Figure 10. THRM Configuration
When SHDN goes low, the MAX17480 enters shutdown
mode. PWRGD is pulled low immediately and forces all
DH and DL low, and all three outputs are discharged
through the 20Ω internal discharge FETs through the CSN
pin for core SMPSs and through the OUT3 pin for NB
SMPSs.
The MAX17480 features an independent comparator with

voltage-SMPS overtemperature monitor. Place the thermis-
tor as close as possible to the MOSFETs and inductors.
Place three individual thermistors near to each SMPS to
monitor the temperature of the respective SMPS. When
core SMPSs are in combined-mode operation, the cur-
rent-balance circuit balances the currents between
core SMPS phases. As such, the power loss and heat
in each phase should be identical, apart from the
effects of placement and airflow over each phase.
Single thermistors can be placed near either of the
phases and still be effective for core SMPS temperature
monitoring, and one thermistor can be saved. See
