STMicroelectronics L99H92
The L99H92 is designed to drive 4 external N-channel MOSFET transistors in single H-bridge or dual independent half bridge configuration for DC-motor control in automotive applications. The device has a low power mode (standby mode) where the current consumption is less than 5 µA. Each gate driver monitors independently its external MOSFET drain-source voltage for fault conditions.| Part No. | L99H92 |
