6EDL7151 Description
6EDL7151 is a gate driver IC for three-phase BLDC or PMSM motor drive applications. It provides three half-bridge drivers, each capable of driving a high-side and low-side N-type MOSFET. The gate driver is also provided with programmable dead time delays for preventing current shoot through between high-side and low-side switches in normal operation.
