Pin Name

Description

1, 2, 3

VCC

Supply input, a 1µF capacitor is needed to supply internal charge pump. The capacitor return

should be connected directly to the GND pin.

4

SAS

SAS Disable, When this pin is pulled high to a voltage greater then 2.1V, the eFuse is turned off.

5

EN/FAULT

The EN/FAULT

pin is a tri−state, bidirectional interface. It can be used to enable or disable the

output of the device by pulling it to ground using an open drain device. If a thermal fault occurs,

the voltage on this pin will go to an intermediate state to signal a monitoring circuit that the device

is in thermal shutdown. It can also be connected to another device in this family to cause a

simultaneous shutdown during thermal events.

6, 7, 8

NC

Do not connect on PCB, internally connected for production purpose

9, 10, 11

VOUT

Output: eFuse controlled output; a 20µF capacitor is needed for over voltage protection stability.

The capacitor return should be connected directly to the GND pin.
