PIN ASSIGNMENTS

PIN NUMBER

PIN SYMBOL

DESCRIPTION

1

ENA

Enable Input for MOSFET Switch A. This input pin is active

high for the SP2026-1 and active low for the SP2026-2.

2

FLGA

Fault Flag Output for Switch Channel A. This open drain

output pin pulls low to indicate overcurrent and thermal

shutdown conditions.

3

FLGB

Fault Flag Output for Switch Channel B. This open drain

output pin pulls low to indicate overcurrent and thermal

shutdown conditions.

4

ENB

Enable Input for MOSFET Switch B. This input pin is active

high for the SP2026-1 and active low for the SP2026-2.

5

OUTA

Output for MOSFET Switch Channel A. This is the output pin

of the MOSFET source of channel A, typically connected to

the switched side of the load.

6

GND

Ground reference. Supply return.

7

IN

Supply Input. This input pin is connected to the MOSFET drain

of both switches. Connect +2.7V to +5.5V to this input pin.

The voltage at this input pin also supplies the internal circuitry.

8

OUTB

Output for MOSFET Switch Channel B. This is the output pin

of the MOSFET source of channel B, typically connected to the

switched side of the load.
