Introduction

X40030S14IZ-B is a power management IC (PMIC) supervisor with various functionalities, including input/output monitoring and protection, reset signaling, sequencing and supervision. It is mainly used in embedded systems, automotive and consumer electronics, as well as Industrial applications. Its main functions are the protection of devices from overvoltage, undervoltage lockout, input current monitoring and current-limiting protection.

Application Field

X40030S14IZ-B is a very useful PMIC supervisor for applications that require input/output monitoring and protection, or for applications that require reset signaling, sequencing and power supervision. The device is well-suited for embedded systems and consumer electronics, such as computer and communication systems, TVs, CD players, DVD players, and other audio and video equipment. It is also effective in automotive applications and industrial applications, including alarm systems and motor load control. In addition, this device can be used in solar panel systems, as well as in various other applications.

Working Principle

X40030S14IZ-B employs two sets of independent supply voltage monitors, two programmable over voltage protection (OVP) circuits, an under voltage lockout (UVLO) circuit and an adjustable current-limited power switch. When an input voltage is applied to the device, the OVP and the UVLO circuits check the regularity of the supplied voltage. If the voltage is normal, the regulator starts to work and generates a specific output voltage, which is adjustable by connecting a voltage divider to the dedicated VCC pin. The current-limited power switch, also connected to this pin, will provide a certain current-limited output voltage.In addition, X40030S14IZ-B has a dedicated reset output pin connected to a circuit that monitors the input supply and output of the device, to detect if the output voltage is over a certain threshold voltage. If the output voltage is over this threshold, the reset pin will be activated and pull down the supply voltage. Furthermore, the system can be regulated by a built-in delay timer, which automatically triggers after a certain time interval.The X40030S14IZ-B device comes with two types of reset control. The RC mode is used to ensure that the supply voltage is always held at a specific level. As a result, the system power can be reset by the integrated reset control circuit. The man-guarded mode, on the other hand, uses the RV pin (reset output) to activate the reset signal when the threshold voltage for the reset output is reached.

Conclusion

X40030S14IZ-B is a power management IC supervisor with a wide range of applications that make it suitable for a variety of applications, from embedded systems and consumer electronics to automotive applications and industrial applications. The device offers a comprehensive set of features and capabilities, including input/output monitoring, over voltage protection, under voltage lockout, and adjustable current-limited power switch. In addition, this device has a built-in reset control circuit and delay timer to provide a comprehensive reset solution.
