Sizing RPULLUP

The transistor output of ISOS510 operates in active, saturation, reverse, and cut-off regions, just like a regular transistor. To verify that the output does not get damaged when the output is saturated, the minimum value of RPULLUP can be calculated for a given pull-up voltage, VPULLUP, in Equation 1:

Equation 1. RPULLUP> VPULLUP- VCE(SAT)IC(MAX)

For the example of a feedback loop application, we can calculate the minimum required value for RPULLUP for a given VPULLUP of 10V, the maximum output voltage of the error amplifier (VCOMP(MAX) of 2.5V, and the maximum output current of the error amplifier is internally clamped at 1.6mA. The equation to calculate RPULLUP is shown in Equation 2:

Equation 2. RPULLUP> VPULLUP- VCOMP(MAX)ICOMP(CLAMP)= 10V - 2.5V1.6mA= 4.66k
