The UCC275xx-Q1 family provides the highest power efficiency, reliability and flexibility compared to existing solutions for automotive applications, such as powertrain, bi-directional converters (12- to 48-V and 12- to 400-V input), onboard charging, traction inverters, advanced driver assistance systems (ADAS), safety, headlamps and instrumentation clusters.

The ultra-low propagation delays in the UCC275xx-Q1 family help automotive systems efficiently switch power electronics at high frequencies to maintain a small footprint and reduce overall weight.

Features include;

– Integrated solution saves space and enables highest efficiency: with peak currents ranging from 2.5 to 5 A and propagation delays of less than 15 ns, TI’s automotive output-stage drivers can replace discrete totem pole solutions. This cuts down board space, reduces system cost and enables the gate drivers to be placed closer to the switch, which cuts down parasitic inductances and improves efficiency.

– Reliable and robust: The wide temperature range of -40 to 140C and negative input voltage of -5 V enables handling of ground bouncing experienced in harsh environments.

– Design flexibility to support a wide input voltage range: Supports 4.5 V to 35 V to drive wide bandgap switches, such as SiC, MOSFETs and IGBTs that are capable of withstanding high temperatures without compromising efficiency. Additionally, the inverting functions of the UCC27518A-Q1 and UCC27519A-Q1, and non-inverting functions of the UCC27531-Q1, UCC27517A-Q1, UCC27519A-Q1 and UCC27524A-Q1 add the flexibility needed to handle different types of inputs.

Evaluation modules cost $49.00. UCC27531-Q1 and UCC27532-Q1 single-channel gate drivers are available in a 6-pin SOT-23 package for $0.88. The UCC27517A-Q1, UCC27518A-Q1 and UCC27519A-Q1 single-channel gate drivers are available in a 5-pin SOT-23 package for $0.61 and the UCC27524A-Q1 dual-channel gate driver is available in an 8-pin MSOP-PowerPAD package for $1.00 (all 1000).
