10.2.2.1 Maximum Junction Temperature Check

For a 200 mA current limit:

  • The maximum driver output current limit, IO(LIM) = 250 mA (allowed for current limit tolerance).
  • The maximum voltage drop is given with VDS(ON) = 1.75 V.

This causes a power consumption of:

Equation 1. TIOL111 TIOL1113 TIOL1115 eq3_sllsev5.gif

For a 5 mA LDO current output,

Equation 2. TIOL111 TIOL1113 TIOL1115 eq4_sllsev5.gif

Total power dissipation,

Equation 3. TIOL111 TIOL1113 TIOL1115 eq5_sllsev5.gif

Multiply this value with the Junction-to-ambient thermal resistance of θJA = 68.1°C/W (taken from the Thermal Information table) to receive the difference between junction temperature, TJ, and ambient temperature, TA:

Equation 4. TIOL111 TIOL1113 TIOL1115 eq6_sllsev5.gif

Add this value to the maximum ambient temperature of TA = 105°C to receive the final junction temperature:

Equation 5. TIOL111 TIOL1113 TIOL1115 eq7_sllsev5.gif

As long as TJ-max is below the recommended maximum value of 150°C, no thermal shutdown will occur. However, thermal warning may occur as the junction temperature is greater than TWRN.

Note that the modeling of the complete system may be necessary to predict junction temperature in smaller PCBs and/or enclosures without air flow.
