TLE9185QX

概要

The TLE9185QX is a three-phase driver IC with integrated power supply and support features in a PG-VQFN-48 power package for motor control in automotive applications.

The BLDC Driver IC provides main functions such as a 5 V low-dropout voltage regulator, three half-bridges for BDLC motor control, one current sense amplifier and one 32 bit SPI interface. The device includes diagnostic and supervision features and is intended to operate with 5.0 V microcontrollers.

特長

  • Low-drop voltage regulator 5 V, 250 mA for main supply
  • Three half-bridge gate drivers for external N-channel MOSFETs
  • Adaptive MOSFET gate control
  • One low-side capable current sense amplifier (CSA) with configurable gain for protection and diagnosis
  • Configurable wake-up sources
  • Six PWM inputs with upto 25 kHz PWM frequency
  • 32 bit serial peripheral interface (SPI) with cyclic redundancy check (CRC)
  • Periodic cyclic wake in Normal Mode, Stop Mode and Sleep Mode
