TLE9263BQXV33XUMA1, or the Integrated Infineon, is a series of three-phase pre-driver ICs in the Infineon IC series. The ICs are designed for use in various applications, such as controlling brushed DC (BLDC) motors and managing power flow in Power electronics applications. The ICs can be used with gate driver ICs, where the having strong protection and diagnostic functions, they are suitable for high temperature and high reliable applications.

Application Field

The TLE9263BQXV33XUMA1 ICs are particularly well suited for applications in electric vehicles and industrial motor control, such as drive motors for pumps, fans, compressors, winches and conveyors. Furthermore, it is also used in battery operated motor control applications, as it enables easy implementation of a fully digital motor control with high efficiency and accuracy. Its special architecture allows a reduced amount of components, thereby minimizing EMI.

The TLE9263BQXV33XUMA1 can be used in HVAC motor drive solutions and small or large appliance motor control solutions such as microwave ovens and air-conditioners. For example, when used in cooling systems with EC fans, the TLE9263BQXV33XUMA1 can provide excellent thermal performance and energy savings.

Working Principle

The TLE9263BQXV33XUMA1 uses the H-bridge principle to provide a three-phase stepping motor drive solution. In this design, four transistors are arranged in the shape of an "H": two transistors in series to the load, while two transistors are connected in parallel. This arrangement switches the power to the motor by providing a current source and sink at a particular phase of the motor winding.

The transistors are driven by the high side (HS) and low side (LS) drivers which are built into the TLE9263BQXV33XUMA1 ICs. The HS and LS drivers can be configured in PWM or Step/Direction (S/D) operation. The PWM mode allows regulates the power provided to the motorwindings in a precise and effective manner, while the S/D mode is suitable for high holding torque applications with less noise.

The TLE9263BQXV33XUMA1 also has integrated protection features such as thermal shutdown, under voltage lockout (UVLO) and over temperature protection (OTP). It also has an on-chip Hall-effect sensors for motor speed feedback, as well as protection for the motor against over current and over-voltage. With the help of these features, the TLE9263BQXV33XUMA1 is an effective, reliable and robust solution for 3-phase motor control applications.
