SP2526 +3.0V to +5.5V USB Power Control Switch

PIN ASSIGNMENTS

Pin 1 — ENA — Enable Input for MOSFET

Switch A. This input pin is active high for the

SP2526-1 and active low for the SP2526-2.

Pin 2 — FLGA — Fault Flag Output for Switch

Channel A. This open drain output pin pulls

low to indicate overcurrent, undervoltage

lockout, and thermal shutdown conditions.

Pin 3 — FLGB — Fault Flag Output for Switch

Channel B. This open drain output pin pulls

low to indicate overcurrent, undervoltage

lockout, and thermal shutdown conditions.

Pin 4 — ENB — Enable Input for MOSFET

Switch B. This input pin is active high for the

SP2526-1 and active low for the SP2526-2.

Pin 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.

Pin 6 — GND — Ground reference. Supply

return.

Pin 7 — IN — Supply Input. This input pin is

connected to the MOSFET drain of both

switches. Connect +3.0V to +5.5V to this

input pin. The voltage at this input pin also

supplies the internal circuitry.

Pin 8 — OUTB — Output for MOSFET Switch

Channel B. This is the output pin of the

MOSFET source of channel B, typically con-

nected to the switched side of the load.
