Partnumber Manufacturer Quantity Availability
ADM707 ADM 69 In Stock

Description and Introduction

Low Cost 礟 Supervisor with 4.65V Threshold Voltage, Power Fail and Watchdog Features and Active Low and High Reset Outputs The ADM707 is a microprocessor supervisory circuit manufactured by Analog Devices. It is designed to monitor the power supply voltage of microprocessor and digital systems. The ADM707 provides three key functions: power-on reset, manual reset, and watchdog timer. 

Key specifications of the ADM707 include:
- **Reset Threshold Voltage**: Typically 4.65V for the ADM707J, 4.40V for the ADM707T, and 4.75V for the ADM707S.
- **Reset Timeout Period**: Typically 200ms.
- **Watchdog Timeout Period**: Typically 1.6 seconds.
- **Operating Voltage Range**: 1.0V to 5.5V.
- **Quiescent Current**: Typically 50µA.
- **Package Options**: Available in 8-pin PDIP, SOIC, and TSSOP packages.

The ADM707 is commonly used in applications requiring reliable power supply monitoring and reset generation, such as in embedded systems, industrial controls, and automotive electronics.

Description and Introduction

Low Cost 礟 Supervisor with 4.65V Threshold Voltage, Power Fail and Watchdog Features and Active Low and High Reset Outputs The ADM707 is a microprocessor supervisory circuit manufactured by Analog Devices. It is designed to monitor the power supply voltage of microprocessor and digital systems. The ADM707 provides three key functions:

1. **Reset Output**: The ADM707 asserts a reset signal when the power supply voltage drops below a specified threshold, ensuring the microprocessor starts in a known state. The reset signal remains active for a minimum period after the power supply returns to the valid operating range.

2. **Power-On Reset**: The device generates a reset pulse upon power-up, ensuring the microprocessor initializes correctly.

3. **Watchdog Timer**: The ADM707 includes a watchdog timer that monitors the activity of the microprocessor. If the microprocessor fails to toggle the watchdog input within a specified time, the ADM707 asserts a reset signal to restart the system.

### Key Specifications:
- **Operating Voltage Range**: Typically 1.0V to 5.5V.
- **Reset Threshold Options**: Available in various fixed thresholds (e.g., 4.65V, 4.40V, 3.08V, 2.93V, etc.) to suit different applications.
- **Reset Timeout Period**: Typically 140 ms (adjustable with external components).
- **Watchdog Timeout Period**: Typically 1.6 seconds (adjustable with external components).
- **Operating Temperature Range**: -40°C to +85°C.
- **Package Options**: Available in 8-pin SOIC and PDIP packages.

The ADM707 is commonly used in applications requiring reliable power supply monitoring and microprocessor reset functionality, such as embedded systems, industrial controls, and automotive electronics.
