B.1 Power Supplies
Power is supplied to the Coyote via the friction-lock connector terminal at J2. The Coyote
has an onboard +5 V switching power regulator from which a +3.3 V linear regulator
draws its supply. Thus both +5 V and +3.3 V are available. The Coyote is protected
against reverse polarity by a diode at D1 as shown in Figure B-1.
The input voltage range is from 8 V to 40 V DC.
There is provision on the printed-circuit board for a transorb to be installed at TVS1 in
parallel with C1 to provide suppression for positive noise pulses above 51 V. This part is
only needed when the Coyote will be used in industrial environments where a clean source
of power cannot be guaranteed, and is not part of the normal factory build.
