Opto-Isolated Interface
(Figure 5). Although the MIC5011
has no special input slew rate requirement, the lethargic
transitions provided by an opto-isolator may cause oscilla-
tions on the rise and fall of the output. The circuit shown
accelerates the input transitions from a 4N35 opto-isolator
by adding hysteresis. Opto-isolators are used where the
control circuitry cannot share a common ground with the
MIC5011 and high-current power supply, or where the
control circuitry is located remotely. This implementation is
intrinsically safe; if the control line is severed the MIC5011
will turn OFF.
Industrial Switch
(Figure 6). The most common manual
control for industrial loads is a push button on/off switch.
The
“
on
”
button is physically arranged in a recess so that in
a panic situation the
“
off
”
button, which extends out from the
control box, is more easily pressed. This circuit is compat-

ible with control boxes such as the CR2943 series (GE).
The circuit is configured so that if both switches close
simultaneously, the
“
off
”
button has precedence.
This application also illustrates how two (or more) MOSFETs
can be paralleled. This reduces the switch drop, and distrib-
utes the switch dissipation into multiple packages.
High-Voltage Bootstrap
(Figure 7). Although the MIC5011
is limited to operation on 4.75 to 32V supplies, a floating
bootstrap arrangement can be used to build a high-side
switch that operates on much higher voltages. The MIC5011
and MOSFET are configured as a low-side driver, but the
load is connected in series with ground.
Power for the MIC5011 is supplied by a charge pump. A
20kHz square wave (15Vp-p) drives the pump capacitor
and delivers current to a 100
μ
F storage capacitor. A zener
