Note: Available in Tape and Reel. Append the letters “TR” to
the part number.
TJ = TA + (PD x θJA).
The θJA numbers are guidelines for the thermal
performance of the device/pc-board system. All of the
above assume no ambient airflow.
POWER DISSIPATION
Rsense Power Dissipation: 0.36 Ω x Iport2
Rds_ON Power Dissipation: 0.3Ω x Iport2
• Pport_AF = 15.4 W
==> PRsense = 28.2mW
PRds_ON = 23.4mW
• Pport_AT = 30 W
==> PRsense = 107 mW
PRds_ON = 88.5mW
** Calculated for Supply input Voltage of 55V
INTERNAL 3.3V VOLTAGE REGULATOR IS USED
PD69108 self power dissipation: 1.1 W
EXTERNAL 3.3V VOLTAGE REGULATOR IS
USED
PD69108 self power dissipation: 0.5 W
PD69108 8 ports AF Application Power dissipation = 1.1 W + PD69108 AF 8 ports Application Power dissipation =
[ 8 x (28.2 mW + 23.4mW) ] = 1.51W
0.5 W + [ 8 x (28.2mW + 23.4mW) ] = 0.91W
PD69108 8 ports AT Application Power dissipation = 1.1 W + PD69108 8 ports AT Application Power dissipation =
[ 8 x (107 mW + 88.5mW) ] = 2.66W
0.5 W + [ 8 x (107 mW + 88.5mW) ] = 2.06W

Notes:
Exceeding these ratings can cause damage to the device. All voltages are with
respect to ground. Currents are marked positive when flowing into specified
terminals and marked negative when flowing out of a specified terminal.
