PMIC - Supervisors refer to a range of ICs designed to detect and correct power supply issues that can cause problems with integrated circuits. APX803S00-26SR-7 is a supervisor IC from Diodes Inc., a global leader in the analog and mixed-signal semiconductor market.

The APX803S00-26SR-7 is a low-dropout (LDO) voltage supervisor, intended for protection and monitoring in digital systems. It is a single-channel voltage supervisor with internal power-on reset (POR) and power-under reset (PUR) circuitry. The supervisor is designed to provide stable voltage or power supply regulation even as the input voltage drops to a critical level. This makes the supervisor an ideal choice for applications where proper voltage regulation is essential.

The APX803S00-26SR-7 features an adjustable reset voltage threshold, allowing for accurate voltage level detection and protection. This voltage supervisor is designed to have a wide supply voltage range of 1.7V to 6.0V, and requires a minimum operating current of just 4µA at 5V. With an under-voltage lockout of 0.6V, the supervisor ensures consistent operation and prevents over-current conditions. It also incorporates a 1.2V low supply voltage lockout, ensuring proper functionality of digital components.

The APX803S00-26SR-7 has a number of unique features, including an active low POR signal and an open-drain PUR output. The POR signal can activate an external reset circuit while the PUR output will pull low when the input voltage is below a certain threshold. In addition, the supervisor has built-in hysteresis and an adjustable reset time delay to prevent spurious triggering of the reset signal.

The APX803S00-26SR-7 has a wide range of applications, including automotive, industrial, and consumer electronics. In automotive systems, this voltage supervisor is used to monitor and regulate power supply levels in electronic control units. In industrial systems, it is used to monitor and protect process control, safety, and instrumentation loops. Additionally, the APX803S00-26SR-7 can be used in consumer electronic applications, such as personal computers, tablets, and other portable devices.

The APX803S00-26SR-7 works by monitoring the input voltage supply and triggering a reset signal if the voltage falls below a predetermined threshold. When the voltage is restored to normal levels, the reset signal will automatically be turned off. This ensures consistent and reliable power regulation, preventing components from damage caused by sudden power surges. The supervisor also protects against data corruption due to unexpected power losses.

The APX803S00-26SR-7 is an excellent choice for applications with high power reliability and efficient protection against power supply fluctuations. With its ability to accurately monitor the input voltage and provide a reset signal when needed, the supervisor is able to protect digital components from unexpected power failures. Furthermore, its small size, low power consumption and wide supply voltage range make it well-suited for cost-sensitive applications.
