APX803L05-40SA-7 is a type of supervisor that belongs to the category of PMIC (Power Management Integrated Circuits). This kind of supervisor is designed to monitor different voltages in an electronic system and produce a reset signal if any one of those voltages falls out of a specified range. It is used in various types of applications such as automotive, industrial, and consumer electronics.

The power input of the APX803L05-40SA-7 is composed of two pins: V DD and VSS. V DD is connected to a positive voltage supply and VSS to its negative counterpart. Usually, both of these pins are connected to the main power supply of the system. This makes the IC suitable to be used in different kinds of applications, from automotive to industrial and consumer electronics.

The APX803L05-40SA-7 has an integrated brown-out detector and reset timer that serve to detect when the voltage falls below a certain threshold and consequently reset the electronic system to prevent damage due to low-voltage levels. It also has an integrated watchdog timer that periodically checks the progress of the program by producing pulses and resetting the system if it fails to receive a pulse. When the voltage drops below a certain set point, the supervisor will reset the system regardless of the watchdog state.

The IC has one active-high reset output and two active-low reset outputs. These are used to reset the various components in the system. The active-high reset output is mainly used to reset the main processor, while the two active-low ones are used to reset peripheral devices like USB bridges and other logic circuits. The reset is triggered when any one of the input voltages exceeds its active low or active high threshold.

The APX803L05-40SA-7 also has an internal reset signal generator that can generate a variety of reset signals. These signals can be generated as a single pulse, an active-high level, an active-low level, or a combination of the two signals. This makes the IC suitable for a wide range of applications. For instance, in systems with multiple microcontrollers, the reset output of the APX803L05-40SA-7 can be used to synchronize the operation of the different microcontrollers.

The APX803L05-40SA-7 is a versatile and reliable supervisor that can be used in a wide range of applications. It has an active-high and two active-low reset outputs that can be used to reset different parts of a system and has an internal signal generator that can generate different reset signals. As such, it is suitable for automotive, industrial and consumer electronics, as well as a variety of other applications.
