A sophisticated high voltage technology allows the TLE9180D-31QK to support applications for single and mixed battery systems with battery voltages of 12 V, 24 V and 48 V even within tough automotive environments in combination with high motor currents. Therefore bridge, motor and supply related pins can withstand voltages of up to 90 V. Motor related pins can even withstand negative voltage transients down to - 15 V without damage. All low- and high-side output stages are based on a floating concept and its driver strength allows to drive lowest RDSON MOSFETs common on the market. In 12 V applications the gate driver IC is capable of driving 6 MOSFETs, each with a max. total gate charge of QgTOT = 300 nC, at a frequency of up to 20 kHz. An integrated SPI interface is used to configure the TLE9180D-31QK for the application after power-up. After successful power-up parameters can be adjusted by SPI, monitoring data, configuration and error registers can be read. Cyclic redundancy check over data and address bits ensures safe communication and data integrity. GND related bridge currents can be measured with 3 integrated current sense amplifiers. The outputs of the current sense amplifiers support 5 V ADCs and the robust inputs can withstand negative transients down to -10 V without damage. Gain and zero current voltage offset can be adjusted by SPI. The offset can be calibrated. Diagnostic coverage and redundancy have increased steadily in recent years in automotive drive applications. Therefore the TLE9180D-31QK offers a wide range of diagnostic features, like monitoring of power supply voltages as well as system parameters. A testability of safety relevant supervision functions has been integrated. Failure behavior, threshold voltages and filter times of the supervisions of the device are adjustable via SPI. The TLE9180D-31QK is integrated in a LQFP64 package with an exposed pad. Due to its exposed pad the gate driver IC provides an excellent thermal characteristic.
