Power Management Integrated Circuits (PMICs) are devices that enable the integration of various power management functions into one chip. PMICs allow designers to reduce board space and cost while adding flexibility to the design. PMICs are used in a wide range of applications, including audio power amplifiers, cellular, base station power supplies, FPGA/ASIC/DSP power management, networking/telecommunications, and many other applications.Supervisors are a type of PMIC, and they provide continuous monitoring of system voltage levels. The BU4242F-TR is a Supervisors from ROHM Semiconductor that offers the necessary functions to ensure system reliability. This device combines a voltage supervisor, reset circuit, and watchdog timer, providing system reliability and control.The BU4242F-TR is designed for use in automotive applications, and it does not require external components, making it a cost-effective solution for managing power in vehicles. This device is voltage-monitoring IC with a watchdog timer and active reset output options. The voltage monitoring is capable of detecting input voltage levels from 0.5V up to 6.5V, and the reset outputs are active-high, active-low, and open-drain type.The BU4242F-TR can detect system voltage levels, reset the CPU when the voltage levels exceed or fall below predefined thresholds, and issue a reset signal when there is a timeout period. It also has a watchdog timer, which monitors the system at predefined intervals to make sure the system is operating properly. If the system fails to meet the system requirements within the predefined watchdog timer period, the BU4242F-TR will issue a reset signal. The watchdog timer period can be programmed using a simple external timing circuit, allowing designers to customize the device for different applications. The BU4242F-TR has a wide operating temperature range of -40°C to +125°C, making it suitable for automotive applications. In addition, the device is ESD protected, making it robust and reliable for operation in harsh environments. The device is also RoHS compliant and available in a variety of package options.The BU4242F-TR is an ideal solution for applications requiring reliable power monitoring and reset functions, such as automotive power systems. Its combination of features make it an economical and reliable solution for system reliability and control. Its wide operating temperature range and ESD protection make it suitable for use in automotive environments, while its simple external timing circuit allows for customization. It is also RoHS compliant and available in a variety of package options, making it the perfect choice for automotive applications.
