PMIC - Motor Drivers, Controllers – IRMCK171TY

PMIC stands for power management integrated circuit. It is a central component of any system responsible for controlling the power utilized, monitored and dispersed via the system. IRMCK171TY is one such PMIC designed for Motor Drivers and Controllers.

IRMCK171TY is based on the Infineon OptiMOS™3 Power Block Technology which enables high efficiency switching with minimum losses. It integrates a power stage, driver and controller which eliminates the need for complex discrete components. This makes it ideal for applications that need high performance and low power consumption such as power tools, lawn mowers and vacuum cleaners. The IRMCK171TY allows for smooth and synchronous control of the motor and has current sensing and protection features which further enhance safety.

The IRMCK171TY works as a dual brushed DC motor driver and controller. Its main features include:

• Integrated current sensing for dynamic and static current control
• Integrated charge pump for the switching unit
• An autonomous motor control by an integrated timer and comparators
• Integrated overvoltage protection and undervoltage protection for the motor supply
• Integrated protection for the MOSFETs used in the power stage including overvoltage protection and reverse current protection
• Motor enable/disable functionality
• A serial bus interface compliant with the I2C protocol

The IRMCK171TY utilizes Infineon’s OptiMOS™3 technology and can be operated with a supply voltage of up to 40V. It has been designed with an ambient temperature range of -40°C to +85°C. The IRMCK171TY is also suitable for use in automotive applications with higher temperature range and stringent EMC requirements.

The IRMCK171TY is a powerful and highly integrated PMIC for motor drivers and controllers. It eliminates the need for complex discrete components by integrating a power stage, driver and controller. It offers high efficiency switching with minimum losses, current sensing and protection features which further enhance safety. It is suitable for applications that need high performance and low power consumption and can be used with a supply voltage of up to 40V.
