Power Management Integrated Circuits (PMICs) are increasingly relied upon to regulate and optimize voltage and current in order to improve overall system performance, conserve energy, and extend the operating life of any device or system. Supervisors are a subset of PMICs that are specifically designed to monitor the operating conditions of input voltages, to protect the system from unexpected events such as overvoltage, undervoltage, overcurrent, and overtemperature, and when necessary, to shut down the system or reduce power consumption. The ADM810MAKSZ-REEL7 is a supervisor designed to fit the needs of a variety of applications.

The ADM810MAKSZ-REEL7 is a reset circuit with a power good detect, power-on reset delay, and manual and automatic reset. It has an input voltage range of 1.2V to 5.5V, an output drive strength of 8 mA typical, and a 6.5 ms minimum reset pulse width. This supervisor is suited for applications requiring circuit board monitoring, voltage sequencing and protection of microprocessor and other digital circuits, including System on Chip (SoC) components. It uses an autoreset circuit, which holds power-on reset (POR) low for 1.5 seconds after the power voltage is applied, to ensure that the system has time to stabilize before the power-on reset (POR) is released.

The ADM810MAKSZ-REEL7 also features a watchdog timer in order to monitor the performance of a system. The watchdog timer continually checks the state of the system and, when the system experiences difficulties, sends a reset signal to restart it, preventing the system from becoming stuck and improving the reliability of the application. The watchdog timer has an adjustable time interval and output pulse width, allowing the user to customize the features to their particular system.

In order to maintain its specified operation and protect the system, the ADM810MAKSZ-REEL7 has an overtemperature protection (OTP) feature, which detects if the system is operating in an ambient temperature range above the specified operating temperature and shuts down the system to avoid damage. Additionally, the supervisor has overvoltage and undervoltage protection, which detect if the power supply has exceeded or fallen below the specified voltage rating and shuts down the system. These overvoltage and undervoltage detections help to protect the system from short circuits, voltage spikes, and other destructive events.

The ADM810MAKSZ-REEL7 is a highly efficient, integrated supervisor that delivers comprehensive system protection and control for a wide range of applications that require voltage monitoring, sequencing, and protection. With an input voltage range of 1.2 V to 5.5 V, an 8 mA typical output drive strength, a 6.5 ms minimum reset pulse width, overtemperature protection, an autoreset delay, and other features, this supervisor is an ideal solution for applications that require monitoring and protection of system components.
