PIN FUNCTIONS

LTC1981:

V_CC(Pin 5): Input Supply Voltage. Range from 1.8V to

GDR (Pin 1): Gate Drive Ready Active High Open Drain

Output. Used to indicate when the gate drive output is

greater than 90% of its final value.

5.5V.

LTC1982:

GND (Pin 2): Ground.

SHDN 1 (Pin 1): SHDN 1 Active Low Input. Used to shut

down the GATE 1 charge pump and force the GATE 1

output pin to ground.

SHDN (Pin 3): SHDN Active Low Input. Used to shut down

the part and force the GATE output pin to ground.

GND (Pin 2): Ground.

GATE (Pin 4): Gate Drive Output to an External High Side

Switch. Fully enhanced by internal charge pump. Con-

trolled by the SHDN input pin. Output voltage on this pin

will be approximately 2.5 times V_CCor 7.25V, whichever is

less.

SHDN 2 (Pin 3): SHDN 2 Active Low Input. Used to shut

down the GATE 2 charge pump and force the GATE 2

output pin to ground.
