Pin Function Specifications
Here’s a detailed breakdown of the 14 pins of the IR2113 driver IC. This is for a 14-pin DIP package, but the functions apply similarly to other package types.
Pin Number Pin Name Pin Function Description 1 VSS Ground Pin: This pin connects to the system ground for the IC. 2 VB Bootstrap Pin: This is the bootstrap pin for the high-side driver. It requires a capacitor to be connected between VB and VS to provide a stable voltage for the high-side MOSFET driver. 3 VS High-Side Source Pin: This pin connects to the source of the high-side MOSFET (or IGBT). This voltage varies with the switching of the MOSFETs. 4 HO High-Side Output: This pin connects to the gate of the high-side MOSFET (or IGBT). The voltage here drives the high-side MOSFET. 5 COM Common Pin: This is the reference ground for the low-side driver and the logic circuit. 6 LO Low-Side Output: This pin connects to the gate of the low-side MOSFET (or IGBT). The voltage here drives the low-side MOSFET. 7 VSS Ground Pin: Ground reference for low-side driver. 8 NC No Connect: This pin is not connected to any internal circuitry and is typically unused in the circuit. 9 HIN High-Side Input: This pin receives the input signal for driving the high-side MOSFET gate. 10 LIN Low-Side Input: This pin receives the input signal for driving the low-side MOSFET gate. 11 VCC Low-Side Positive Supply Pin: This pin connects to the low-side power supply (typically 10-20V) for the low-side driver. 12 VSS Ground Pin: Ground for low-side circuit. 13 HO High-Side Output: The output driving the high-side MOSFET (or IGBT). 14 VB Bootstrap Pin: This is the bootstrap pin that drives the high-side MOSFET. It’s necessary for the high-side MOSFET switching when configured.Package Type and Pin Configuration
