DESCRIPTION
The LT®1336 is a cost effective half-bridge N-channel power MOSFET driver. The floating driver can drive the topside N-channel power MOSFETs operating off a high voltage (HV) rail of up to 60V (absolute maximum). In PWM operation an on-chip switching regulator maintains charge in the bootstrap capacitor even when approaching and operating at 100% duty cycle.

FEATURES
■ Floating Top Driver Switches Up to 60V
■ Internal Boost Regulator for DC Operation
■ 180ns Transition Times Driving 10,000pF
■ Adaptive Nonoverlapping 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
■ Undervoltage Lockout with Hysteresis
■ Operates at Supply Voltages from 10V to 15V
■ Separate Top and Bottom Drive Pins

APPLICATIONS
■ PWM of High Current Inductive Loads
■ Half-Bridge and Full-Bridge Motor Control
■ Synchronous Step-Down Switching Regulators
■ 3-Phase Brushless Motor Drive
■ High Current Transducer Drivers
■ Class D Power Amplifiers
