AP91352
SAS DISABLE +5V eFUSE WITH INTEGRATED ISOFET
Description
The eFuse is a 5V protection device with a bidirectional switch that
incorporates input slew rate control to reduce input surge current and
reverse current detection to prevent discharge to VCC from VOUT.
The eFuse protection features include under voltage lockout, a fixed
2.5A current limit, trimmed fast response over voltage protection and
thermal shutdown. The EN/FAULT line is a tri-state bidirectional
interface that can be used to disable the output by pulling the line low
through an external open drain device. If a thermal fault occurs, the
voltage on the pin will go to an intermediate voltage indicating a fault
and it can be connected to another device to cause simultaneous shut
down. The SAS pin is an ESD protected interface that allows direct
external control of the eFuse. Driving the SAS pin high pulls the
enable line low causing the eFuse to shutdown and enter a low
quiescent current state.
The integrated Isofet latches off when the reverse current is detected.
This can be reset only by triggering the under voltage lock out, by
EN/FAULT pin or when voltage on the output pin (VOUT) falls below
the supply pin voltage (VCC) in AP91352.
The AP91352 is available in a standard Green W-QFN3020-12
package and is RoHS compliant.

Notes:
6. Typical data is measured at TA = +25C, VCC = 5V. The maximum and minimum parameters values over operating temperature range are not tested in
production, they are guaranteed by design, characterization and process control.
7. The slew rate control is held in reset until the input voltage is greater than the UVLO rising threshold and Enable = High. The slew rate control is reset
when input voltage drops below UVLO falling threshold, Enable changes from High to Mid or Low, SA = High or reverse current detection.
8. Reverse current detection will latch off the Isofet switch; In AP91352, this condition can be reset by under voltage lock out, by EN/FAULT and SAS pin,
when VOUT falls below the supply pin voltage (VCC) by 100mV typical at TA = +25C, VCC = 5V.
