LT1336 Half-Bridge N-Channel Power MOSFET Driver with Boost Regulator Fea T Descrip T n Floating Top Driver Switches Up to 60V The LT 1336 is a cost effective half-bridge N-channel n Internal Boost Regulator for DC Operation power MOSFET driver. The floating driver can drive the n 180ns Transition Times Driving 10,000pF topside N-channel power MOSFETs operating off a high n Adaptive Nonoverlapping Gate Drives Prevent voltage (HV) rail of up to 60V (absolute maximum). In Shoot-Through PWM operation an on-chip switching regulator maintains n Drives Gate of Top N-Channel MOSFET charge in the bootstrap capacitor even when approaching Above Supply and operating at 100% duty cycle. n Top Drive Maintained at High Duty Cycles The internal logic prevents the inputs from turning on n TTL/CMOS Input Levels the power MOSFETs in a half-bridge at the same time. Its n Undervoltage Lockout with Hysteresis unique adaptive protection against shoot-through cur- n Operates at Supply Voltages from 10V to 15V rents eliminates all matching requirements for the two n Separate Top and Bottom Drive Pins MOSFETs. This greatly eases the design of high efficiency motor control and switching regulator systems. a T During low supply or start-up conditions, the undervoltage n PWM of High Current Inductive Loads lockout actively pulls the driver outputs low to prevent n Half-Bridge and Full-Bridge Motor Control the power MOSFETs from being partially turned on. The n Synchronous Step-Down Switching Regulators 0.5V hysteresis allows reliable operation even with slowly n 3-Phase Brushless Motor Drive varying supplies. n High Current Transducer Drivers L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
