Typical application Example:
Requirement:
Redundant Bus Voltage = 12V (±10%, 10.8V to 13.2V)
(Junction Temperature). The Junction Temperature at
maximum load current (10A) and 60°C ambient is 95°C.
Load Current = 10A (assume through each redundant path)
Maximum Ambient Temperature = 60°C
Solution:
A single PI2126 for each redundant 12V power source
should be used, configured as shown in the circuit
schematic in Figure 18. PG pin is connected to ground and

Junction temperature increases. From Figure 10, at 95°C
R DS(on) will increase by 26%, then
maximum at 95°C
The fault pin (
) can be pulled to the system logic level
Maximum power dissipation is:
voltage via a resistor (10kΩ ), or it can be connected to the
input voltage (Vin) via a 25kΩ resistor.
Power Dissipation and Junction Temperature:
First use Figure 13 (Junction Temperature vs. Input
Current) to find the final junction temperature for 10A load
current at 60°C ambient temperature. In Figure 13
(illustrated in Figure 19) draw a vertical line from 10A to
intersect the 60°C ambient temperature line. At the
intersection draw a horizontal line towards the Y-axis
