TPS23851 / Icut , Power Class calculation

Ryuji
Guru 20090 points
Hello,
 
Our customer use TP23851 as below conditions.
 
<A>
Rsense : 0.5Ω
Icut : 374mA
Vsen : 243.8mV peak, 30mV average
Isen : 487.6mA peak, 60mA average
<B>
Rsense : 0.5Ω
Icut : 374mA
Vsen : 287.8mV peak, 60mV average
Isen : 575.6mA peak, 120mA average

Could you please kidnly let me know about below questions?
-------------------------
<Question 1>
In above conditions, average current under the Icut but peak current over the Icut.
Should we set the Icut above the peak current ?
If yes, are below register setting correct ?
==
ICUT Pn : 101 (=592mA)
HPWN:1
SNDI:1

<Question 2>
Customer's setting is Class1(0.44～3.84W).
Should we set the Class2 for abobe <B> conditions ?
My PD class calculation is as below.
 
<A>= 48V * 60mA = 2.88W
<B>= 48V * 120mA =5.76W
-------------------------
