APX803L05-34SA-7

Power management integrated circuits (PMICs) are designed to manage power consumption at different system or component levels. They are responsible for controlling voltage, power sequencing and thermal management for different devices and systems. They are used for various applications such as automotive, mobile, industrial, aerospace and medical markets. Among the various power management solutions, PMIC supervisors are one of the most important components in the overall power management system.

The APX803L05-34SA-7 is a high-precision PMIC supervisor from the APX803L series. It is designed to monitor and manage the power supply system of industrial, automotive and aerospace applications. This supervisor contains three voltage monitoring channels, two reset outputs and an adjustable watchdog timer. It operates within a wide input voltage range of 2.5 V to 5.5 V and provides multiple monitoring, reset and timing functions.

APX803L05-34SA-7 has three monitoring channels, each with its own individual trip point and reset mechanism. The three channels provide voltage monitoring, over-voltage protection and under-voltage protection. It has two active-low, push-pull reset output pins. The two reset output pins are triggered by the active-high reset input signal, the watchdog timer or any of the three monitoring levels. The watchdog timer can be programmable with a time-out period from 1 ms to 1024 ms.

The working principle of the APX803L05-34SA-7 is based on the comparison of a reference voltage to the voltage of the monitored devices and systems. When the monitored device or system is in an abnormal or dangerous condition, the supervisor will detect it and then trigger a reset signal to reset the system. The reset signal can be used to power cycle the system or other corrective measures to restore the system back to its normal operating condition.

The APX803L05-34SA-7 PMIC supervisor is suitable for a wide range of industrial and automotive applications, including power supply systems, oil and gas and automotive applications. It is ideal for applications that require efficient and accurate power supply monitoring, reset and timing functions. With its wide input voltage range, adjustable watchdog timer and multiple monitoring levels, the APX803L05-34SA-7 is a reliable and cost-effective solution for any power supply applications.
