X5169S8Z-4.5A

The X5169S8Z-4.5A is a low quiescent current voltage supervisor IC with built-in source driver and reset controller. This IC is designed for use in Portable consumer, Industrial, IoT and Automotive applications to enable a controlled power-on sequence during system power-up, power sequencing and sequencing for domain control. It has two main operating blocks, a reset generator block and a source driver block.

The reset generator block is used to generate a reset signal that can be used to assert the microprocessor\'s reset line. The reset signal is generated when either the voltage or the current level exceeds predefined thresholds or if any other event defined in the user-configurable programming modes is detected. This method of reset generation avoids triggering an undesired reset to the system during power up, even in cases where the supply voltage is changing slowly or has slow rising or falling edges which can easily affect the accuracy of the system.

The source driver block of the X5169S8Z-4.5A is designed for heavy load applications. This block can drive high currents into the supply rail, so the system keeps powering on and the microprocessor does not reset. This block also contains a slew-rate control circuitry which helps in controlling the rate of change of the supply voltage during power up, power down, and during sleep and wake-up sequences. This feature avoids any erratic behaviour of the system by preventing sudden transitions in the system voltage.

The X5169S8Z-4.5A also offers adjustable reset and power-on-delay timer circuitry that can be programmed to provide 50ms or higher delay to allow the system and supply voltage to settle before powering on the microprocessor, thus improving the reliability of the system. The IC also comes with an adjustable push-pull output which can drive up to 80mA and can be used to provide a supply voltage indication signal.

The X5169S8Z-4.5A packs a wide variety of features and offers a compact solution for application in different types of systems. This IC can be used in various applications such as Industrial/Automotive, Low/Mid/High Power Application, DC/DC Converters, PoE System and Mechanical/Electrical Safety devices, where reliable power up and reset sequence is required.

In summary, the X5169S8Z-4.5A is a low quiescent current, high-performance PMIC device that can be used in a wide range of applications whether for powering, sequencing or for domain control purposes. With its wide range of features and its compact size, the X5169S8Z-4.5A is an ideal choice for use in any design that requires reliable power-on sequence and reset management.
