Typical Application
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.
