8.2.2 Detailed Design Procedure

To set the adjustable current limit value at 2 A, calculate R(CL) as follows:

Equation 3. GUID-72777A75-F543-4DE0-A638-1E03D2982D82-low.gif

To set the adjustable latch-off delay at 0.2 s, calculate C(DELAY) as follows:

Equation 4. GUID-83E8EC86-D22B-4A57-B648-0C0846A1500C-low.gif

TI recommends R(SER) = 10 kΩ for a 5-V MCU, and R(pullup) = 10 kΩ as the pullup resistor.
