Power management integrated circuits (PMICs) are the backbone of nearly every electronic design. PMICs can provide a range of power management functions such as voltage regulation, standby power and fault management. They are designed to help engineer reduce power losses and meet power delivery requirements.

Supervisors are a major category of PMICs. Supervisors provide power engineers with the assurance that their design will start up correctly, respond gracefully to power faults and transition from standby to active without fail. Supervisors are often used to trigger a reset event if the desired power sequencing steps are not followed. Supervisors can provide the power sequencing necessary for responding to power faults in mission-critical systems.

APX803S05-40SA-7 is a sophisticated supervisor for some special application field. It is widely used in industrial, automotive, healthcare and other embedded systems. The APX803S05-40SA-7 is an ultra-low-power, two-voltage supervisor with two independent power supplies. It provides low-voltage and permanent disruption features to enhance system reliability and safety in various applications.

The APX803S05-40SA-7 is designed to monitor two independent power supplies. When monitoring a power supply that uses linear voltage regulation, it can detect output voltage variation as low as 0.1%. When monitoring a power supply that uses low-dropout regulators, it can detect output voltage variation as low as 0.25%. The APX803S05-40SA-7 features selectable reset thresholds, reset assertion and de-assertion time delays and a power-on reset timer.

The APX803S05-40SA-7 offers a variety of system control options. It can be used to generate a reset signal, a sequencing signal or an enable signal for a Digital-to-Analog Converter (DAC) or other active power device. It also provides monitoring of power-on reset conditions and separate reset outputs for primary and secondary power supplies.

The APX803S05-40SA-7 can be connected to either a single power supply, or to two separate power supplies, allowing the device to respond to either power supply under-voltage or over-voltage conditions. When the device detects an under-voltage or over-voltage condition, it will assert the active-low reset signal and keep it asserted until the power supply returns to its normal operating range.

The APX803S05-40SA-7 features an extensive list of features that make it well-suited for many applications. It has a low-power consumption, allowing it to be used in low-power applications, and it supports 2.7V to 5.5V supply voltage operation. In addition, it has an integrated temperature sensor and a programmable event counter for system logging.

In summary, the APX803S05-40SA-7 is a versatile supervisor that is ideal for a wide range of applications. It can monitor two independent power supplies and detect output voltage variation as low as 0.1%. It features low-power consumption and supports various modes of operation. It also offers a variety of system control options, such as generating a reset signal and monitoring power-on reset conditions. As a result, APX803S05-40SA-7 can provide engineers with assurance that their design will start up correctly and respond gracefully to power faults.
