The RT9818A-26GB is a type of PMIC (Power Management IC) - Supervisors, developed by Richtek. As the market demand for low-profile power management solutions continues to increase, Richtek has created a product solution with the RT9818A-26GB that offers a robust package and exceptional performance.This product solution provides a maximum supply current of up to 26mA, a wide input voltage range of up 1.8V to 5.5V and an output voltage of up to 3.3V. The RT9818A-26GB also has a very low quiescent current of 5μA, making it a great choice for low-power applications. With its wide supply voltage range and low quiescent current, the RT9818A-26GB is perfect for a variety of applications, such as intelligent battery management, IoT and wearables.The RT9818A-26GB is an excellent choice for applications that require dynamic voltage scaling and low power consumption. The dynamic voltage scaling feature can help reduce power consumption when operating under varying loads. For example, when operating under heavy loads, the RT9818A-26GB can reduce the output voltage to prevent overloading the system. In addition, the low quiescent current of 5μA offers a great option for designs requiring very low power consumption.The RT9818A-26GB is designed to provide system protection and margin control. The product offers over voltage and over current protection, brown out detection, reverse supply protection and reverse current protection. The product also includes an adjustable margin control that can be set to a maximum voltage level of up to 5V. This adjustable threshold prevents the system from being overloaded by incoming voltages and drifting into an unsafe state.The RT9818A-26GB is also designed for high reliability, with a constantly updated monitoring system and fault reporting system. The product includes anwatchdog timer, a fault counter, a reset timer and a reset stob. These features help provide reliable operation in even the most extreme environments, protecting against power related issues that can lead to system failure.The RT9818A-26GB is incredibly easy to design in, with a small footprint of only 1.75mm x 1.75mm and an 8-lead package. It can be paired with Richtek’s LLCTIPD3-1 voltage protection devices, allowing for greater system protection in high-voltage applications. Richtek also offers design-in support for the RT9818A-26GB, making it an ideal solution for designers who need a reliable and efficient power solution for their system.In conclusion, the RT9818A-26GB is a great choice for low-power, dynamic voltage scaling applications. Its small size, wide voltage range and low quiescent current make it an ideal choice for battery management, IoT and wearables. Furthermore, its safety features, such as the over voltage and current protections, the reverse supply protection and the adjustable margin control, make theRT9818A-26GB an excellent product solution for reliable system protection.
