Turnon/Turnoff Adjust
The PCB contains a single, 10-Ω gate resistor (R4) and a short bus wire in place of diode D2. This simple
configuration sets the peak current at approximately 3 A, with turnon/ turnoff characteristics the same. The
PCB has provisions for the user to install the D2 and D3 diodes and R4 and R5 resistors. This allows the
user to evaluate device operation with different on/off characteristics. This is shown in
The
turnon characteristics can also be adjusted with the value of R2, which connects VC to VCC2. As shipped,
R2 is set to 0
Ω,
but the user can change this and examine the effects on turnon characteristics.
