The X4003S8Z is a member of a family of PMIC - Supervisors. PMIC, or power management integrated circuits, are designed to be used as controllers for generating and managing power, enabling multiple subsystems to efficiently interface with control power and system power sources. Supervisors are one common type, and they regulate and control the power supply within a range of applications.

The X4003S8Z is a highly efficient regulator and supervisor. It is specifically designed to provide reliable, single-ended or differential power supply deliver to current-limited microprocessors or microcontrollers. It optimizes system performance with low waiting and restart delay currents and extremely low quiescent current. It is fully protected with short- to open-circuit protection, over-voltage protection, and current limit protection.

The X4003S8Z is designed for use in applications where circuit stability and energy efficiency are important features. It is suitable for various applications such as medical, industrial, consumer products, smart wearables and hand-held devices, automotive systems, and many others. Its efficiency and power-saving features ensure that it is able to provide reliable power supply when used in low-power and battery-powered applications.

The X4003S8Z is composed of a voltage adjustment and a supervisor circuit. The voltage adjustment circuit is composed of a bandgap reference section, an error amplifier, and an output buffer circuit. The voltage adjustment circuit provides a constant output voltage with a low single-ended output impedance, low current noise, and excellent thermal characteristics. It is also able to provide quick transient response, providing better load regulation characteristics.

The supervisor circuit is used to monitor and protect the system by watching the voltage conditions. It is composed of an analog monitor, a trip point logic comparator, a reset latch, an oscillator, and a reset output circuit. The monitor is used to compare the voltage demand to an insulated reference voltage. It triggers a trip point logic comparator which sets the reset latching circuit when the predetermined trip point level is reached. This trip point can be adjusted by an external resistor.

The X4003S8Z has a reset output circuit which provides an active-low reset signal automatically with the reset latch. The reset output is activated with a 0.1µs short reset pulse. The reset output can be controlled either manually or automatically by an external control-signal. The oscillator duty cycle can be adjusted according to rate frequency of 0.1 Hz to 1kHz.

The X4003S8Z is a versatile and efficient supervisor which is designed for various applications. It has a low quiescent current and its output is capable of delivering up to 1A of current. It has a high transient response with fast voltage regulation and excellent current limiting protection. It can be used to provide over-voltage protection, short-to-open circuit protection, and current limit protection, making it suitable for a wide variety of applications.
