FAQs
What is APX803S-31SA-7?
The APX803S-31SA-7 is a voltage detector with reset function manufactured by Diodes Incorporated. It is commonly used to monitor the power supply voltage of microcontrollers, ASICs, and other electronic devices to ensure a safe reset when the voltage falls below a predefined level.
How Does APX803S-31SA-7 Work?
The APX803S-31SA-7 works by continuously monitoring the power supply voltage. When the voltage drops below a specific threshold, the device triggers a reset signal, which can be used to restart or initialize the connected microcontroller or system. This ensures proper operation and prevents erratic behavior or data corruption due to low voltage conditions.
How Many Pins does APX803S-31SA-7 have and What are the Functions of the Pinout Configuration?
The APX803S-31SA-7 is housed in a SOT-23-3 package. The pinout configuration includes:
- VDD: Power supply pin.
- GND: Ground pin.
- RESET: Reset output pin.
What are the Pros and Cons of APX803S-31SA-7?
Pros:
- Low Power Consumption: Consumes very low power, suitable for battery-operated devices.
- Small Package: The compact SOT-23-3 package is space-efficient, ideal for space-constrained designs.
- Reset Function: Provides a reliable reset signal when the voltage falls below a specific level, ensuring system stability.
Cons:
- Fixed Threshold: The voltage threshold for triggering the reset is fixed and may not be adjustable.
- Single Function: Designed specifically for voltage monitoring and reset, limiting its versatility for other applications.
Are There Any Equivalents/Alternatives to APX803S-31SA-7 for Recommendation?
- The XC6501 series from Torex Semiconductor offers similar voltage detector and reset functions in a variety of package options.
- Alternatives to the APX803S-31SA-7 include the MAX803 and MAX809 series from Maxim Integrated, which provide similar voltage monitoring and reset capabilities.
