PMIC - Supervisors

The APX823-29W5G-7 is a supervisor PMIC product from Taiwan-based IC maker Anpec Electronics Corporation. It is a part of their APX series of supervisor products and is designed for industrial, automotive and consumer applications. The APX823-29W5G-7 is an 8-channel device that works on a 2.4V to 5.5V input voltage range. It is capable of delivering up to 2.5A of current and is ideal for applications that require high current and ultra-low system power.

Application Field

The APX823-29W5G-7 supervisor PMIC can be used in a multitude of applications. These include powering up and down systems, controlling power sequencing and regulating voltage levels. It can also be used to protect systems against brown outs, over-voltage and under-voltage transients.

In automotive applications, this supervisor can be used to improve the reliability and durability of the electrical systems in a vehicle. It is also used to ensure safe and consistent operation by regulating operating temperature in sensors and other components. In industrial applications, it can be used to regulate the power supply of a system and protect it against voltage spikes and dips.

In consumer applications, the APX823-29W5G-7 can be used for audio amplifiers, digital cameras, wireless devices and power management for mobile and handheld devices. It can also be used to ensure that the system does not exceed its voltage rating and thereby protect it from damaging as well as inaccurate readings.

Working Principle

The APX823-29W5G-7 supervisor PMIC uses a multiphase gate drive system and a highly accurate voltage monitoring circuit to regulate the power supply of a system. Its multiphase gate drive system allows it to monitor and control the input voltage so that it stays within the specified parameters. On the output side, the APX823-29W5G-7 uses a linear regulator to ensure that the output voltage does not exceed its rated value.

The APX823-29W5G-7 also features an integrated voltage detector that monitors the entire range of input voltages. When the input voltage exceeds the specified upper limit, the device switches off the supply immediately and then switches it back on when the voltage returns to its normal level. The device also features an adjustable over-voltage protection circuit that triggers when the input voltage exceeds the safe operating limit.

The APX823-29W5G-7 supervisor PMIC also offers an integrated soft start function. This function helps the system start up smoothly and prevents the supply voltage from exceeding its maximum voltage rating. The APX823-29W5G-7 also offers fault protection features that ensure safe and reliable operation of the system.

The APX823-29W5G-7 is an ideal choice for a variety of applications. Its multiphase gate drive system, voltage monitoring circuit and adjustable over-voltage protection make it a reliable choice for industrial and automotive applications. In addition, its integrated soft start and fault protection features make it suitable for consumer and handheld devices.
