• Reset Timeout Period Options: 140ms, 560ms, 1120ms, 2240ms
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

The MAX809TEUR+T has three pins:

1. GND: Ground pin
2. RESET: Active-low reset output pin
3. MR: Manual reset input pin

Functional Features

• Low quiescent current consumption
• Accurate voltage monitoring
• Adjustable reset threshold voltage and timeout period
• Manual reset capability for system initialization
• Push-pull or open-drain reset output options

Advantages and Disadvantages

Advantages: - Low power consumption - Wide operating voltage range - Adjustable reset threshold and timeout period - Small package size

Disadvantages: - Limited number of available reset threshold voltage options - No built-in hysteresis for voltage monitoring

Working Principles

The MAX809TEUR+T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the programmed threshold, the reset output is activated, indicating a power failure or low voltage condition. The reset output remains active until the voltage rises above the threshold or a manual reset signal is applied.
