PIN DESCRIPTIONS

PIN 1: CTLA

- Controls the turn-on/turn-off of

channel A MOSFET with TTL as

a control input. Active high for

SS6526-1 and active low for

SS6526-0.

PIN 2: FLGA

- An active-low and open-drained

fault flag output for channel A.

FLGA is an indicator for current

limit when CTLA is active. In

normal mode operation (CTLA

or/and CLTB is active), it also

can indicate thermal shutdown

or undervoltage.

PIN 3: FLGB

- An active-low and open-drained

fault flag output for channel B.

FLGB is an indicator for current

limit when CTLB is active. In

normal mode operation (CTLB

or/and CLTA is active), it also

can indicate thermal shutdown

or undervoltage.

PIN 4: CTLB

- Controls the turn-on/turn-off of

channel B MOSFET with TTL

as a control input. Active High

for

SS6526-1 and active low

for

SS6526-0.

PIN 5: OUTB - Channel B MOSFET switch

output.

PIN 6: GND

- Chip power ground.

PIN 7: IN

- Power supply input.

PIN 8: OUTA - Channel A MOSFET switch

output.
