IRS21814MPBF is a monotonic pulse converter and high-speed Gate Driver product from International Rectifier Corporation. This product is part of PMIC - Gate Drivers family and is primarily used for switching high power devices with high speed, low jittering and non-monotonicity. The IRS21814MPBF offers flexibility with selectable pulse width and oscillation frequency, as well as programmable waveform and synchronization.

The IRS21814MPBF is suitable for driving power mosfets, IGBTs, and thyristors. It has a unique capability of supporting a wide range of voltage and current levels and achieving higher efficiency than standard power conversion applications. IRS21814MPBF is also compatible with both standard and custom gate circuits. In addition, this product includes built-in protection circuits that provide over-temperature and over-voltage protection.

The IRS21814MPBF is an efficient, low-cost and high-speed power switch solution. Its programmable waveform controls minimize jitter and minimize power consumption. The IRS21814MPBF also offers multiple trigger inputs, such as frequency sync and pulse width synchronization for controlling switching times. In addition, it supports built-in self-test functions for back-up protection.

The circuit of IRS21814MPBF is designed by connecting two rectifier diodes and a capacitor to reduce the voltage and current ripple, allowing for higher efficiency gate drive than other gate drivers. The programmable waveform source is implemented with a voltage-controlled oscillator (VCO). The oscillator produces a sinusoidal waveform that can be tuned to the desired frequency by simply adjusting the amplitude of the control voltage to the VCO.

The circuit is powered directly from the main supply and only requires four external components: two diodes and two capacitors. The two diodes and capacitors are connected in series with the main supply to reduce the voltage and current ripple. The two capacitors are connected in parallel at the power supply end to provide a shunt supply for the oscillator.

The IRS21814MPBF includes several features to ensure smooth and reliable high-speed switching. The integrated high-current driver circuit drives the power devices efficiently and with minimal voltage and current drop. The high switching speed of the device, along with the silicon-controlled rectifier (SCR) protection, enables reliable high-speed switching. Furthermore, the device includes several protective mechanisms including over-temperature and over-voltage protection circuits.

The IRS21814MPBF provides flexible and reliable high-power switching in high-density applications. It has the advantages of programmable waveform, synchronization and adjustable frequency and pulse width that can be applied in different applications. The on-chip protection features protect the circuit from over-current, over-temperature, and over-voltage conditions. Furthermore, its low-cost construction and improved efficiency make it an ideal solution for high-density power switching applications.
