STMicroelectronics has introduced the L98GD8, an advanced 8-channel automotive gate driver designed to optimize 48V mild-hybrid power systems. Engineered for flexibility, the device can operate from a 58V supply and supports both high-side and low-side MOSFET configurations. It integrates extensive diagnostic and protection features to ensure safety, reliability, and superior performance across a wide range of automotive applications.
The adoption of 48V power architectures enables car manufacturers to enhance mild-hybrid systems by supporting higher-efficiency components such as integrated starter-generators, e-compressors, pumps, and fans. These systems help improve energy recovery, reduce vehicle weight, and meet stricter global emission standards. The L98GD8 simplifies this transition by providing engineers with a compact, integrated solution for controlling MOSFETs in multiple topologies, including H-bridges for DC motor control and peak-and-hold operation for valves. Its programmable gate current allows precise management of switching noise, ensuring compliance with EMC requirements.
Built to meet stringent automotive qualification standards, the L98GD8 features per-channel diagnostics for open-load, short-to-battery, and short-to-ground conditions. Additional built-in protection includes overcurrent sensing, logic self-tests, voltage monitoring, and fail-safe mechanisms for dependable system operation. The device also integrates an ADC for temperature and voltage tracking, as well as ultrafast overcurrent shutdown and current limiting for H-bridge configurations. Now available in a compact 10mm x 10mm TQFP64 package, the L98GD8 is priced from $3.94 for orders of 1,000 units.
