ADM803RAKSZ-REEL7 - Analog Devices Inc.

The ADM803RAKSZ-REEL7 is a high-quality supervisory circuit produced by Analog Devices Inc., designed to monitor power supply voltage levels and system activity in microprocessor systems. This device helps to ensure that the system operates reliably by providing a reset signal to the processor whenever the supply voltage drops below a predetermined threshold, thereby preventing code execution errors during power-up, power-down, or brown-out conditions.

Key Features

• Precision Voltage Monitoring: The ADM803RAKSZ-REEL7 offers precise monitoring of 3.08V power supplies, which is critical for systems that require a stable and consistent voltage for optimal performance.
• Power Supply Glitch Immunity: This device includes built-in glitch immunity to ensure that the microprocessor reset is not triggered by short duration transients on the power supply, enhancing system stability.
• Low Power Consumption: With a low supply current draw of typically 17μA, this supervisory circuit contributes to the overall power efficiency of the system it is integrated into.
• Reset Output Stage: The device features an active low reset output, which remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold level, providing ample time for the system to stabilize.
• Compact Packaging: Supplied in a compact SOT-23 package, the ADM803RAKSZ-REEL7 is suitable for space-constrained applications.

Applications

The ADM803RAKSZ-REEL7 is versatile and can be used in a variety of applications, including:

• Microprocessor & Microcontroller Systems
• Computers & Servers
• Portable/Battery-Powered Equipment
