LT1160 Datasheet PDF

●The LT1160CS#PBF is a half/full bridge N-channel Power MOSFET Driver that operates at supply voltages from 10 to 15V. 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 under-voltage 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.
