    About

    Compact solution for high-current PWM motor drives. 

    MOTIX™ BTNxxxx 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.

    Highlights

    • 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.

    The products are easy to use, allow direct microcontroller input, and minimize layout and manufacturing effort.

    What are the key features of Infineon's multi half-bridge ICs?

    MOTIX™ TLE9166EQ for door control offers a versatile solution for door control modules, featuring 6 half-bridges with inrush current management, 25 kHz PWM, configurable slew rate, 6 high-side switches (one configurable as high-side or LDO), 1 LDO for off-board sensors, and 2 gate drivers for electrochromic mirrors and heaters. The device is optimized for use with MOTIX™ TLE956x motor system ICs (SBC). The combination of TLE9166 and TLE956x saves PCB space and provides excellent thermal performance.

    MOTIX™ TLE94xyz multi half-bridge ICs are pin- and software-compatible and consequently offer high flexibility and reduced design-in effort. Reduced system cost and small PCB footprint (up to 85% smaller footprint) are achieved by integration of multiple drivers and power stages (up to 12 half-bridges) in one device as well as through the feature optimization allowing to reduce external components. Infineon's MOTIX™ multi half-bridge ICs differentiate by an outstanding EMC concept and advanced diagnostic features for HS/LS level - improving overall system performance and reliability.

    What are the primary applications for MOTIX™ half-bridge ICs?
    • The many protection and diagnosis features of the MOTIX™ BTNxxxx single half-bridge devices make them ideal for safety-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 pre-tensioners, T-Case, HVAC control module.
    • The MOTIX™ TLE9166 is suited for door locks, safe locks, mirror fold and adjustment, mirror heating, electrochromic mirrors, incandescent bulbs, and LEDs. The combination with MOTIX™ TLE956x motor system ICs (SBC) offers high configurability and advanced features to address different loads. The chipset provides the scalability required to adapt to various system architectures, for example door control modules, front drives rear and zonal applications.
    • MOTIX™ TLE94xyz multi half-bridge ICs are a perfect solution for HVAC flap control, mirror adjustment and lighting and can also drive other inductive, capacitive, and resistive loads, including relays and bipolar stepper motors. Besides motor control, the products can drive any other inductive, capacitive and resistive load within the device electrical characteristics such as monostable or bistable relays.
