onsemi NCP51563 Gate Drivers

With high channel-to-channel spacing

The onsemi NCP51563 is a family of isolated dual-channel gate drivers with 4.5-A/9-A source and sink peak current respectively. Designed for fast switching to drive power MOSFETs, and SiC MOSFET power switches, the NCP51563 also offers short and matched propagation delays.

Two independent and 5 kVRMS (UL1577 rating) galvanically isolated gate driver channels can be used in any possible configurations of two low side, two high-side switches or a half-bridge driver with programmable dead time.

The gate drivers feature an enable pin shutdown of both outputs simultaneously when it is set low. The NCP51563 offers other important protection functions such as independent under-voltage lockout for both gate drivers and enable function.

Evaluation Board
NCP-NCV51563D2PAK7LGEVB


Evaluation Board Manual

The NCP-NCV51563D2PAK7LGEVB is an evaluation board for onsemi’s NCP/NCV51563. It consists of NCP51563 and 2 SiC MOSFETs in the standard D2PAK-7L package. The NCP51563 are isolated dual channel gate drivers with 4.5 A / 9 A source and sink peak current respectively.

Designed for fast switching to drive power MOSFETs, and SiC MOSFET power switches, the NCP51563 offers short and matched propagation delays. Two independent and 5 kVRMS internal galvanic isolation from input to each output and internal functional isolation between the two output drivers allows a working voltage of up to 1850 VDC. This driver can be used in any possible configurations of two low side, two high side switches or a half bridge driver with programmable dead time. An ENA/DIS pin enable or disable both outputs simultaneously when set high or low for ENABLE or DISABLE mode respectively. The NCP51563 offers other important protection functions such as independent under voltage lockout for both gate drivers and a Dead Time adjustment function.
