LV8417CS-TE-L-H is a motor driver and controller from Texas Instruments and is categorized under the PMIC (Power Management IC) product family. The device combines a two-string, two-bank H-bridge motor driver with a dual brushless DC motor controller and embedded protection to ensure superior motor control performance. In addition, the device seamlessly integrates a dual-channel low-side gate driver and a dual-channel high-side gate driver, as well as a dual-channel PWMTimer. This makes it an ideal solution for applications such as high-physics and highly-efficient motor controls including automotive applications.

The application field of the LV8417CS-TE-L-H motor driver controller comprises automotive, HVAC, industrial and consumer applications. This motor driver controller has two types of working principles for providing higher efficiency and motor control performance. The first type is the switching power supply principle that is used for setting the chopper regulator to generate a PWM signal for controlling the motor speed. The second type is the self-oscillation power supply principle that is utilized for obtaining a high-speed response from the motor and reducing the noise radiation. Some of the more advanced features offered by the LV8417CS-TE-L-H include input voltage detection, current detection, temperature detection and protection, and overvoltage protection.

LV8417CS-TE-L-H has an advanced, built-in protection circuit that helps protect the device in case of overvoltage and thermal conditions. This protection circuit includes overvoltage protection, current limit protection, temperature protection and Lock-Up protection. It also includes an open-drain output signal that will detect the transient voltage failure condition and trip the protection. When the system detects a fault, it automatically sets the output of the device to low level to prevent the motor from being damaged.

The lower-side gate driver of the LV8417CS-TE-L-H provides a synchronous rectifier mode. This feature eliminates the need for external diodes and effectively reduces the power losses that are typically found in conventional motor drivers. The PWM timers of this motor driver incorporate advanced protection functions such as undervoltage lockout and thermal shutdown, as well as an adjustable power-on-reset delay timer for preventing false trigger when starting the motor. This motor driver also supports unipolar/bi-directional operation with automatic peak current detection for improving efficiency.

The dual-channel high-side and low-side gate drivers incorporated in the LV8417CS-TE-L-H enable it to operate in a variety of applications such as forward/reverse and 3-phase brushless DC motors. This motor driver also offers a variety of control interfaces including SPI, I2C, digital control and analog control. In addition, the LV8417CS-TE-L-H provides multi-speed operation and allows up to 8-bit resolution for digital control applications. In terms of hardware, the LV8417CS-TE-L-H is available in a 6-by-4-mm flat package and operates over a temperature range of -40°C to 105°C.
