The main advantage of the integrated circuit IR2153 (R2153) is the built-in CMOS 555 type oscillator, which automatically generates the necessary drive signals for the half-bridge. This self-oscillating design allows the switching frequency to be adjusted using only two external components (a resistor RT and a capacitor CT). It completely eliminates the need for external microcontrollers or complex PWM generators, drastically reducing the number of components on the board, the overall manufacturing cost, and the design complexity.
Description
Specifications
Upgrade the performance, simplicity, and reliability of power supply electronic circuits, electronic transformers, and lighting systems with the popular integrated circuit IR2153 (R2153) Self-Oscillating Half-Bridge Driver from Infineon / International Rectifier. Specifically designed to combine an internal 555-type oscillator with an advanced high and low side half-bridge driver, this specialized IC drastically simplifies the design of power conversion circuits. It allows direct driving of Power MOSFETs and IGBTs in half-bridge configurations without the need for an external microcontroller or additional PWM signals. Thanks to the advanced floating channel isolation technology, it can operate with absolute stability at bus voltages up to 600V. Additionally, it features an integrated power supply Zener diode, undervoltage lockout (UVLO) protection, and programmable operating frequency via external resistor and capacitor. It is the most essential, efficient, and cost-effective choice for switch-mode power supplies (SMPS), electronic ballasts, and inductive applications.
Integrated Self-Oscillating Oscillator 555 & Design Simplicity
The main advantage of the integrated circuit IR2153 (R2153) is the built-in CMOS 555 type oscillator, which automatically generates the necessary drive signals for the half-bridge. This self-oscillating design allows the switching frequency to be adjusted using only two external components (a resistor RT and a capacitor CT). It completely eliminates the need for external microcontrollers or complex PWM generators, drastically reducing the number of components on the board, the overall manufacturing cost, and the design complexity.
Half-Bridge Drive up to 600V & Floating Channel Technology
Designed to handle high power voltages, the IR2153 features a High-Side channel with a floating channel architecture, allowing the safe driving of power switches at voltages up to 600V DC. It drives both the upper and lower Power MOSFET / IGBT with absolute precision and synchronization in half-bridge configurations. Additionally, it incorporates an internal fixed delay time (Deadtime 1.2μs) between switching, effectively preventing the shoot-through phenomenon and protecting the power semiconductors from damage.
Integrated Zener Diode, UVLO Protection & Wide Application
The IR2153 offers top protection and power supply convenience, featuring an internal 15.6V Zener diode on the VCC pin, allowing direct power supply from the high voltage line through a simple voltage drop resistor. At the same time, it integrates an Under-Voltage Lockout (UVLO) protection system with hysteresis, which keeps the output disabled until the supply voltage reaches safe operating levels. It is the most popular and reliable choice for electronic fluorescent lamp ballasts, SMPS power supplies, electronic halogen transformers, and DIY power projects.
