Function
Fault Flag A output. This open-drain output goes into an active-LOW state in response to under-
voltage, current limit or thermal shutdown conditions.
Enable A Input. This pin is the Channel B MOSFET switch driver control logic input. Both active-HIGH
(-1 suffix) and active-LOW (-2 suffix) logic devices are available.
Channel-A switch output (MOSFET Source). The output pin drives the load into ON and OFF states.
Ground. Power supply return for the internal circuitry of the IC. Connect both pins 4 and 6 together.
Channel C and D positive power supply input voltage. This is the switching MOSFET drain connection.
It is the channel C and channel D supply voltage input for the logic and the charge-pump circuit.
Channel-C switch output (MOSFET Source). The output pin drives the load into ON and OFF states.
Enable C Input. This pin is the Channel B MOSFET switch driver control logic input. Both active-HIGH
(-1 suffix) and active-LOW (-2 suffix) logic devices are available.
Fault Flag C output. This open-drain output goes into an active-LOW state in response to under-
voltage, current limit or thermal shutdown conditions.
Fault Flag D output. This open-drain output goes into an active-LOW state in response to under-
voltage, current limit or thermal shutdown conditions.
Enable D Input. This pin is the Channel B MOSFET switch driver control logic input. Both active-HIGH
(-1 suffix) and active-LOW (-2 suffix) logic devices are available.
Channel-D switch output (MOSFET Source). The output pin drives the load into ON and OFF states.
Ground. Power supply return for the internal circuitry of the IC. Connect both pins 4 and 6 together.
Channel A and B positive power supply input voltage. This is the switching MOSFET drain connection.
It is the channel A and channel B supply voltage input for the logic and the charge-pump circuit.
Channel-B switch output (MOSFET Source). The output pin drives the load into ON and OFF states.
Enable B Input. This pin is the Channel-B MOSFET switch driver control logic input. Both active-HIGH
(-1 suffix) and active-LOW (-2 suffix) logic devices are available.
Fault Flag B output. This open-drain output goes into an active-LOW state in response to under-
voltage, current limit or thermal shutdown conditions.
