PMIC (Power Management IC) is one of the most important technologies used in embedded systems to maximize power efficiency and improve system performance. PMICs are generally composed of several components, including supervisors, voltage regulators, power switches, and specialized adapters. A supervisor is an IC used to monitor system reset and power sequence. The ADM8693ARNZ is a low-power, high-performance supervisor IC from ADMtek, suitable for embedded system applications. In this article, we’ll discuss the application field, working principle, and advantages of the ADM8693ARNZ.

Application Field

The ADM8693ARNZ is a low-power, highly reliable supervisory circuit that is mainly intended for embedded system applications such as those found in automotive, industrial, medical, and communication systems. It is especially beneficial in systems that require low-power operation to maximize the battery life. It is compatible with a wide range of power supply voltages, allowing it to be used in a variety of embedded systems. Additionally, the IC supports a wide range of system configurations, making it an ideal supervisor for embedded systems.

Working Principle

The ADM8693ARNZ performs its supervisory function by initially maintaining an output low while the system is in a reset state. When the system is powered up, the IC then monitors the power supply level with its input voltage monitors and releases the system reset when the voltage reaches the specified threshold. At that point, the supervisor can then keep track of power-on reset signals and flag any unexpected reset events. The ADM8693ARNZ also provides support for system-wide power-on reset timeouts, allowing it to quickly respond to system failures and detect soft errors that might otherwise go unnoticed. Additionally, the IC has Backup Power-On Reset (BPROT) support, allowing it to respond to sudden power supply disconnections, ensuring that the system remains in a safe, reset state until power is restored.

Advantages

The ADM8693ARNZ is a highly integrated IC, combining two independent monitoring functions (V core and I/O) in one package. This eliminates the need for having separate components for the two, thereby reducing overall PCB size and power consumption. The ADM8693ARNZ also supports a wide range of power supply voltages, from 3.3 V to 15V, and is capable of operating at temperatures as low as –40°C. Additionally, the integrated circuit is highly reliable, with an MTTF (Mean Time To Failure) of more than 1 million hours. Finally, the device is RoHS compliant and UL/CSA certified, ensuring safety and compliance with regulatory requirements.

The ADM8693ARNZ is a highly reliable, low-power supervisor IC from ADMtek, suitable for embedded systems that require enhanced system reliability and resetting features. Its wide range of features, including monitoring of power supply levels, Backup Power-On Reset support, and operating temperature range, make it an ideal supervisor for automotive, industrial, medical, and communication applications. Furthermore, its high reliability and RoHS/UL/CSA compliance make it a safe and reliable choice for any embedded system.
