MOSFET 和 IGBT 栅极驱动器 – Applications

Improve the system reliability and efficiency of your automotive and industrial applications using TI gate drivers for high-power IGBTs, power MOSFETs, Silicon Carbide, and GaN.

Gate drivers in automotive

Ability to drive efficiently.
Demanding requirements to improve fuel efficiency mean automotive systems must shrink in size, lowering the overall weight of the vehicle. The ultra-low propagation delays in TI’s AECQ-100 qualified gate drivers help automotive systems efficiently switch power electronics at high frequencies to maintain a small footprint and reduce overall vehicle weight.

More efficient.
Propagation delays are as low as 15ns with TI gate drivers. Additionally, with peak currents ranging from 2.5A to 5A, output gate drivers can replace discrete totem pole solutions.

 

More reliable.
Handling ground bouncing experienced in harsh automotive environments is easier than ever with negative input voltages of -5V and wide temp range of -40 to 140 degrees Celius.

 

More flexible.
Inverting and non-inverting functions plus wide supply voltages of 4.5V to 35V allow you greater flexibility to drive wide bandgap switches, such as SiC, MOSFETs and IGBTs.

Gate drivers in industrial

The harsh environments and long-operating life standards of Industrial systems, in addition to demanding global efficiency requirements elevate a need for more robust and reliable electronics. With superior negative voltage handling, higher drive currents and shorter propagation delays, TI offer gate driver ICs that enable higher efficiency and noise handling to Industrial systems such as motor drives and control, factory automation, home automation, smart grid, and lighting.

TI gate driver benefits for Industrial applications:

  • Ability to handle noisy environments due to excellent negative voltage handling
  • Enables Higher efficiency thanks to higher drive currents and shorter propagation delays
  • High level of integration through addition of protection features
  • Reduced parasitic losses with the close proximity to the power switch
  • Ability to drive a variety of power switches such as MOSFETs and IGBTs due to wider supply voltages
