会社ブログについて Brand-New, Genuine ADI ADM6713—A Microprocessor Monitoring Circuit for Industrial Control, Automotive Electronics, and Portable Devices

Mingjiada Electronics now offers brand-new, genuine ADI (Analog Devices) ADM6713 microprocessor monitoring circuits (reset generators) in stock, Housed in a 4-pin SC70 ultra-compact package, this device features ultra-low power consumption of 12 μA, a minimum reset timeout period of 140 ms, and six selectable reset threshold voltage options ranging from 2.32 V to 4.63 V, making it a core component for power monitoring and reset management in applications such as microprocessor systems, computers, controllers, smart instruments, and automotive electronics.

ADM6713 Product Overview

The ADM6713 is a reset generator circuit introduced by ADI, part of the microprocessor monitoring circuit (voltage monitor) series, and is a counterpart to the ADM6711. Both are suitable for microprocessor-based systems, providing a reset signal during power-up, power-down, and when the supply voltage drops below a preset threshold. In addition, both devices feature a debounced manual reset input that can be triggered by an external switch or logic signal, facilitating system debugging and error handling.

The main difference between the ADM6713 and the ADM6711 lies in the output stage configuration: the ADM6711 features a push-pull output that requires no additional external components, while the ADM6713 features an open-drain output that requires an external pull-up resistor; if necessary, this resistor can be connected to a voltage higher than VCC, providing flexible interface level options for system design.

The ADM6713 offers six different reset threshold options covering a range from 2.32 V to 4.63 V, making it suitable for monitoring 2.5 V, 3 V, 3.3 V, and 5 V supply voltages. When VCC rises above the threshold, the device generates a reset timeout of at least 140 ms, providing sufficient stabilization time for the supply voltage before the microprocessor starts up.

The device features a precision reference voltage source, is highly reliable, and is immune to fast, negative transients on VCC. Low current consumption and a space-saving 4-pin SC70 package make it ideal for low-power portable applications.

ADM6713 Key Features

1. Ultra-low-power design

The ADM6713 has a quiescent current of only 12 μA, a figure that leads the industry among similar microprocessor-based monitoring circuits. For battery-powered portable devices and industrial control systems requiring continuous, long-term operation, this ultra-low-power characteristic significantly extends battery life and reduces overall system power consumption.

2. Six Reset Threshold Levels Covering Mainstream Supply Voltages

The device offers six reset threshold options ranging from 2.32 V to 4.63 V, precisely matching the monitoring requirements of 2.5 V, 3 V, 3.3 V, and 5 V power supplies. Engineers can select the appropriate model based on the actual supply voltage used in the system, eliminating the need for an external resistor divider network, which simplifies circuit design and improves threshold accuracy.

3. Open-Drain Output for Flexible Interface Levels

The ADM6713 employs an open-drain output structure, allowing external pull-up resistors to be connected to voltages higher than VCC, facilitating interfacing with microprocessors or controllers operating at different logic levels. This feature is particularly useful in multi-voltage-domain systems, enabling flexible level conversion of reset signals.

4. Debounced Manual Reset Input

The device features a debounced manual reset input pin that can trigger a system reset via an external button or logic signal, providing a convenient hardware reset channel for device debugging, fault recovery, and user interaction.

5. Precision Reference and Immunity to Interference

The ADM6713 incorporates a precision reference voltage source with power supply interference suppression capabilities, making it immune to fast, negative transients on VCC. It ensures the accuracy and reliability of the reset signal even in industrial environments with significant power supply fluctuations or noise interference.

6. Full Temperature Range Specifications

The device is fully specified across the extended industrial temperature range of −40°C to +125°C, making it suitable for applications with stringent environmental requirements, such as automotive electronics, industrial control, and outdoor equipment.

Application Areas

Thanks to its ultra-low power consumption, precise voltage monitoring, and flexible output configuration, the ADM6713 is widely used in the following scenarios:

Microprocessor Systems: Provides power-on reset, power-down reset, and undervoltage reset signals for processors such as MCUs, DSPs, and MPUs, ensuring that the processor begins operation only after the power supply has stabilized, thereby preventing program runaway or data corruption

Computers and Embedded Systems: Used for power monitoring and reset management on platforms such as motherboards, industrial PCs, and single-board computers

Controllers: Power sequencing management for industrial control equipment such as PLCs, motion controllers, and motor drive controllers

Smart Instruments: Power monitoring for precision instruments such as digital multimeters, oscilloscopes, and data loggers

Automotive Systems: Reset management for automotive electronic modules such as in-vehicle ECUs, instrument clusters, and infotainment systems

Portable Devices: Thanks to its ultra-low power consumption of 12 μA, it is suitable for battery-powered handheld terminals and wearable devices
