Pin Name
Description
ENA
Enable Input for MOSFET Switch A. This input pin is active high for the
SP2526A-1 and active low for the SP2526A-2
FLGA
An active-low and open-drained fault flag output fot channel A. It can indicate
current limit when ENA is active. In normal mode operation (ENA or/and ENB
is active), it also can indicate thermal shudown or undervoltage.
FLGB
An active-low and open-drained fault flag output fot channel B. It can indicate
current limit when ENB is active. In normal mode operation (ENA or/and ENB
is active), it also can indicate thermal shudown or undervoltage.
ENB
Enable Input for MOSFET Switch B. This input pin is active high for the
SP2526A-1 and active low for the SP2526A-2
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.
GND
Ground.
IN
Power supply input
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.
