Si1040X

Notes:

a. Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-

on.

The Si1040X is ideally suited for high-side load switching in

portable applications. The integrated N-Channel level-shift

device saves space by reducing external components. The

slew rate is set externally so that rise-times can be tailored to

different load types.

Notes:

a. Surface Mounted on 1" x 1" FR4 board.

c. Pulse test; pulse width

≤ 300 µs, duty cycle ≤ 2 %.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation

of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect device reliability.
