T
SD
(MIN) is the minimum temperature required to
activate the AAT4618 over temperature protection.
With typical specification of 125°C, 115°C is a safe
minimum value to use.
For example, if an application is specified to oper-
ate in 50°C environments, the PCB operates at
temperatures as high as 85°C. The application is
sealed and its PCB is small, causing R
θ

to be
approximately 150 °C/W. Using Equation 2,

The AAT4618 is safe to operate at the minimum
current limit level of 500mA at 85°C.
