IR2130S Driver IC: Pinout, Specification and Features [FAQs]

IR2130S Introduction

The IR2130S is a high-voltage, high-speed driver IC designed for controlling power MOSFETs and IGBTs, featuring three independent high-side and low-side output channels. It supports operation up to 600V, using proprietary HVIC technology for robust monolithic construction.

This IC is compatible with CMOS/LSTTL logic inputs down to 2.5V and includes a ground-referenced operational amplifier for bridge current feedback via an external sense resistor. Key features include a current trip function that disables all outputs during over-current conditions and an open-drain FAULT signal for shutdown indications. Matched propagation delays and high pulse current output stages optimize performance in high-frequency applications.

IR2130S Package

The IR2130S uses a 28-SOIC package, a standard surface-mount package featuring high integration and compact size, ideal for space-constrained circuit designs. The package width is 7.5mm, with a thickness of approximately 2.35mm, offering low thermal resistance. Additionally, its 28 pins are arranged compactly to ensure efficient signal transmission and stable electrical performance.

The 28-SOIC package of the IR2130S provides excellent mechanical strength and soldering reliability, making it suitable for automated reflow soldering processes. With a pin pitch of 1.27mm, it simplifies layout design and reduces wiring complexity.

How to Use IR2130S?

First, connect VCC to the low-side driver and logic power supply, and VB1, VB2, VB3 to the high-side floating supplies. Ensure all ground connections are correctly established, including VSS as the logic ground, VS1, VS2, VS3 as the return paths for the high-side floating supplies, and VS0 for the low-side return and the positive input of the current amplifier. Use filter capacitors during power connection to minimize noise interference.

Next, connect HIN1, HIN2, HIN3 to the high-side drive signals, and LIN1, LIN2, LIN3 to the low-side drive signals. The logic inputs are compatible with CMOS or LSTTL outputs, with a minimum input voltage of 2.5V. HO1, HO2, HO3 serve as high-side driver outputs, while LO1, LO2, LO3 are low-side driver outputs. To prevent cross-conduction, ensure proper synchronization of the input signals.

Connect the ITRIP pin to a current-sensing resistor to set the overcurrent protection threshold. CA- and CAO form an operational amplifier to monitor bridge current. The FAULT pin provides a signal for overcurrent or undervoltage lockout, which can be connected to external logic circuits for fault detection. Finally, carefully inspect the setup, power on the circuit, test its functionality, and fine-tune the parameters.
