2ch Half-Bridge Gate Driver
The BD16952EFV is an AEC-Q100 automotive qualified
2-channel Half-Bridge Gate Driver, controlled by an
external MCU through a 16-bit Serial Peripheral
Interface (SPI). Independent control of low-side and
high-side N-MOSFETS allows for several MCU
controlled modes. A programmable drive current is
available to adjust slew-rates, in order to meet EMI and
power dissipation requirements. Diagnostics can be
read and reset by an external MCU.
