Instruments. It is designed to monitor a power supply voltage and provide reset signals to a system microcontroller or processor to ensure proper operation under all power conditions.
How Does TPS3801L30DCKR Work?
The TPS3801L30DCKR works by continuously monitoring the supply voltage and comparing it to a internally set threshold. If the supply voltage falls below the threshold, the TPS3801L30DCKR asserts a reset signal to initiate a system reset, ensuring proper system operation during power fluctuations or brownout conditions.
How Many Pins does TPS3801L30DCKR have and What are the Functions of the Pinout Configuration?
The TPS3801L30DCKR is housed in a 6-pin SC-70 (Small Outline Transistor) package. The pinout configuration includes:
- VDD: Supply voltage pin.
- GND: Ground pin.
- RST: Reset signal output pin.
- MR: Manual reset input pin.
- MR DIS: Manual reset disable pin.
- CT: Capacitor pin for delay timing adjustment.
What are the Pros and Cons of TPS3801L30DCKR?
Pros:
- Simple Monitoring: Provides straightforward voltage monitoring and reset functionality.
- Low Power Consumption: Operates with low standby current, suitable for power-sensitive applications.
- Small Package: The SC-70 package is compact, saving board space in tight designs.
- Reset Delay Adjustability: The reset delay can be adjusted externally using an external capacitor.
- High Accuracy: Offers precise voltage threshold monitoring for reliable system reset.
Cons:
- Single Voltage Monitoring: Monitors a single supply voltage which may be limiting in some multi-rail systems.
- External Capacitor Required: Requires an external capacitor for configuring reset delay time.
- Limited Features: May not have advanced supervision features present in more complex monitoring ICs.
Are There Any Equivalents/Alternatives to TPS3801L30DCKR for Recommendation?
- The TPS3808 from Texas Instruments is a similar voltage supervisor IC with additional features and multiple voltage monitoring options.
- Alternatives to the TPS3801L30DCKR include the MAX811 from Maxim Integrated and the ADM708 from Analog Devices.
