Hi team.
My customer try to use at power conditioner application.
And, could you tell me about this IC?
<Question>
①:I saw the block diagram at Figure 25 "Functional Block Diagram UCC 5320S and UCC 5390 S Split Outputs" and Table 4 in the data sheet.
Is it OK with the following processing in the Input ?
・VCC1 = 5 V
・GND 1 = 0 V
・IN + = 5 V (connected with VCC 1)
・IN- = 0 V or 5 V (ON at 0 V)
②:Is this understanding correct, about input (IN-) ?
・IN- ≧ 0.55 * VCC 1:OUT = L
・IN- ≤ 0.45 * VCC 1:OUT = H
③:The series resistance from the output is 5.1 Ω ± 5% and the power supply VCC 2 is 16 V ± 1.5 V.
Is this IC driving possible?
※Max current: (16 + 1.5) / (5.1 * 0.95) = 3.61 A is required?
④-1: What is the difference between Min and Typ of output current specification(below)?
Ioh: 2.4 A (min) / 4.3 A (Typ)
Iol: 2.2 A (min) / 4.4 A (Typ)
※ Only dispersion of Chip?
※Does it change depending on Chip variation and temperature dependence?
④-2: What is the constraint on 2.4 A of Min?
④-3: What happens to the output when driving can not be done?
Best regards,
