FUNCTION
5V Supply Input. Power-supply input and n-channel power MOSFET drain connection. If the 5V side
is not used, connect this pin to GND.
5V Load Output. n-channel power MOSFET source connection.
5V Supply Current-Limit Adjust. A resistor from this pin to LOAD5 determines the current limit for
the 5V pass connection. For better accuracy, dedicate one LOAD pin to connect to ILIM through
R ILIM . See the Applications Information section for more information.
Do Not Connect. Do not connect any signal to this pin.
Ground Connection
12V Supply Current-Limit Adjust. A resistor from this pin to LOAD12 determines the current limit for
the 12V pass connection. For better accuracy, dedicate one LOAD pin to connect to ILIM through
R ILIM . See the Applications Information section for more information.
12V Load Output. n-channel power MOSFET source connection.
12V Supply Input. Power-supply input and n-channel power MOSFET drain connection. If the 12V
side is not used, connect this pin to GND.
12V Enable Delay Control. A capacitor connected to this pin determines the enable delay accord-
ing to the equation: Enable Delay = C TIMER12 x (V REF12 /I TIMER ).
12V Voltage Ramp Control. A capacitor connected to this pin determines the voltage ramp of the
LOAD12 output during turn-on according to the equation: dV LOAD12 = 2 x (I VRAMP /C VRAMP12 ).
12V Autoretry Disable. Connect this pin to GND to disable automatic retry functionality; the device
latches off during an overtemperature fault. Leave this pin open to enable automatic retry function.
This pin contains a pullup (R PU12 ) to 5V. This pin is only sampled on device power-on. If the 12V
side is not used, connect this pin to GND.
