Application Hints

IMPORTANT INFORMATION

This data sheet contains only product-specific data. All data that apply to

the whole type series of SCALE drivers is given in the document entitled:

“Description and Application Manual for SCALE Drivers”. In particular, this

manual contains a detailed description of the concept of the SCALE

drivers, a description of the function of all terminal pins as well as other

important application hints.

Overview and application

The SCALE driver 2SD315AI is a two channel driver for power MOSFETs and IGBTs. The

2SD315AI combines compact mechanical dimensions and a simple electrical interface

with very high output currents, high drive power and a special high isolation. This driver

can thus be used in almost all conceivable applications, especially for parallel circuits,

high-power modules and modules with reverse voltages up to 1700V. When used as a

half-bridge driver, the 2SD315AI can directly generate any dead times that may be

required.

Output power and self-heating

The specified output power of the driver totals 6W (3W per channel). In the case of a

drive power of 6W, the typical input power of the driver is about 7W; the losses due to

the driver total about 1W. Because CONCEPT cannot predict how the drivers will be

incorporated in the user’s application, no binding recommended value for self-heating

and thus for the maximum useful output power at high ambient temperatures can be

made. It is consequently recommended to check the self-heating of the system,

especially when it is used at higher temperatures.

For the calculation of the exact output power, reference should be made to Application
