VRHOT Temperature Comparator
The MAX17080 features an independent comparator
with an accurate threshold (V HOT ) that tracks the ana-
log supply voltage (V HOT = 0.3V CC ). Use a resistor-
and thermistor-divider between V CC and GND to gener-
ate a voltage-SMPS overtemperature monitor. Place the
thermistor 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
Figure 9.
Fault Protection (Latched)
Output Overvoltage Protection (OVP)
The overvoltage protection (OVP) circuit is designed to
protect the CPU against a shorted high-side MOSFET
by drawing high current and blowing the battery fuse.
The MAX17080 continuously monitors the output for an
overvoltage fault. The controller detects an OVP fault if
the output voltage exceeds the set VID DAC voltage by
more than 300mV. The OVP threshold tracks the VID
DAC voltage except during a downward VID transition.
During a downward VID transition, the OVP threshold is
set at 1.85V (typ) until the output reaches regulation,
when the OVP threshold is reset back to 300mV above
the VID setting.
