STMicroelectronics Automotive Octal Half-bridge Pre-driver Half-Bridge Driver for L99MH98 for N Channel MOSFETs

The STMicroelectronics Integrated Octal Half bridge pre driver dedicated to control up to sixteen N-channel MOSFETs. It is intended for DC motor control applications such as automotive power seat control or other applications. A 24 bit serial peripheral interface is used for configuring and controlling the eight half-bridges or four H‑bridge. SPI status registers provide high level diagnostic information such as supply voltage monitoring, the charge pump voltage monitoring, temperature warning and over temperature shutdown. Each gate driver monitors independently its external MOSFET drain source voltage for fault conditions.

• Independent channel driver up to 8 high side or 8 low side
• Support logic level and standard level MOSFETs
• Control of reverse battery protection MOSFET
• Fully configurable half bridge driver in case of fault occurrence
• Generator mode for power trunk or tailgate applications
• SPI configurable overvoltage threshold
