The LT1160/LT1162 are cost effective half-/full-bridge N-channel power MOSFET drivers. The floating driver can drive the topside N-channel power MOSFETs operating off a high voltage (HV) rail of up to 60V.

The internal logic prevents the inputs from turning on the power MOSFETs in a half-bridge at the same time. Its unique adaptive protection against shoot-through currents eliminates all matching requirements for the two MOSFETs. This greatly eases the design of high efficiency motor control and switching regulator systems.

During low supply or start-up conditions, the undervoltage lockout actively pulls the driver outputs low to prevent the power MOSFETs from being partially turned on. The 0.5V hysteresis allows reliable operation even with slowly varying supplies.

The LT1162 is a dual version of the LT1160 and is available in a 24-pin PDIP or in a 24-pin SO Wide package.
