The ADM8693ARUZ is part of Analog Devices Inc.’s (ADI’s) power management integrated circuit (PMIC) and supervisor portfolio. The ADM8693ARUZ provides power management solution for a wide range of consumer medical and industrial applications. It is a versatile PMIC that combines a wide range of reliable, secure and cost-effective power management features in a tiny package.

The ADM8693ARUZ is a 4-channel PMIC designed to deliver versatile, high-efficiency system power management features. It comprises two voltage regulators, two low dropout (LDO) linear regulators, two Supervisors and a watchdog circuit. The two voltage regulators feature independent power paths to provide general-purpose power management for microcontrollers, memory and other digital circuits. The two LDOs provide power supplies that are necessary for analog circuits to deliver low-ripple and low-noise operation. The ADM8693ARUZ also features two Supervisors that can be independently programmed to detect power supply problems while monitoring VDDs and system temperatures. Finally, the device includes a watchdog timer that can be set independently at any interval from milliseconds to seconds to periodically reset the system when an unexpected condition arises.

Power management is critical for medical and industrial applications for safety and security reasons. The ADM8693ARUZ is ideal for applications that require power management features such as current limiting, power-on reset, thermal control and overvoltage protection. This PMIC is designed to meet the stringent safety requirements of medical, industrial and avionics applications.

The ADM8693ARUZ integrates two voltage regulators, two LDOs, two Supervisors and a watchdog timer, making it an ideal choice for applications requiring multiple power management functions. It offers an integrated power-on reset circuit that can detect low voltage conditions and provide a reset signal for a microcontroller, an adjustable current limit circuit to protect the system from inrush currents, an overvoltage protection circuit and an adjustable temperature sensor for thermal control. The ADM8693ARUZ also includes an event counter and an alarm signal that can be used to monitor system events or to alert the system of an overvoltage or temperature fault.

In addition to providing multiple power management features, the ADM8693ARUZ also integrates several features that can be used to extend battery life in applications such as handheld devices. The device offers adjustable switching frequency to reduce power consumption, and it can be used in conjunction with a timer interrupt circuit to provide power savings when the system is in idle mode. The ADM8693ARUZ also features a power gating control that allows the device to be powered down when not in use, further reducing system power consumption.

The ADM8693ARUZ is a cost-effective and versatile PMIC that offers multiple features to provide reliable power management for medical and industrial applications. Its integrated voltage, current and temperature protection and extended battery life features make it an ideal choice for applications that require reliable and secure power management.
