The LT1336CS#PBF is a half-bridge N-channel floating Power MOSFET Driver can drive the topside N-channel power MOSFETs operating off a high voltage (HV) rail of up to 60V. In PWM operation an on-chip switching regulator maintains charge in the bootstrap capacitor even when approaching and operating at 100% duty cycle. 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.

• Internal boost regulator for DC operation
• Adaptive non-overlapping gate drives prevent shoot-through
• Drives gate of top N-channel MOSFET above supply
• Top drive maintained at high duty cycles
• TTL/CMOS input levels
• Under-voltage lockout with hysteresis
• Separate top and bottom drive pins
