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 Ph
where P Q is power dissipated under quiescent
current conditions, given by:
P
Q = V CC x I CC
where V CC is the application
device Supply Voltage
and I CC is the maximum Supply
Current given in the Electrical
Characteristics
and P Ph is power generated due to either one of
the phase outputs Ph1 or Ph2 being
active, given by:
P Ph = I OL x V OL
where I OL is the application Ph1 and Ph2
output currents
and V OL is the maximum Low Level
Output Voltage for the Ph1 and
Ph2 outputs given in the Electrical
Characteristics
