APPLICATION NOTES
MSK 4454 PIN DESCRIPTIONS
+VCC - Is the low voltage supply for all the internal
logic and drivers. A 0.1 µF ceramic capacitor in paral-
lel with a 10µF tantalum capacitor is the recommended
bypassing from the +VCC pin to the COM pin.
H INA, H INB, H INC - Are high active logic inputs for
signalling the corresponding phase high-side switch to
turn on. The logic inputs are compatible with standard
CMOS or LSTTL outputs. These logic inputs are inter-
nally zener clamped at 5.2 volts.
L INA, L INB, L INC - Are low active logic inputs for
signalling the corresponding phase low-side switch to
turn on. The logic inputs are compatible with standard
CMOS
or LSTTL outputs.
These logic numbers are
internally zener clamped at 5.2 volts.
AØ, BØ, CØ - Are the pins connecting the 3 phase
bridge switch options.
AV-, BV-, CV- - Are the connections from the bottoms
of the three half bridges. These pins get connected to
the COM pin. If current sensing is desired they may be
connected to the COM pin through a low value sense
resistor.
+VB - Is the connection used to provide power to the
floating high-side bootstrap supplies in the gate drive
circuitry.
V+ - Is the high voltage positive rail connection to the
tops of the three half bridges.
Proper power supply
bypassing must be connected from this pin to the COM
pin for good filtering. This bypassing must be done as
close to the hybrid as possible.
COM - Is the connection that all hybrid power supply
connections are returned to and bypassed to.
