LTC1177-5/LTC1177-12
Isolated MOSFET Drivers
S
FEATURE
D
The LTC
1177-5/LTC1177-12 are isolated high side
MOSFET drivers. When used with an external N-channel
MOSFET, the LTC1177-5/LTC1177-12 form an isolated
solid state switch for reliable bounce-free switching op-
eration. The output does not require an auxiliary power
supply to maintain an on-state condition.
Two lead frame capacitors are used to transfer energy
from the input to drive the gate of the MOSFET and provide
the necessary isolation. Unlike optoisolated FET drivers,
the input current for the LTC1177-5 is only 1mA and
2.5mA for LTC1177-12. It also does not have the aging
problems endemic to optocouplers.
Both devices provide 2500V
RMS
(1 minute) or 3000V
RMS
(1 second) of output-to-input isolation.
The LTC1177-5/LTC1177-12 are available in the 18-pin
PDIP or 28-pin SW package.
