Description
Parameters
EN Pin/Bit Enable
Control
This check box allows switching between the I
2
C controlled device
enable (checked) and pin controlled enable (unchecked). Leave this box
unchecked to enable by jumper or MCP2221 GP0.
Enable Bit
This check box sets the MIC23656 enable bit register. Check the box for
regulator enabling, uncheck for disabling. This bit value is considered
only if EN Pin/Bit Enable Control is checked.
Enable Delay
This spin box allows setting the available start time delays.
Current Limit
This spin box allows setting the available high-side current limits in order
to obtain the nominal load currents.
ON Time
This spin box allows setting the available ON-time values, that determine
slower (high T
ON
) or faster (lower T
ON
) switching frequencies.
Slew Rate
This spin box allows setting the available output slew rates.
Activate output
pull-down when
disabled
This check box activates automatic output pull-down resistor when the
MIC23656 is disabled.
Latch off after 4
OverTemp Cycles
This check box sets the latch off after four overtemperature (thermal
shutdown) cycles.
Force PWM
This check box sets forced PWM mode, regardless of output loading.
Disable 100% Duty
Cycle
This check box disables 100% duty cycle operation on high side when
V
IN
is close to V
OUT
. This feature is available only in High Range mode
(option MIC23656-SAYFT).
Read/Write
These buttons are used to read/write the registers that contain the
information described above.
Output Voltage
Voltage
This spin box allows setting the available output voltages. If the evalu-
ated chip option is MIC23656-YFT, MIC23656-HAYFT or
MIC23656-FAYFT, the Low Range option must be selected. If the evalu-
ated chip is MIC23656-SAYFT, High Range must be selected.
Read/Write
These buttons are used to read/write the registers that contain the infor-
mation described above.
GP0 control
Enable GP0 Control This check box allows enable control from the MCP2221 GP0 pin. If
unchecked, pin GP0 is Tri-State.
To enable access to this feature and allow pin enable control, uncheck
EN Pin/Bit Enable Control.
The enable jumper must first be removed, to prevent short-circuiting GP0
with the jumper.
GP0 active
This check box sets the state of MCP2221 GP0 pin. Leave unchecked to
disable the MIC23656 through Enable pin, or check the box to enable the
MIC23656 regulator.
