Fig. 4 Recommended user interface of 2SC0435T (primary side)
Both ground pins must be connected together with low parasitic inductance. A common ground plane or wide
tracks are strongly recommended. The connecting distance between ground pins must be kept at a minimum.
Description of Primary Side Interface
General
The primary side interface of the driver 2SC0435T is very simple and easy to use.
The driver primary side is equipped with a 10-pin interface connector with the following terminals:
•
2 x power-supply terminals
•
2 x drive signal inputs
•
2 x status outputs (fault returns)
•
1 x mode selection input (half-bridge mode / direct mode)
•
1 x input to set the blocking time
All inputs and outputs are ESD-protected. Moreover, all digital inputs have Schmitt-trigger characteristics.
VCC
terminal
The driver has one VCC terminal on the interface connector to supply the primary side electronics with 15V.
