Introducing the APX393SG-13 from Diodes Incorporated

The APX393SG-13 is a robust, high-performance microprocessor supervisory circuit, engineered by the reputable semiconductor manufacturer, Diodes Incorporated. This compact and efficient device is designed to maintain system integrity by monitoring the power supply voltage in digital systems and microprocessor-based applications. Its primary function is to assert a reset signal whenever the supply voltage drops below a predetermined threshold, ensuring that the system initializes in a known state.

Encased in a space-saving SOT-23 package, the APX393SG-13 is an ideal choice for applications where board space is at a premium. The device features a low supply current, which makes it suitable for use in portable and battery-operated equipment. With its wide operating voltage range, the APX393SG-13 can cater to a diverse array of applications, from consumer electronics to industrial control systems.

One of the key attributes of the APX393SG-13 is its precision voltage monitoring capability. The device offers a factory-trimmed threshold voltage that ensures accurate sensing of under-voltage conditions. This precision is critical in applications that require consistent and reliable operation, even under fluctuating power conditions.

The APX393SG-13 also boasts an active-low reset output, which remains asserted for a minimum of 140ms after the supply voltage has risen above the reset threshold level. This delay provides the connected microprocessor with adequate time to stabilize and set up its operations upon power-up or during a brown-out condition.

Another significant advantage of this supervisory circuit is its immunity to short-duration voltage glitches on the power supply, thanks to its built-in glitch immunity. This feature helps to prevent false resets, which can be detrimental to the performance and reliability of the system it is protecting.

In summary, the APX393SG-13 from Diodes Incorporated is a highly reliable and essential component for any system that demands vigilant monitoring of its power supply. Its combination of low power consumption, precision monitoring, and compact form factor makes it an excellent choice for designers looking to enhance system reliability without sacrificing performance or space.
