X4285V8-4.5A

Power management integrated circuits (PMICs) are widely used in a variety of applications and are divided into different product categories, of which supervisory ICs are one. X4285V8-4.5A is a new PMIC - Supervisors introduced by the company recently. The product is widely used in product development, industrial control and power adjustment applications.

The X4285V8-4.5A is a push-pull digital supervisor IC with a low power consumption design. It incorporates a voltage detector, reset circuit and voltage-controlled oscillator into a monolithic device. The device is designed to power up processors and other components connected to it in a reliable, accurate and controllable manner. It can monitor up to 4.5A of current, providing power to numerous components. The device is also equipped with short circuit protection, over temperature protection and over voltage protection.

The main application field of X4285V8-4.5A is power management. It can be used to control the power supply of the processor by monitoring the current of the processor and other components, and control the reset signal of the processor and related components. If the processor or other components are abnormal, it will send the reset signal in time to reset the system, so as to ensure that the processor and related components can work stably and reliably.

The working principle of the X4285V8-4.5A can be divided into two parts: voltage detection and reset signal generation. First, the device accepts an input voltage of 2.25-5.5V. When the input voltage is greater than 2.8V, the voltage detector circuit will output a voltage signal to enable the reset signal generation. Then, the device will generate a reset signal with a reset time of 4 milliseconds or less. During this period, any interrupt requests sent to the processor will be ignored, and the processor will be reset after the reset signal is released.

The X4285V8-4.5A is a versatile supervisor IC that is excellent for power management applications such as processor power supply and reset in industrial control. With advanced design and low power consumption, the device ensures that components can work stably and reliably, avoiding unexpected system resets caused by abnormal voltage or current. With superior features and wide application range, the X4285V8-4.5A is a reliable choice for processor power and reset control.
