Test 2 – Typical Performance Waveforms – Independent 2 Channels Driver
The NCD57253 can work as 2 independent channel driver.
To set the board as 2 independent 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 OFF
3. DT SET – Set to OFF
4. B
−
IN SET – Set to INB
5. POWER UP the setup
