DocID025037 Rev 1
B9
SREF
A
The reference used for the single-phase section regulation is available on this
pin with -125 mV offset. Connect through an RSREF-CSREF to GND to optimize
DVID transitions. Connect through RSOS resistor to the SFB pin to implement
small positive offset to the regulation.
A11
TM
A
Thermal monitor sensor.
Connect with proper network embedding NTC to the multi-phase power
section. The IC senses the power section temperature and uses the
information to define the VR_HOT signal and temperature monitoring.
By programming proper TCOMP gain, the IC also implements load-line and
IMON/ILIM thermal compensation for the multi-phase section.
In JMode, the pin disables the single-phase section if shorted to GND.
Pull up to VCC5 with 1 k
 to disable thermal sensor.
See Section 8 on page 39 for details.
B10
SPWM /
SEN
D
PWM output.
Connect to single-phase external driver PWM input. During normal operation
the device is able to manage Hi-Z status by setting and holding the pin to
a fixed voltage defined by PWMx strapping.
Connect to VCC5 with 1 k
 to disable the single-phase section.
A12
SENDRV
D
Enable driver.
CMOS output driven high when the IC commands the driver. Used in
conjunction with the Hi-Z window on the SPWM pin to optimize the single-
phase section overall efficiency. Connect directly to external driver enable pin.
B11
ILIM
A
Multi-phase section current limit.
A current proportional to the multi-phase load current is sourced from this pin.
Connect through a resistor RLIM to GND. When the pin voltage reaches 2.5 V,
the overcurrent protection is set and the IC latches. Filter through CLIM to GND
to delay OC intervention.
A13
VR_HOT
D
Voltage regulator HOT.
Open drain output, this is an alarm signal asserted by the controller when the
temperature sensed through the ST or TM pins exceed TMAX (active low).
See Section 8 on page 39 for details.
B12
TCOMP
A
Thermal monitor sensor gain.
Connect proper resistor divider between VCC5 and GND to define the gain to
apply to the signal sensed by the TM to implement thermal compensation for
the multi-phase section. Short to GND to disable temperature compensation
(but not thermal sensor). See Section 8 on page 39 for details.
