IR51H420 Product details

Description
The IR51H(D)XXX are complete high voltage, high speed, selfoscillating half-bridge circuits. Proprietary HVIC and latch immune CMOS technologies, along with the HEXFET® power MOSFET technology, enable ruggedized single package construction. The front-end features a programmable oscillator which functions similar to the CMOS 555 timer. The supply to the control circuit has a zener clamp to simplify offline operation. The output features two HEXFETs in a half-bridge configuration with an internally set deadtime designed for minimum cross-conduction in the half-bridge.

Features
• Output Power MOSFETs in half-bridge configuration
• High side gate drive designed for bootstrap operation
• Bootstrap diode integrated into package (HD type)
• Accurate timing control for both Power MOSFETs
    Matched delay to get 50% duty cycle
    Matched deadtime of 1.2us
• Internal oscillator with programmable frequency
• 15.6V Zener clamped Vcc for offline operation
• Half-bridge output is out of phase with RT
• Micropower startup

About International Rectifier


International Rectifier (IR) was an American company that specialized in the design and manufacture of power management and power control semiconductors.
The company was founded in 1947 and was headquartered in El Segundo, California.
IR provided a wide range of products including power management ICs, power MOSFETs, IGBTs, and other power control products.
The company's products were used in various applications such as computing, telecommunications, and industrial automation.
IR was known for its expertise in power management and control technology and its ability to deliver high-quality and reliable products to its customers.
In 2014, IR was acquired by Infineon Technologies, a leading provider of power management and control products and other semiconductor solutions.
The International Rectifier brand is no longer in use, but its technology and products continue to be a part of Infineon's portfolio.
