2ch Half-Bridge Gate Driver
Description
2ch Half-Bridge Gate Driver
BD16950EFV-C
General Description The BD16950EFV 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.
Features ■ AEC-Q100 Qualified(Note1) ■ 2ch Half-Bridge Gate Drivers ■ 4 external MOSFETs are Controlled Independently ■ Half-Bridge Control Modes are Selected by SPI ■ Slew Rates are Controlled with Constant Source /Sink Current.
■ 500 kHz Oscillation for Charge Pump.
■ 16bit SPI
(Note1) Grade1
