• Precision: It provides accurate voltage monitoring with low voltage thresholds.
• Low power consumption: The device operates with low quiescent current, making it suitable for battery-powered applications.
• Wide operating range: It can operate within a wide voltage range, typically from 1.6V to 5.5V.
• Temperature range: ADM708SARZ can function reliably in a temperature range of -40°C to +85°C.

Package

ADM708SARZ is available in a small outline integrated circuit (SOIC) package.

Essence

The essence of ADM708SARZ lies in its ability to monitor the power supply voltage and generate a reset signal when necessary, ensuring proper system operation.

Packaging/Quantity

This product is typically sold in reels containing a specific quantity of units, such as 2500 pieces per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: Adjustable (typically 4.63V)
• Reset Timeout Period: Adjustable (typically 140ms)
• Quiescent Current: 20µA (typical)
• Power-On Reset Delay: 100ms (typical)

Detailed Pin Configuration

ADM708SARZ has the following pin configuration:

1. VCC: Power supply input
2. GND: Ground reference
3. RESET: Output reset signal
4. MR: Manual reset input
5. VTH: Voltage threshold adjust
6. CT: Capacitor connection for reset timeout adjustment

Functional Features

1. Voltage Monitoring: ADM708SARZ continuously monitors the power supply voltage.
2. Reset Generation: When the voltage falls below the threshold, it generates a reset signal to initiate system reset.
3. Adjustable Threshold: The voltage threshold can be adjusted using the VTH pin to suit specific application requirements.
4. Manual Reset: The MR pin allows for manual reset initiation when pulled low.
5. Reset Timeout: The CT pin enables adjustment of the reset timeout period.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring
• Low power consumption
• Wide operating range
• Adjustable threshold and timeout period
• Manual reset capability

Disadvantages

• Limited availability in certain package options
• May require additional external components for specific applications

Working Principles

ADM708SARZ operates by comparing the power supply voltage with a preset threshold. When the voltage drops below this threshold, the internal circuitry triggers a reset signal. The reset signal remains active until the voltage rises above the threshold or a timeout period elapses.

Detailed Application Field Plans

ADM708SARZ finds applications in various fields, including but not limited to: - Microcontrollers and microprocessors - Embedded systems - Industrial automation - Automotive electronics - Power management systems
