X5168V14T1

PMIC (Power Management IC) Supervisors, also known as power sequencers, are integrated circuits that are responsible for monitoring and controlling the power supply of electronic systems. As the name suggests, these ICs are usually the "supervisors" of the power supply in a system, making sure that power is delivered safely, securely and in a timely fashion. The X5168V14T1 is an example of such a PMIC and it is used in a variety of applications, from consumer to automotive. In this article, we will look at the application fields and working principle of the X5168V14T1.

Application Fields for the X5168V14T1

The X5168V14T1 is a low-power, single-channel PMIC supervisor. It is designed primarily for use on systems that require a single power supply voltage rail (such as a microcontroller or an FPGA). The device is well-suited to portable applications and consumer electronics due to its low power consumption (of around 100 µA in standby mode). It is also qualified for automotive applications due to its temperature range and its wide input voltage range (3V–28V).

The device is also particularly well-suited to battery management systems (BMS) due to its low power consumption, wide input voltage range and its ability to sense current in two independent channels. With its built-in comparators, the X5168V14T1 can monitor two points on a battery system, allowing it to detect under-voltage or over-voltage event. It can also detect current in both channels, allowing it to detect over-current or low-current events. All of these features make it ideal for battery management applications.

Working Principle of the X5168V14T1

The X5168V14T1 is based on a class of PMICs known as supervisor circuits. In essence, these circuits act as the "gatekeepers" of the power supply in a system, allowing the power to be delivered safely, securely and in a timely fashion. The X5168V14T1 performs this role by controlling the power-on and power-off sequences of the system.

First, the device monitors the incoming voltage rail, detecting if the voltage drops below or rises above certain thresholds. If the voltage drops too low, the device will shut off the power supply in order to prevent damage to the system. If the voltage rises too high, the device will also shut off the power supply, in order to prevent over-voltage conditions. The X5168V14T1 can also detect current sinks in the system, allowing it to detect over-current or low-current events.

As well as controlling the power-on/power-off sequences, the X5168V14T1 is also able to regulate the output voltage and current, ensuring that the system runs at a stable voltage. This can be especially important in battery management applications, where the X5168V14T1 can sense the voltage and current on two independent channels and modify the output voltage accordingly.

Conclusion

The X5168V14T1 is a low-power, single-channel PMIC supervisor that is ideally suited to a variety of applications, from consumer electronics to battery management systems. It is particularly effective at controlling the power-on/power-off sequences of the system, as well as monitoring the incoming and outgoing voltages and currents. This makes the X5168V14T1 an ideal device for a wide range of applications.
