The IR21364JTR is a high-voltage, high-speed power MOSFET and IGBT driver with three independent high and low side referenced output channels. Housed in a compact package, this driver IC is designed for applications requiring efficient control of power devices in a three-phase system.

Applications

• Three-phase motor drives
• Appliance motor control (e.g., washing machines, refrigerators)
• Industrial automation systems
• Power supplies
• Uninterruptible Power Supplies (UPS)

Features

• Floating channel designed for bootstrap operation up to +600V
• Tolerant to negative transient voltage, dV/dt immune
• Gate drive supply range from 10V to 20V
• Undervoltage lockout for all channels
• Matched propagation delay for all channels
• Cross-conduction prevention logic
• 3.3V logic compatible
• Internal dead-time of 520ns (typical)

Benefits

• Simplified gate drive circuitry for three-phase applications, reducing component count and board space.
• Robust operation in noisy environments due to high noise immunity and dV/dt capability.
• Enhanced system reliability with undervoltage lockout protection, preventing MOSFETs or IGBTs from operating in a linear region.
• Improved efficiency through matched propagation delays and integrated dead-time, minimizing switching losses.
• Direct interface with microcontrollers and DSPs due to its 3.3V logic compatibility.

Additional Details

The IR21364JTR utilizes International Rectifier's advanced high-voltage IC (HVIC) technology. It features a typical source and sink current capability of 200mA and 350mA, respectively, enabling it to drive a wide range of power MOSFETs and IGBTs. The internal dead-time ensures that the high-side and low-side switches in each phase leg are not simultaneously conducting, preventing shoot-through currents and increasing system efficiency. The device operates over a wide temperature range, typically from -40°C to +125°C. This driver also includes over-current shutdown feature.
