Test 4 – Typical Performance Waveforms –2 Channels Complementary Driver with Adjustable Dead Time

The NCD57253 can work as 2 channel complementary driver with single channel input with adjustable dead time.
To set the board as 2 channel driver, use this setup as a reference.
Make sure the power supplies & outputs of signal generators are powered off / disabled channel

1. VIN SET

a. For powering outputs by using external power supplies 

 open jumper

b. For using 5 V dc

dc converter – Set jumper to 5 V

c. For using different input voltage dc

dc converter – Set jumper to VCC

i. External power supplies with appropriate voltage need to be connected to VCC pin

2. ANB SET – Set to ON
3. DT SET – Set to DT (DT value is set by R7 value, see the datasheet)
4. B

IN SET – Set to INA

5. POWER UP the setup

(Legend: 

C1 – Input A (INA)
