Detailed Pin Configuration

The MAX803SEXR/GG8 is a three-pin device with the following pin configuration:

1. VCC: Supply Voltage Input
2. GND: Ground
3. RESET: Reset Output

Functional Features

• Monitors the supply voltage and asserts the reset output when the voltage drops below the threshold.
• Adjustable threshold voltage options allow flexibility in system design.
• Low quiescent current ensures minimal power consumption.
• Reset timeout period prevents false resets during power-up or voltage fluctuations.

Advantages and Disadvantages

Advantages: - Small package size enables space-saving designs. - Wide supply voltage range allows compatibility with various systems. - Adjustable threshold voltage provides customization options. - Low quiescent current minimizes power consumption.

Disadvantages: - Lack of built-in hysteresis may result in oscillations near the threshold voltage. - Limited reset timeout period may not be suitable for certain applications requiring longer delays.

Working Principles

The MAX803SEXR/GG8 operates by continuously monitoring the supply voltage. When the voltage drops below the programmed threshold, the reset output is asserted. The reset remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX803SEXR/GG8 finds applications in various fields, including: - Microcontrollers and microprocessors - Embedded systems - Battery-powered devices - Industrial automation - Consumer electronics

Detailed and Complete Alternative Models

Some alternative models to the MAX803SEXR/GG8 include: - MAX809: Similar voltage detector IC with fixed threshold options. - MAX811: Voltage detector IC with manual reset input. - MAX631: Voltage detector IC with watchdog timer functionality.
