NCD57200数据手册集成电路（IC）的栅极驱动器规格书PDF

描述 Description

NCD57200 is a high voltage gate driver with one non−isolated
low side gate driver and one galvanic isolated high or low side gate
driver. It can directly drive two IGBTs in a half bridge configuration.
Isolated high side driver can be powered with an isolated power supply
or with Bootstrap technique from the low side power supply.

The galvanic isolation for the high side gate driver guarantees
reliable switching in high power applications for IGBTs that operate
up to 800 V, at high dv/dt. The optimized output stages provide a mean
of reducing IGBT losses. Its features include two independent inputs
with deadtime and interlock, accurate asymmetric UVLOs, and short
and matched propagation delays. The NCD57200 operates with its
VCC/VB up to 20 V.

特性 Features
