The PT7A7534WEX is a supervisor from the PMIC (Power Management IC) family that is designed for the embedded control systems. This supervisor offers the most advanced features for a multi-function voltage monitoring system, and it is classified as a supervisory IC. Such a product is capable of providing overvoltage protection, microprocessor reset and timer functions.

The application field of the PT7A7534WEX is mainly in the field of embedded control systems. This supervisor is ideally suited for automotive, avionic and wireless communication applications. It is also useful in consumer electronics such as embedded audio amplification control systems and providing protection against short-circuiting. The motor control and protection in industrial applications are supported by this supervisor as well.

The working principle of the supervisor is based on the voltage surveillance. It has two high voltage monitoring circuits and two voltage-setting circuits for different power supply voltages. The supervisor also has two open-drain outputs that can be configured as reset outputs or open-drain outputs. The reset output is used to signal the power-on reset of the system and can be also used for enabling and disabling the reset circuit. The open-drain output can be used for initiating the reset function when the voltage is above or below the programmed threshold.

The supervisor offers precise on-the-fly voltage monitoring with an accuracy of 1%. It has a precise voltage detection delay of 10us, so it is suitable for use in high speed switching power supplies. The supervisor also offers adjustable power down delay, which is suitable for controlling the wake-up sequence in a system. It also has a built-in power-saving circuit which is capable of reducing the total power dissipation.

The PT7A7534WEX is a highly reliable supervisor device which is suitable for use in the embedded control systems. It offers the most advanced features for a multi-function voltage monitoring system and it is used in various applications such as automotive, avionic and industrial control systems. The operating principle of this supervisor is based on the voltage surveillance and it also provides precise on-the-fly voltage monitoring with an accuracy of 1%.
