Rohm Semiconductor BD4842G-TR

BD4842G-TR Overview
Rohm Semiconductor is a well-known brand in the electronics industry, and one of their latest offerings is a PMIC - Supervisors chip. This chip falls under the PMIC - Supervisors category, which is responsible for monitoring and controlling the power supply in electronic devices. It is designed to be surface mounted, making it easy to integrate into various circuit boards. The packaging for this chip is in Tape & Reel (TR) format, allowing for efficient storage and transportation. One important factor to consider when using electronic components is their export control classification. In the case of this Rohm Semiconductor chip, it falls under EAR99, which means it does not require a specific export license. This makes it a convenient choice for manufacturers who need to comply with export regulations. In terms of its technical specifications, this PMIC - Supervisors chip has a current rating of 70mA. This means it can handle a maximum current of 70mA without experiencing any issues. The output of this chip is either open drain or open collector, providing flexibility in its use for different applications. It has a pin count of 5, which is a standard number for many electronic components. Another important parameter to consider when selecting a PMIC - Supervisors chip is its maximum output current. In the case of this Rohm Semiconductor chip, it has a maximum output current of 70mA, which is suitable for many low-power applications. Additionally, it has a nominal supply current of 900nA, which is an indication of its low power consumption. One feature that may be of interest to some users is the presence of a watchdog timer. This is a feature that monitors the proper functioning of the chip and can reset it if any issues are detected. However, in the case of this Rohm Semiconductor chip, it does not have a watchdog timer. Finally, this chip has a reference voltage of 4.2V, which is the voltage at which it operates optimally. In conclusion, the Rohm Semiconductor PMIC - Supervisors chip is a reliable and versatile component that offers a range of features and specifications. From its surface mount design to its low power consumption and flexible output options, it is a suitable choice for various electronic applications. Its EAR99 classification also makes it a convenient option for manufacturers who need to comply with export regulations.
