8-Channel Gate Driver Improves Efficiency of 48-V Mild-Hybrid Vehicles

STMicroelectronics has introduced the L98GD8 gate driver, designed for 48-V automotive applications, offering enhanced efficiency, integrated protection, and diagnostics. This 8-channel gate driver is optimized for driving NMOS or PMOS FETs in 48-V systems, with eight fully configurable channels for flexible high- and low-side configurations. The driver provides rich diagnostics and protection for mild-hybrid systems and other 48-V loads, featuring individually programmable gate currents and per-channel diagnostics for various faults. The device includes features like logic built-in self-test, over/undervoltage monitoring, and an ultra-fast overcurrent shutdown. The L98GD8 is available in a 10x10-mm TQFP64 package with pricing starting at $3.94 for 1,000 pieces.
