Working Principle of X5043S8IZT1

The X5043S8IZT1 is a power-supply system reset supervisor, with integrated circuit protection and a reset signal time-out feature. The X5043S8IZT1 utilizes an innovative reset sequence to ensure system reliability in the presence of power supply noise, brownout conditions, and system reset timing requirements.The X5043S8IZT1 is a monolithic integrated circuit that includes a voltage detection circuit and a reset circuitry. The voltage detection circuit senses the Vcc level and when the supply drops below a user-programmable reset level, the reset signal is generated. The reset signal is used to reset the system, and the voltage detection circuit will remain active until the supply voltage is brought to the reset level.Once the reset signal is generated, the reset circuitry will start a user-programmable reset time-out period. During this period, a reset signal is continuously asserted and the system will remain in reset until the reset time-out period is over. This reset time-out period can be programmed by a user-supplied external capacitor. Once the reset time-out period is over, the reset signal is de-asserted and the system will resume normal operation.The X5043S8IZT1 provides maximum reliability, flexibility, and cost efficiency, and is suitable for numerous applications. The fully-integrated protection devices, low-power and low-cost nature of the PMIC make it a suitable choice for a variety of applications that require a robust power-supply system reset supervisor.
