Description

The LT1336 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.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.ApplicationsPWM of High Current Inductive LoadsHalf-Bridge and Full-Bridge Motor ControlSynchronous Step-Down Switching Regulators3-Phase Brushless Motor DriveHigh Current Transducer DriversClass D Power Amplifiers
