The RT9818G-20GY is a PMIC - Supervisors solution that can bring power stability, versatility and improved system performance to a variety of applications. This PMIC combines a high performance, low quiescent current low dropout (LDO) linear regulator and a two-stage power supervisor IC. The combination of a linear regulator and a supervisor IC makes it an ideal solution for a range of battery-operated applications from smart watches to medical wearables.

The RT9818G-20GY\'s advantage lies in its ability to operate as both linear and switch-mode power supply (SMPS) attributes, or as a combination of both. With its wide input voltage range of 2.25V to 5.5V and ability to support up to 1.8A of continuous current, this PMIC enables manufacturers to develop products with superior power efficiency, low standby current and enhanced system performance.

The RT9818G-20GY\'s integrated LDO regulator includes a low dropout (LDO) linear regulator, a booster and a low quiescent current (LQC) feature. Its integrated two-stage power supervisor IC features a timer switch and an inrush current limiter. This PMIC enables designers to monitor the system power state and receive power fail notifications.

Furthermore, the RT9818G-20GY is designed to exceed the performance requirements of medical and portable applications, providing power optimization and energy efficiency. The PMIC also features a wide range of protection features including over voltage, over current, reverse current protection and thermal protection.

For applications requiring increased safety or reliability, the RT9818G-20GY offers an adjustable delay time, programmable power on reset time (POR) and programmable power off (POFF) time. The PMIC also includes a load short circuit protection, as well as an efficient soft-start design to help ensure a reliable start-up. In addition, the RT9818G-20GY includes an adjustable current limit and a programmable under-voltage lockout (UVLO) function to ensure reliable operations with adjustable triggering thresholds.

The RT9818G-20GY\'s integrated linear and switch mode power supply functions make it an ideal PMIC for applications where robust performance and power optimization are required. Its two-stage power supervisor, integrated LDO, adjustable current limit and programmable timing functions, make it a powerful and versatile solution for a variety of battery-powered devices.
