Power management integrated circuits (PMICs) are an important element of every electronic device. PMICs are responsible for monitoring and controlling electrical power flow within a device, as well as providing an efficient, reliable and easy-to-deploy solution for power delivery. Battery management is an essential part of any PMIC, providing the right balance between system performance, lifespan and safety.

The S-8213AAH-M6T1U is a highly-integrated, cost-effective power management integrated circuit (PMIC) with battery management functionality from Renesas. It combines a low quiescent current with low operating voltages, and integrates three general-purpose voltage regulators, four low-dropout (LDO) regulators and four pulse-width-modulation (PWM) converters for a wide range of consumer and industrial systems. The device can be used to provide power to a variety of different devices, including analog and digital sensors, communications nodes, consumer products, display panels, LED drivers, motor control and servos, and mobile I/O solutions.

The S-8213AAH-M6T1U is designed around an ARM Cortex A53 processor core and integrates a battery charging controller and a power management unit (PMU) to provide robust system operation and the highest levels of efficiency. The battery charger has two operation modes, buck mode (charge current up to 1 A) and boost mode (charge current up to 1.5 A). The PMU provides five key functions, including system startup, system health monitoring, power management, voltage monitoring and system shutdown.

The S-8213AAH-M6T1U provides an ideal solution for portable, wireless, and other battery-powered applications, with its safety features such as over-current protection, over-voltage protection, and thermal shutdown. It also includes an on-chip power monitor, which samples and monitors the power supply voltage and temperature, allowing it to dynamically adjust the voltage/current settings for optimum efficiency and protection from over-voltage and over-current conditions.

In addition to its battery management capabilities, the S-8213AAH-M6T1U also provides an array of power control and system management features, including an MPU power-management unit (MPU PMU), a pulse-width modulation (PWM) converter and two low-dropout (LDO) regulators. The MPU PMU provides a comprehensive set of system power control and enhanced power sequencing features that ensure optimal consumption and system performance while extending battery life.

The PWM converter provides highly efficient and precise voltage regulation through four separate output channels. The LDO regulators provide additional voltage regulation with maximum output current setting for each regulator can be scaled to the needs of the device. The S-8213AAH-M6T1U also features a low standby current and typically consumes less than 25 μA when in standby mode.

In summary, the S-8213AAH-M6T1U is an excellent choice for portable and wireless devices, providing an ideal solution for battery management applications. Its highly integrated design offers superior power management capabilities, extended battery life and improved system performance, while its cost-effective package makes it a great value. The advanced system management features, safety features and low standby current combine to offer a first-class power management solution that is suited for a variety of applications.
