Hi,
I am FAE, a distributor of TI products.
I received a question from a customer.
Before mounting the IC on the board and performing an operation test, the customer performs an inspection with an in-circuit Tester.
Among them, there seems to be a problem with the result when 1V is applied to VIN (1pin) and GND (7pin).
Normally, the resistance value between pins is 40Ω or less. (1V / 40Ω = 25mA)
In rare cases, the resistance value between pins is about 8Ω. (1V / 8Ω = 125mA)
This current seems to be the current that flows in the parasitic diode inside the IC. How much current normally flows in a normal product when 1V is applied?
Customers want to determine the threshold for normal and abnormal products through ICT inspection.
