PMIC, or Power Management Integrated Circuit (IC), is designed to optimize the performance and power efficiency of a system or system-on-chip. Among its various components, PMICs have supervisors, which are designed to monitor and control power supply conditions in various applications. The X40626V14I-2.7A supervisor is one of the most popular pmic supervisors in the market today. This article will discuss the application field and working principle of the X40626V14I-2.7A supervisor in detail.

The X40626V14I-2.7A is a multi-function supervisor IC designed to provide system power supply and circuit protection for high-end audio and telecommunications applications. It offers the advantages of easy configuration, versatile voltage control, low current consumption and compact, space-saving design. It is suitable for a wide range of power supply topologies, including AC, DC, and high voltage applications, including battery management systems and high-efficiency audio equipment.

The X40626V14I-2.7A is equipped with three programmable hardware alarm pins and one programmable power management I/O pin. It also features an internal momentary-in-time discharge (MID) circuit, which allows the IC to detect and control power supply over and under-voltage conditions. This IC features an adjustable high-voltage analog supervisor, capable of detecting and controlling over-voltage and under-voltage conditions, as well as a programmable brown-out detection circuit for resetting the system.

The X40626V14I-2.7A also has a built-in voltage monitor, using an ADC to monitor the voltage and signal power good (PWRGOOD) conditions. This IC features a programmable power good delay timer, which allows the system to stay in the peak current mode for longer duration. Additionally, the IC has a programmable cycle time, which can be used to control the device\'s switching frequency and time domain performance.

The X40626V14I-2.7A uses a voltage controlled oscillator (VCO) to sense the current output voltage and drives the power (GATE) low if the regulator output voltage is lower than the specified value. The GATE output is open drain, and can be connected to an external pull-up resistor to keep the GATE output high. This IC also has a precision temperature monitoring circuit and an analog comparator for temperature regulation.

Moreover, the X40626V14I-2.7A has a built-in power management supply voltage regulator and a power management I/O circuit. This regulator is designed to provide a constant supply voltage, while the I/O circuit allows external connection to the IC to control its features. The regulator circuit features over-voltage and under-voltage protection, brown-out detection, and thermal shutdown.

Finally, the X40626V14I-2.7A also features a reset output, which can be used to reset the system in the event of an over-voltage or under-voltage condition. This output has an open-drain configuration and can be connected to an external pull-up resistor to maintain the reset output high when powered on. Additionally, the reset output can be connected to other devices in the system, in order to provide synchronized system reset.

In summary, the X40626V14I-2.7A is a multi-function supervisor IC designed to provide system power supply and circuit protection for high-end audio and telecommunications applications. It is equipped with three programmable hardware alarm pins and one programmable power management I/O pin. It also features an internal momentary-in-time discharge (MID) circuit, which allows the IC to detect and control power supply over and under-voltage conditions. This IC has a built-in voltage monitor, a programmable power good delay timer, and a programmable cycle time. Additionally, it has a built-in power management supply voltage regulator and a power management I/O circuit, and a reset output. These features make the X40626V14I-2.7A a versatile and valuable supervisor IC for high-voltage applications.
