The MP62170EK-1-LF-P is a power management integrated circuit (PMIC), specifically classified as a Power Distribution Switch, Load Driver. As the name suggests power distribution switches are ICs that are used to allow the power that is generated charging and to be switched, shared and distributed over different circuits, and Load Drivers are ICs able to control voltage and current that flows between two different stages. This particular PMIC is made by Monolithic Power Systems and is intended for use within systems that have a maximum voltage of 32V and a load current of 10A, such as motor and solenoid control, reverse battery protection, and LED drive applications.

The MP62170EK-1-LF-P has a total of eight external input/output pins that interface with the main application circuit. These inputs/outputs can either be connected to an external logic device, such as a microcontroller, or connected directly to the power source depending on the application. In either case, it is important for the environment in which the PMIC is used to understand the complete system operation as any variation in power, ambient temperature, transient noise, or component type can introduce failure in the system.

The MP62170EK-1-LF-P is a single channel power distribution switch, load driver IC and it is designed to provide up to 10A of current to power systems and applications. This IC features an integrated operational amplifier (op-amp) that enables precise current and voltage regulation, as well as over voltage and over current protection circuitry to ensure safe operation of the system. The device also includes a thermal shutdown module, which will automatically shut down operation of the PMIC if the system overheats in order to protect against catastrophic failure.

The MP62170EK-1-LF-P device is driven turn on and turn off times are based on the resistance of the external sense resistor and the external bypass capacitor. The device utilizes a simple on/off power switch, to provide independent control of the loads enabled by the PMIC. The device’s internal op-amp provides precise current regulation and easily adapts to changes in load conditions. In order to maintain a smooth transition between loads, the device also has built in auto tuning circuitry that stablize the current level during dynamic load transitions.

The MP62170EK-1-LF-P is an ideal PMIC for a variety of applications, such as motor and solenoid control, reverse battery protection and LED drive. This is made possible due to the device’s wide operating voltage range of 8V to 32V and its built-in over voltage and over current protection circuitry. When designing a system utilizing this PMIC, it is important to note that all external components must be rated for use at the maximum operating temperature specified by the device. The device can either be mated to existing circuitry using a 26-pin SOIC package, or mated to a PCB using an 8-pin DIP package.

The MP62170EK-1-LF-P is a highly integrated, single channel power distribution switch, load driver IC. This device is well suited for a variety of applications that require precise current and voltage regulation and protection against over voltage and over current scenarios.
