描述 Description

The STGAP2D is a half-bridge gate driver which isolates the gate driving channels

from the low voltage control and interface circuitry.

The gate driver is characterized by 4 A capability and rail-to-rail outputs, making the

device also suitable for high power inverter applications such as motor drivers in

industrial applications.

The device integrates protection functions: dedicated SD and BRAKE pins are

available, UVLO and thermal shutdown are included to easily design high reliability

systems, and an interlocking function prevents outputs from being high at the same

time.

The input to output propagation delay results are contained within 75 ns, providing

high PWM control accuracy.

A standby mode is available in order to reduce idle power consumption.

Applications

• Motor driver for industrial drives, factory automation, home appliances and fans

• 600/1200 V inverters

• Battery chargers

• Induction heating

• Welding

• UPS

• Power supply units

• DC-DC converters

• Power Factor Correction
