• Active-low reset output
• Small package size

Package

The MAX805REPA+ is available in a small 8-pin PDIP package.

Essence

The essence of MAX805REPA+ lies in its ability to monitor the supply voltage and generate a reset signal when the voltage falls below a certain threshold.

Packaging/Quantity

The MAX805REPA+ is typically packaged in reels or tubes, with a quantity of 250 units per reel/tube.

Specifications

• Supply Voltage Range: 1.0V to 5.5V
• Reset Threshold Voltage: Adjustable from 1.2V to VCC-0.6V
• Reset Timeout Period: Fixed at 140ms (min)
• Quiescent Current: 7µA (typ)
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

The MAX805REPA+ has the following pin configuration:

```

---

| | --| RESET |-- --| GND |-- --| MR |-- --| VCC |-- --| RESET_OUT |-- --| THRESHOLD |-- --| GND |-- |___________| ```

Functional Features

• Voltage monitoring: The MAX805REPA+ continuously monitors the supply voltage.
• Reset generation: When the supply voltage drops below the set threshold, the MAX805REPA+ generates a reset signal.
• Adjustable threshold: The reset threshold voltage can be adjusted to suit specific application requirements.
• Active-low reset output: The reset output is active low, indicating a system reset condition.
• Low supply current: The MAX805REPA+ operates with low quiescent current, minimizing power consumption.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Adjustable reset threshold provides flexibility in different applications.
• Small package size enables space-saving designs.
• Low supply current minimizes power consumption.

Disadvantages

• Fixed reset timeout period may not be suitable for all applications.
• Limited pin configuration options may restrict certain circuit designs.

Working Principles

The MAX805REPA+ works by comparing the supply voltage with the set threshold voltage. When the supply voltage drops below the threshold, the internal circuitry generates a reset signal. This signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX805REPA+ finds applications in various electronic devices, including: 1. Microcontrollers and microprocessors 2. Embedded systems 3. Power management circuits 4. Battery-powered devices 5. Industrial control systems

Detailed and Complete Alternative Models

1. MAX809REUR+: Similar to MAX805REPA+, but with a push-pull reset output.
2. MAX811TEUS-T: Voltage supervisor with adjustable reset threshold and watchdog timer.
3. MAX803TEXR+: Ultra-low-power voltage supervisor with manual reset input.

These alternative models offer similar functionality and can be considered as substitutes for the MAX805REPA+ in different applications.
