Power Dissipation
1) Maximum allowable Power Dissipation, P
D
,
is shown plotted against Ambient Temperature,
T
A
, in the accompanying Power Derating Curve,
indicating the Safe Operating Area for the device.
2) Power consumed by the device, P
T
, can be
calculated from the equation:
P
T
= P
Q
+ P
PhHi
+ P
PhLo
where
P
Q
is power dissipated under quiescent
current conditions, given by:
P
Q
= Vcc x Icc
where Vcc is the application
device Supply Voltage
and
Icc is the maximum Supply
Current given in the Electrical
Characteristics
and
P
PhHi
is power generated due to either one of
the phase outputs Ph1Hi or Ph2Hi being
active, given by:
P
PhHi
= I
OL
x V
OL
where I
OL
is the application Ph1Hi and Ph2Hi
output currents
and
V
OL
is the maximum Low Level
Output Voltage for the Ph1Hi and
Ph2Hi outputs given in the Electrical
Characteristics
and
P
PhLo
is power generated due to either one of
the phase outputs Ph1Lo or Ph2Lo being
active, given by:
P
PhLo
= I
OH
x (V
CC
- V
OH
)
where I
OH
is the application Ph1Lo and Ph2Lo
output currents
and
Vcc is the application device Supply
Voltage
and
V
OH
is the minimum High Level
Output Voltage for the Ph1Lo and
Ph2Lo outputs given in the Electrical
Characteristics
