Recently, STMicroelectronics announced the L98GD8 driver, designed for 48V automotive power architectures. The device includes eight configurable channels for driving MOSFETs in both high-side and low-side configurations and operates from a 58V supply. The L98GD8 integrates diagnostics and protection features to support safety and reliability in automotive applications.
The L98GD8 supports 48V powernet architectures used by vehicle manufacturers to expand mild-hybrid system capabilities. It enables operation of components such as integrated starter-generators, e-compressors, pumps, fans, and valves, contributing to higher electrical efficiency and reduced vehicle weight.
Features & Benefits:
- Eight independent, configurable outputs for high-side or low-side MOSFET driving
- Supports operation up to 58V
- Programmable gate current for managing switching noise and meeting EMC requirements
- Per-channel diagnostics for short-circuit, open-load, and short-to-ground faults
- Integrated logic BIST, hardware self-check voltage monitoring, and watchdog timer
- Overcurrent sensing with flexible configuration options
- Drain-source and shunt voltage monitoring for system reliability
- Ultrafast overcurrent shutdown with dual-redundant failsafe pins
- Battery undervoltage monitoring and ADC for temperature and battery sensing
- H-bridge current limiting and protection
The L98GD8 is automotive-qualified and meets industry requirements for safety, reliability, and electromagnetic compatibility. It is suitable for 48V automotive systems and motor control applications.
The L98GD8 is available in production now in a 10mm x 10mm TQFP64 package. Pricing starts at $3.94 for orders of 1000 pieces.
