Key Features
- 3-kVRMS reinforced isolation with integrated transformer in a compact SOP package eliminates external transformer design for automotive gate-driver bias supplies
- Regulated 1.5 W output from a 24 V automotive bus with AEC-Q100 Grade 1 qualification for reliable EV and HEV system integration
- Fixed regulated output voltage simplifies gate-driver power architecture for IGBT and SiC MOSFET drive stages in traction inverters
Applications
The UCC14240-Q1 provides isolated bias power for IGBT and SiC MOSFET gate drivers in automotive traction inverters, onboard chargers, and DC/DC converters where a 24 V primary bus must supply an isolated 1.5 W rail across 3-kVRMS isolation. Its integrated transformer and regulated output eliminate the external magnetics design burden, significantly reducing BOM complexity in EV and HEV power modules. Industrial motor drives operating from a 24 V intermediate bus also use this device when reinforced isolation is required between the control ground and the high-voltage power stage.

Frequently Asked Questions
What isolation voltage does UCC14240-Q1 provide, and why does that matter for SiC gate-driver applications?
The UCC14240-Q1 provides 3-kVRMS reinforced isolation between its primary and secondary sides, which is the minimum isolation level required by automotive safety standards for high-voltage traction inverter gate-driver bias supplies. SiC MOSFET gate drivers in 800 V EV bus systems are exposed to common-mode transients exceeding 1 kV, so the 3-kVRMS barrier ensures the low-voltage control circuits are protected from hazardous voltage coupling during fast switching events.
How does UCC14240-Q1 simplify a 24 V automotive gate-driver power supply design compared to a discrete flyback?
By integrating the isolation transformer, the UCC14240-Q1 eliminates the custom magnetics design, core selection, and winding specification steps that a discrete flyback requires. The module delivers a regulated 1.5 W output directly from a 24 V input in a standard SOP package, reducing PCB area, BOM count, and EMI design effort while meeting AEC-Q100 Grade 1 automotive qualification without additional component certification.
Which automotive powertrain systems benefit most from deploying UCC14240-Q1 for isolated bias rails?
EV traction inverters, hybrid onboard chargers, DC/DC boost converters, and active front-end rectifiers all benefit from the UCC14240-Q1 because each requires isolated 15 V to 20 V gate-driver bias rails with reinforced 3-kVRMS isolation on a 24 V automotive bus. The AEC-Q100 Grade 1 qualification and 1.5 W output capacity meet the bias power budgets of most single-channel IGBT or SiC gate-driver ICs used in these high-voltage powertrain designs.
