Switching the gate driver 

After  the  DEBUG  mode  is  activated  (section  4.4.1)  the  gate  driver  is  ready  to  be  switched  without  SPI 
communication. 
 
Before switching the gate driver, it has to be enabled: 

 

Connect 5V_DIG with EN (see Figure 7). 

 

nFLTA LED ON (close to signal connector) will indicate the driver ready signal. 

 
Now the gate can be controlled by the PWM signal: 

 

Connect 5V_DIG with PWM_xx OR connect a 5V signal generator between GND_DIG and PWM_xx and 
perform pulses (see Figure 7). 

 
Short Circuit (desaturation) or IGBT open detection: 

 

A IGBT desaturation (DESAT) event is indicated to the operator by turning off the corresponding nFLTA 
LED  (close  to  the  signal  connector).  The  gate  driver  is  than  looked  and  prevented  from  performing 
output pulses. It can be reactivated by the following sequence: 

 

Disconnect 5V_DIG from EN. Disabling the gate driver resets all error states. 

 

Connect 5V_DIG with EN. Enabling the gate driver again. 

 

The nFLTA LED will indicate driver again a ready signal. 

 

 

Figure 7 The testpads GND_DIG, 5V_DIG, PWM_xx, EN can be used to perform simple output pulses.  The 
testpads on the right picture simplify the access to the testpads (only revision “Sense_V1.2” and later).
