US semiconductor firm Texas Instruments (TI) has launched a 120-V automotive grade half-bridge gate driver, touted to be the fastest in the sector, offering negative voltage handling capability on the high-side pin for hybrid vehicles.
With a propagation delay at 15ns in keeping with short rise and fall times, the driver demonstrates a delay matching of 1ns for 12-V to 48-V DC/DC power supplies.
The UCC27201A-Q1 high-side/low-side gate driver offers also claims to display noise tolerance, while its 120-V bootstrap diode makes way for N-channel MOSFET control. In this way, the latter eliminates need for external discrete diodes.
With the system allowing efficient switch at high frequencies, the gate driver has led to the reduction of size and weight of magnetic and heat sinks. This results into paring down extra pounds and translates into higher mileages.
For protecting the power supply, a tightest delay matching of 1ns becomes effective towards protecting the power supply from suffering short-circuits and failure.
Moreover, the device is capable of cutting down cycle-by-cycle by switching losses, boosting power conditioning efficiency and making way for the system to switch at high-frequency magnitude of hundreds of kilohertz, ensuring smaller system size and weight.
The UCC27201A-Q1 is capable of being used in conjunction with any digital controller, such as, UCD3138, C2000 LaunchPad development kits and ultra-low-power MSP430TM microcontrollers.
Beside, the driver system empowers designers to develop and debug applications with the help of TINA-TI and PSpice models.
