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.
