MOTIX™ single half-bridge ICs for BDC motors

MOTIX™ single half-bridge ICs from Infineon

MOTIX™ single half-bridge IC family of smart, integrated motor driver ICs support high currents and are designed for use in automotive and industrial applications. A MOTIX™ single half-bridge is a smart low-ohmic, protected half-bridge in a single package. It can be combined with an additional half-bridge to create an H-bridge or 3-phase bridge as well. The MOTIX™ single half-bridge IC family has the capability to switch high frequency PWM while providing overcurrent, overvoltage and overtemperature protection. It offers cost-optimized solutions for protected high-current PWM motor drives with very low board-space consumption scaled to your needs.

Benefits and highlights of single half-bridge ICs from Infineon

• Space saving (fully integrated in single small-footprint device: minimized external components).
• High quality device showing strong reliability after many years of experience and vast number of pieces sold.
• Thanks to protection and diagnosis features as well as its half-bridge partitioning the MOTIX™ single half-bridge ICs enable highly reliable solutions.
• MOTIX™ single half-bridge ICs are easy to use and allow direct inputs from the microcontroller and minimize layout and manufacturing efforts.

Infineon's portfolio of MOTIX™ single half-bridge ICs

Infineon offers low- and high-current single half-bridges designed for use in automotive and industrial applications. It can be combined with additional MOTIX™ single half-bridge ICs to create an H-bridge or 3-phase bridge as well. Interfacing with a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature, undervoltage, overcurrent and short circuit.

Single half-bridge ICs for high-current PWM motor drive applications

The many protection and diagnosis features of the MOTIX™ single half-bridge ICs devices make them ideal for security relevant applications, like electronic parking brake, active suspension control or fuel pumps. Due to its durability and ease-of-use these devices are also ideal for electronic seatbelt pretensioners, T-Case, HVAC control module, and many more.

MOTIX™ BTN99x0LV ISO 26262-ready status

The ISO 26262-ready marking designates QM products that can – with additional analysis and evaluation support from Infineon – be integrated into a customer’s ISO 26262 compliant, safety-related application, even though they have not been designed or developed according to the ISO 26262 standards. 

Infineon provides a Safety Application Note (SAN) for ISO 26262-ready devices that are designed to aid the customer through the evaluation process. This important document also contains valuable information to support the integration of the component into the customer’s safety-related system. Although it remains the customer’s responsibility to evaluate whether the product details are suitable and sufficient to support the integration within an ISO 26262 compliant system, the information provided in the SAN will significantly reduce the required effort.

The PRO-SIL™ ISO 26262-ready marking designates QM products that can – with additional analysis and evaluation support from Infineon – be integrated into a customer’s ISO 26262 compliant, safety-related application, even though they have not been designed or developed according to the ISO 26262 standards.

The requirements specified in ISO 26262:2018 clauses 8-13 and 8-14 may be applied by customers to ensure that the device’s functional behavior is adequate to meet the allocated safety requirements for the application level. In general, PRO-SIL™ ISO 26262-ready parts support ISO 26262:2018 clause 8-13 class II hardware evaluation.

Infineon provides a Safety Application Note (SAN) for PRO-SIL™ ISO 26262-ready devices that is designed to aid the customer through the evaluation process. This important document also contains valuable information to support the integration of the component into the customer’s safety-related system. Although it remains the customer’s responsibility to evaluate whether the product details are suitable and sufficient to support the integration within an ISO 26262 compliant system, the information provided in the SAN will significantly reduce the required effort.
