Modern electronic systems are complicated structures, consisting of many separate elements, each of which has its own voltage and current requirements. In order to ensure that all components receive the right amount of power, efficient power management systems must be implemented. PMICs, or Power Management Integrated Circuits, are used to manage the power flow in complex electronic designs. These devices are designed to regulate, protect, and convert multiple voltage rails in order to guarantee safe and efficient power delivery.

One example of a PMIC is the KA75450MTF, a device designed for high precision applications. KA75450MTF is a Supervisory Circuit (Supervisor)—a power management device that monitors voltage levels and safeguards against overcurrent and overvoltage conditions. The KA75450MTF has several integrated features, including: an adjustable reset threshold, power-on reset, watchdog timer, and an open collector output.

The KA75450MTF’s primary application field is within PC and PC servers/workstations, aerospace systems, medical equipment, communications, and automotive systems. This PMIC is ideal for these applications for a few reasons. Firstly, it offers superior accuracy and high performance, thanks to its precise voltage monitoring accuracy of +-1% tolerance. Secondly, it is designed for flexibility and reliability, with a wide reset voltage setting range of 4.65V to 5.5V. Thirdly, the device is designed with high-temperature operation in mind, providing excellent reliability even in the most extreme temperature conditions. Furthermore, it also offers both buffered and unbuffered reset outputs, as well as optional reset pulse stretching to guarantee multiple reset pulse widths.

The working principle of the KA75450MTF revolves around its ability to monitor voltage levels and provide an indication of when they exceed acceptable limits. The device has two internal comparators, one which monitors the supply voltage, and the other which monitors a voltage set by the user. When the supply voltage exceeds the upper reset threshold, the device’s reset output is activated, which then triggers a reset signal to the target circuitry. Conversely, when the supply voltage falls below the lower reset threshold, the output will deactivate, and the reset signal is no longer sent. The watchdog timer can also be used to generate periodic reset pulses when it is enabled by external logic.

The KA75450MTF is an excellent example of PMIC’s designed for precision applications. It is a Supervisory Circuit designed to monitor various voltage levels, protect against current and voltage spikes, and provide reset signals when necessary. It is ideal for a variety of applications, such as PC servers/workstations, medical equipment, aerospace systems, communications, and automotive systems. Its wide range of features make it an extremely reliable and versatile choice for power management systems.
