The IRS2127SPBF is a high voltage, high current, low side, MOSFET/IGBT gate driver. It has two totally independent high and low side channels, an internal charge pump system and an integrated deadtime control circuit. Furthermore, it has an active clamping circuit, a PFM mode, a temperature protection circuit, fast overload recovery and input pins for the gate voltages. This makes the IRS2127SPBF one of the most versatile gate drivers available.

The IRS2127SPBF is designed to drive power MOSFETs and IGBTs in half-bridge configuration. It is also ideal for switching applications such as unipolar stepper motors, AC inductive loads and brushless DC motors. The IRS2127SPBF can easily drive the gate of power devices up to 600V, with a maximum current of 5A. The typical gate drive voltage is +12V, with a peak voltage of +20V. The current limit threshold is set to 2.4A, with a minimum gate drive threshold of 2V for the high side and 0.7V for the low side.

The IRS2127SPBF is powered from a single DC supply voltage range from 8 to 40 V. It has two output pins for simultaneous driving of the high and the low side MOSFETs, allowing the external circuit to be easily monitored. It uses an integrated charge pump to generate the required gate voltage and the deadtime can be adjusted by the on-chip control logic circuit. The output of the chip includes a power-on reset (POR) signal, an over-current protection (OCP) signal and an over-temperature protection (OTP) signal. The power-on reset prevents false triggering of the chip when the power is first turned on.

The IRS2127SPBF is an impressive device that offers users an abundance of features. It is powered from a single DC voltage and has two independent channels with a high output current capability. It also has an integrated deadtime control circuit and can be used for all types of switching applications with up to 600V of gate voltage. In addition, it includes all the necessary protection signals, such as power-on reset, over-current and over-temperature protection. All these features make the IRS2127SPBF the perfect choice for any switching application.
