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.

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

Product Detail

This demonstration circuit is an N-channel half-bridge for general purpose applications. The half-bridge can be driven with TTL/CMOS level signals into an LT®1336, which drives the N-channel MOSFETs. A self-contained highside driver regulator allows PWM operation to 100% duty cycle without discontinuities. By adding a controller IC and some other components in the space provided for prototyping, this demo board can be turned into a complete system solution. The half-bridge consists of four power MOSFETs, two paralleled topside MOSFETs and two paralleled bottom side MOSFETs.
