描述 Description

The TLE9185QX is a multifunctional IC with integrated power supply, multiple half-bridges and support

features in an exposed pad PG-VQFN-48 power package. The device is designed for various motor control

automotive applications.

To support these applications, the BLDC Driver provides the 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 serial

peripheral interface (SPI).

The device includes diagnostic and supervision features, such as drain-source monitoring and open-load

detection, short circuit protection, configurable time-out and window watchdog, as well as overtemperature

protection.

The device is intended to operate with 5.0 V microcontroller.
