Infineon‘s portfolio of brushed DC motor drivers includes a variety of architectures including advanced gate drivers, single and multi halfbridges, as well as motor systems ICs with integrated power supply and communication interfaces as LIN and CAN transceivers.
Infineon’s brushed DC motor drivers offer high performance at an optimized system cost for various automotive applications, including but not limited to: power seat modules, power closure systems, HVAC controle modules, decentralized mirror modules, T-Case.
Infineon offers a broad portfolio of brushed DC motor driver ICs. Depending on the required output current and preferred integration level the offer ranges from single- or multiple half bridges and full bridges including the MOSFETs or multiple MOSFET drivers within one device. The latest innovative product family of the Motor System ICs is combining the halfbridge driver with supply and communication interface as CAN FD or/and LIN.
The new Multi MOSFET Driver IC family consists of 8-fold or 4-fold halfbridge driver ICs in one device in a VQFN-48 package. All devices are pin and software compatible and so the family concept is simplifying the design-in process but maximizing the flexibility in design. Infineon’s patented Adaptive MOSFET Control concept is reducing cost and eliminating efforts of end-of-line MOSFET calibration by an internal feedback loop between Infineon’s Driver IC and the MOSFETs. Target applications as comfort motor drive systems in seat or power lift gate ECUs are optimized with PWM capability up to 20 kHz or multiple load control out of a body control module (BMC) as centralized door lock.
Infineon’s innovative product family of Motor System ICs is combining the advance gate driver using the patented Adaptive MOSFET Control concept with a low-dropout voltage regulator of up to 250mA, CAN FD (5 Mbit/s) and LIN transceiver as well as well as high-side switches (7Ω typ.), wake inputs and supervision features. All devices are in VQFN-48 package and therefore in combination with the Multi MOSFET Driver ICs the scalability is maximized, the design in effort is reduced by using the same gate driver concept and making both product families a perfect fit for various automotive DC motor applications requiring flexibility for different platform designs for seat adjustment, power lift gate or sunroof module.
The products combining driver stage and MOSFETS for automotive brushed DC motor applications cover low current motors of around 1 A used in mirror adjustment or HVAC flap control systems, with the Multi Half bridge Drivers. For applications up to 7 A the Full Bridge Drivers offer a broad portfolio of devices suitable for powertrain application and many more. Currents up to 55 A and the advanced protection and diagnostic of the single halfbridge drivers of the NovalithIC family are a perfect fit for security relevant applications, like electronic parking brake, active suspension control, fuel pumps.
