PMIC, or Power Management IC, is a broad term encompassing a wide range of integrated circuits that are used to manage the power of a circuit or system. Supervisors are a type of PMIC which are generally used to protect integrated circuits from fault conditions. Electrical over-voltage and over-current faults can be damaging to ICs and therefore supervisors are used to ensure that the ICs are not damaged by such conditions.

The MAX6388XS20D1-T is a supervisor from Maxim Integrated which is used to monitor the over-voltage and over-current conditions of a circuit.

Application Field

One of the most useful applications for the MAX6388XS20D1-T is in the protection of battery-powered consumer electronics products. This supervisor monitors the voltage and current of the battery circuit to ensure that the battery is not over-charged or over-discharged. It can also be used to monitor the over-voltage and over-current conditions of other power rails in the system such as the main power rail. This supervisor is most commonly used in consumer electronics such as mobile phones and tablets, as well as wearables and home appliances.

In addition to consumer electronics applications, the MAX6388XS20D1-T can also be used in automotive applications such as solving over-voltage and over-current conditions caused by the alternator. This supervisor is also found in industrial, medical and aerospace applications.

Working Principle

The MAX6388XS20D1-T consists of two independent channels which each monitor the voltage or current of a power rail. Each channel has two input options for either voltage or current and one output which can be connected to an interrupt or reset line on the IC.

The supervisor is pre-programmed with fault thresholds for both the over-voltage and over-current conditions. When the voltage or current of a monitored power rail exceeds its respective threshold, the supervisor will output a high signal to the IC\'s interrupt or reset line. This signal informs the IC that it should protect itself from possible damage or destruction due to over-voltage or over-current conditions.

The MAX6388XS20D1-T also includes various protection functions such as reverse power-supply protection, low-input voltage detection and over-temperature protection. These functions all ensure that the system is not damaged due to external conditions or faults.

Conclusion

The MAX6388XS20D1-T is a supervisor from Maxim Integrated that can be used to protect circuits and systems from fault conditions such as voltage and current overshoot. It is suitable for use in a variety of applications such as consumer electronics, automotive, industrial, medical, and aerospace applications. The supervisor includes various protection functions such as reverse power-supply protection, low-input voltage detection, and over-temperature protection to ensure that the system is not damaged due to external conditions or faults.
