Power management integrated circuit (PMIC) is a sub-category of integrated circuits that specializes in power conditioning and energy management for multiple , powered components in a circuit. PMICs are designed to effectively manage these components by monitoring and controlling their power supply. The KA75250ZBU is an example of PMIC and falls in the category of Supervisors. It plays a role in providing overheat protection and reset in power supply ICs or other ICs.This particular PMIC integrates over temperature (OT) detection circuits, delay circuit and Power-On Reset (POR) circuit with monitor circuits in its core. The monitor circuits monitor the operation status of the system, whereas the OT detection circuit provides overheat protection by detecting the temperature of the surrounding environment or, in some cases, the temperature of the device.The KA75250ZBU integrates an adjustable OT reset signal that detects the temperature of the embedded system, and it provides one output signal after the signal falls below a certain temperature. The delay circuit output signal of the KA75250ZBU provides a delay time to wait for the system to enter into a safe temperature range before releasing the reset signal.In short, the KA75250ZBU provides overheat protection and reset signal monitoring for power supply ICs and other ICs. It can be used in a wide range of applications, including power control and supply circuit in automotive systems, industrial system control, embedded systems and other applications that require efficient power management and energy management. The main feature of this PMIC lies in its integration of both over temperature reset signal and delay circuit. The adjustable over temperature reset signal detects the temperature of the embedded system and provides one output signal after the signal falls below a certain temperature. Furthermore, the delay circuit provides a delay time before the reset signal is released, ensuring the system enters into a safe temperature range. Additionally, the KA75250ZBU includes a built-in reset monitoring control circuit, which monitors the reset signal input and output. This ensures that the output reset signal is synchronized with the input signal, providing a stable and reliable reset signal. The KA75250ZBU contains a watchdog circuit, which monitors the system for unexpected reset signals and provides a warning when these signals are detected. The watchdog circuit also provides a reset signal when the reset signal is detected, which can be used to shut down the system.Another important feature of the KA75250ZBU is its low power consumption. The PMIC only consumes approximately 400 µA of current when an active reset signal is provided. This helps to reduce the system\'s power consumption, translating into longer operational time, and making it ideal for energy-efficient and cost-effective applications.Overall, the KA75250ZBU is an ideal choice for applications that require efficient power management and energy management. This PMIC integrates over temperature detection circuits, delay circuit, and power-on reset circuit with monitor circuits, providing overheat protection and reset signal monitoring. Furthermore, the low power consumption of the KA75250ZBU helps to reduce the system\'s power consumption, providing better operational efficiencies.
