LTC1314
VPP
NC (Pin 2): Not Connected.
SHDN (Pin 3): Shutdown Output. When the output is high,
the external 12V regulator can be shut down to conserve
power consumption.
EN0, EN1 (Pins 4, 5): Logic inputs that control the voltage
output on VPP
with TTL/CMOS levels. Refer to Truth Table.
V
MOSFET gate driver DRV3. ESD protection device limits
input excursions to 0.6V below ground.
V
MOSFET gate driver DRV5. ESD protection device limits
input excursions to 0.6V below ground.
