DESCRIPTIO

EATURE

UL Recognized

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.

File E151738 to UL1577

No Secondary Power Supply

Drives Any Logic Level FET

Low Input Current: 1mA Typ (LTC1177-5),

2.5mA Typ (LTC1177-12)

Turns On in 1ms Typ and Turns Off in 1ms Typ

2500V_RMSof Isolation Voltage

Isolates Input from High Voltage Transients at Load

Clean, Bounce-Free Switching

Current Limit

Two lead frame capacitors are used to transfer energy

fromtheinputtodrivethegateoftheMOSFETandprovide

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.

Small Outline Package

Both devices provide 2500V_RMS(1 minute) or 3000V_RMS

(1 second) of output-to-input isolation.
