A gate driver is a power device built to control and interface between gate signals and other high power components used in power electronics applications. The IR2132 is a popular gate driver integrated circuit used in many power electronics applications.

The IR2132 gate driver is a versatile 4 channel power IC that can be used to control the gate signals of IGBT and MOSFET circuits. This type of MOSFET and IGBT control requires a high current, high speed gate driver to switch the components on and off rapidly and accurately. The IR2132 accomplishes this with an isolated gate drive which can provide up to 3.2A peak gate current and enable switching frequencies of up to 10kHz.

An additional benefit of the IR2132 is its ability to drive isolated high side and low side MOSFET circuits. It features provides dead-time, under-voltage lock-out (UVLO) protection with built-in hysteresis for PINs that can be adjusted to the drive voltage, and temperature compensation for standard and disabled channels.

The IR2132 is extremely versatile, and can be used in a variety of applications. It is popularly used in switching mode power supplies, HVAC systems, motor control circuits, IGBT, and MOSFET circuits, programmable logic controllers, soft switching systems, and other industrial applications where high power and high speed gate drive is required.

The IR2132 works on the principle of charge pump technology, which uses a built-in circuit consisting of two capacitors, two diodes and an oscillator to produce negative voltage for the high side driver. The high side driver also has a separate pin for enabling the driver or powering it down, eliminating the need for an extra external driver. The high side driver also has an integrated pan-harmonic brake control, enabling faster shutdown and increase efficiency in the driving circuit.

The IR2132 contains four input pins and four output pins, enabling it to be used as a single or a double power supply gate driver. The voltage reference input pin is used to adjust the output voltage. The UVLO protection can also be turned on or off by adjusting this pin. The input signal pins can be driven either with a DC or a pulse signal, using an external isolation device to protect the gate driver from any overvoltage or spike on the input signal.

The output pins of the IR2132 can be set to either sourcing or sinking and adjustable speed up/speed down selectors are also available, which can be used to minimize switching losses in the system. An additional feature of the chipset is the active current limit (ACL) protection, which limits the gate current during turn-on or turn-off operation and keeps the gate driver from being damaged by high current spikes.

Overall, the IR2132 is a highly versatile, high-end gate driver integrated circuit that can be used in a variety of power electronics applications. Its built-in features, like the active current limit protection, adjustable speed up/speed down selectors and the pan-harmonic brake control make it an excellent choice for many power electronics applications including DC/DC converters, switch-mode power supplies, motor control circuits, IGBT and MOSFET circuits, and others.
