Power management integrated circuit (PMIC) supervisors are integrated circuits (ICs) used in a variety of electronic configurations to provide voltage and programming supervisory functions. PMIC supervisors are designed to provide low-power, cost-effective solutions for applications requiring additional voltages, system reset, and assurance that the power supply is good and that the system is operational. This article will discuss the application field and working principle of ADM1815-R22AKSZ-R7, a PMIC supervisor.
Application Field
The ADM1815-R22AKSZ-R7 is used in power management systems requiring increased voltage ranges and multiple system reset functions. It is specifically designed for use in automotive, industrial, portable, and telecommunications applications, as well as other applications that demand high integration of voltage supervisory functions. It can be used in DC/DC converters, voltage regulator modules (VRMs), battery chargers, and other custom power management systems that require a combination of system resets, power-on reset (POR) signals, and protection features.
The device features a selectable operating voltage range from 8.0V to 20V and provides additional POR signals that can be used to detect out of range or over voltage events. It incorporates an adjustable watchdog timer that can be programmed to trigger a reset when the system fails to detect a certain event within the programmed interval. The device also provides a power-loss detection circuit that can be programmed to issue a reset signal on your system when power is lost. This ensures that your system is restarted properly even if the power is lost.
Working Principle
The ADM1815-R22AKSZ-R7 is based on an advanced power-management subsystem, which includes a power supply, voltage regulator, and supervisory circuitry. The power supply provides the primary voltage for the rest of the system and is protected by an under voltage lockout circuit that prevents operation if the voltage goes below the programmed value. The voltage regulator then adjusts the voltage level of the system depending on the specific application requirements. The supervisor circuit then monitors the voltage level and provides protection against voltage spikes, over voltages, and under voltages. The supervisor also includes a programmable watchdog timer that triggers a reset if a certain event is not detected within a certain interval. The device includes a reset output that ensures that your system is reset after the power has been lost. This ensures that your system is always running properly.
The ADM1815-R22AKSZ-R7 is designed to provide an efficient means of regulator voltage control and reset protection. Its efficient power-management subsystem ensures that your system is always running properly, and its integrated features provide a reliable and cost-effective solution for your application needs. Its wide operating voltage range allows it to be used in a variety of applications that require a combination of system reset and voltage regulator functions. With its versatility and compact form factor, the ADM1815-R22AKSZ-R7 is an ideal choice for power management systems.
