What is the MB3793-45DPNF-G-JN-ERE1?The MB3793-45DPNF-G-JN-ERE1 is a power management integrated circuit (PMIC) developed by Fujitsu and manufactured by Matsushita Electric Industrial Co., Ltd (MEI). It is part of Matsushita’s supervisor family, and is in the package type DNP45.This 3"×3" power management IC is a robust and reliable circuit for controlling, regulating, and measuring outputs in a range of applications. It integrates several functional blocks, such as a 5V regulator, a 3V regulator, a 3.3V voltage supervisor, a 3.3V voltage detection circuit, a voltage reference generator, and a temperature sensor. It also has a high-speed control counter (HSC) with an internal oscillator to provide an accurate reference frequency.MB3793-45DPNF-G-JN-ERE1 Application Field and Working PrincipleThe MB3793-45DPNF-G-JN-ERE1 is suitable for controlling and regulating the power supply of digital products. It has applications in a range of industries, including automotive and industrial.The MB3793-45DPNF-G-JN-ERE1 features an integrated voltage regulator, voltage supervisor, and temperature sensor. Its power input is regulated by a 5V regulator, and a 3V regulator is supplied to stabilize the 3.3V output.The voltage supervisor monitors the system voltage and prevents voltage levels from exceeding the set limits. The temperature sensor monitors the temperature of the environment and shuts down the power supply when the temperature reaches a hazardous level. The 3.3V voltage detection circuit is used to monitor the voltage and detect any abnormalities. The voltage reference generator provides an accurate reference frequency which is used to control the counter.The MB3793-45DPNF-G-JN-ERE1 also has built-in safety features, such as an overtemperature protection circuit and an internal oscillator, which monitors the currents and voltages and immediately shuts down the power supply when abnormal conditions occur.The PMIC\'s performance is dependent on the accuracy of its components and the accuracy of the reference frequencies. As such, the MB3793-45DPNF-G-JN-ERE1\'s performance remains consistent, even in harsh environments.Overall, the MB3793-45DPNF-G-JN-ERE1 is a robust and reliable PMIC for controlling, regulating, and measuring outputs in a variety of applications, including automotive and industrial. Thanks to its integrated features, safety features, and accurate reference frequencies, it is a reliable power management solution for digital devices.
