Primary Overcurrent (OC) Detector Trips Circuit
Breaker and Asserts I_FLT
Figure 3 below illustrates the behavior of the controller
to an OC event after the primary and secondary OC
detection circuits have been armed (upon the
application of an ENABLE LOW-to-HIGH transition
and after t
POR
) and steady-state operation has been
achieved. Note that the assertion of the controllers
PWRGD digital output occurs when the output load
voltage profile is higher than the controllers V
PGH
threshold voltage and the V
GS
of the external
MOSFET is higher than the controllers V
GSPGH
threshold voltage.
The use of an external C
PRIMARY
capacitor sets the
response time, t
POC
, of the primary OC detector
according to the internal V
PRIL
threshold voltage and
the CPRIMARY pin discharging current, I
PRI
, where
t
POC
= t
POCSENSE
+ C
PRIMARY
(V
PRIL
/I
PRI
). Prior to
triggering the primary OC detector (i.e., when
V
VCCSENSE
-V
SENSE
< V
CBP
), a 3mA current source is
enabled to hold the CPRIMARY pin voltage to the
internally-generated V
REG
voltage. When the primary
OC detector has been triggered, the 3mA current
source is first disabled and a 3礎 current sink is
enabled to discharge the external C
PRIMARY
. When
C
PRIMARY
has discharged below V
PRIL
, a default timer is
enabled. Once the default timer (t
POCSENSE
) times out,
the circuit breaker is tripped, the 3礎 current sink is
disabled, and the 3mA current source is enabled to
discharge C
PRIMARY
back to V
REG
quickly. Concurrently,
the GATE drive circuit is disabled and a higher
current, fault-mode pull-down current sink is enabled
at the GATE pin. The DISCH output goes high to
(optionally) drive external pull-down circuitry.
In the event that the CPRIMARY pin is left NC
(intentionally or otherwise), the overcurrent timer
default value is t
POCSENSE
(250祍 typical), as specified
in the ac specification table. Once the circuit breaker
is latched, the I_FLT digital output is asserted and the
PWRGD digital output becomes de-asserted when the
output voltage profile falls below the controllers V
PGL
threshold voltage or the V
GS
of the external MOSFET
falls below the controllers V
GSPGH
threshold voltage.
