Infineon Technologies TLE92104

The TLE92104-131QX and TLE92104-232QX are the new devices in the multiple MOSFET driver IC family in addition to the recently introduced TLE92108. TLE92104 drivers are designed to control up to four half-bridges (up to 8 N-channel MOSFETs) with one packaged device. Target applications involve automotive DC motors used in power seat modules, power closure systems, and many more. 24-bit Serial Peripheral Interface (SPI) enables configuration of the device and control of the half-bridges and offers a wide range of diagnostic features.

Key features

• Up to 4-fold half-bridge (8 N-channel) MOSFET driver outputs
• Adaptive multi-stage MOSFET gate control
• 3 PWM inputs and up to 2 x flexible current sense amplifiers (for HS, LS and in phase)
• Sophisticated protection concept, incl. detailed off-state diagnostics

Additional features

• Integrated dual-stage charge pump supporting an external N-FET for reverse battery protection and usage of normal level MOSFETs for motor control
• Configurable motor brake mode and low current consumption also in sleep mode 

Additional Benefits

• Enables cost and board space improvements
• The adaptive driver allows balancing of power dissipation vs. EMC performance, adjusts for MOSFET type and lot-to-lot variations
• High configurability

Applications

• Seat module and extended functions
• Closure systems (e.g. trunk opener, sliding door, sun-roof)
• Central door lock
• Body control module

Available tools

TLE92104-23QX APPKIT:

• This application kit contains one of the Multi MOSFET Driver ICs of the TLE92104-23QX and a typical application circuit, including 4 MOSFET half-bridges to drive up to 4 DC motors. It is a simple and easy-to-use tool to evaluate hardware and software functionalities. The application board can be connected via a UIO stick with the computer to evaluate its features via ConfigWizard (a graphical user interface) which can be found in the Infineon Toolbox.
