The ICL7665AEPA is a power management integrated circuit (PMIC - Supervisor) from Intersil Corporation. It is a versatile device that provides power sequencing, sequencing control, over voltage, under voltage, over current, and temperature protection for circuit board components. The ICL7665AEPA is typically used in computer, communication, and other industrial applications.

The basic function of the ICL7665AEPA is to provide a comprehensive power sequencing solution to protect valuable circuits. The device is typically used to monitor the power supply voltage and current in the system, and its threshold is programmable by the user. It then controls up to 15 channels of power supply sequencing and protection. The device provides over voltage protection (OVP) and over current protection (OCP) for the entire power system.

In operation, the ICL7665AEPA monitors the VDD and VIN supplies, and can react to faults in two ways: by latching a fault and requiring a reset, or by automatically switching off the power supply. The ICL7665AEPA also provides power sequences like Power on Reset (POR), Power on Reset Delayed (PRD), Watchdog Reset (WDR), and Watchdog Reset Delayed (WRD). It has up to 25 precision comparators with adjustable reference, hysteresis, and output type for process monitoring.

The ICL7665AEPA delivers accurate voltage, temperature, and current monitoring and control. It also features high precision A/D conversion with 12-bit resolution, over-temperature protection, and over-current protection. The device integrates several power management functions, making it ideal for computer, communication, and other industrial applications.

The ICL7665AEPA has various applications in modern electronic systems such as Wide Area Network (WAN) routers, Shared Internet Radio (SIR) systems, Power Grid Management Systems (PGMS), High Definition Multimedia Interface (HDMI) systems, and other control and monitoring systems. In these applications, the device monitors the system parameters, such as voltage, temperature, current, and system time. It can detect faults in the system, and can react accordingly. With its wide range of features, the ICL7665AEPA is a reliable and efficient PMIC that is ideal for any application.
