Fast Output Discharge for Capacitive Loads
In many applications where a switch controller is turned off by
either removing the PCB from the backplane or the ON pin is
reset, capacitive loading will cause the output to retain
voltage unless a bleed (low impedance) path is in place in
order to discharge the capacitance. The MIC2585 is equipped
with an internal MOSFET that allows the discharging of any
load capacitance to ground through a 50& to 170& path. The
discharge feature is configured by wiring the DIS pin to the
output (source) of the external MOSFET and is enabled if the
TRK pin is below 0.3V after the controller has been disabled
by a logic low signal received at the ON pin of Figure 1. See
the "Typical Application" circuit of Figure 1. A series resistor
is required from DIS to V
OUT
so that the maximum current of
25mA for the DIS pin is not exceeded.
Output Turn-Off Sequencing - No Tracking
There are many applications where it is necessary or desir-
able for the supply rails to sequence during turn-on and turn-
off, as is the case with some microprocessor requirements.
The MIC2585 can be configured to allow one output to shut
off first, followed by the other output. Figure 8 illustrates an
example circuit that sequences OUT1 and OUT2 in a first on
last off application. During start-up, capacitor C
DLY
allows for
V
OUT1
to turn on followed by V
OUT2
20ms later. Once the ON
pin receives a low signal by removing the PCB from the
backplane, or by an external processor signal, DIS1 and DIS2
will assert low. The external crowbar circuit connected from
the DIS2 pin will immediately bring V
OUT2
to ground while
V
OUT1
will discharge to ground through the 750& (680&
external, 70& internal) series path.
