IRS2113PBF Overview
A gate driver is a power-management IC that translates low-power logic-level PWM signals from a controller (such as a microcontroller, DSP, or motion ASIC) into high-current gate-drive signals capable of switching a power MOSFET or IGBT at high speed. In the EVICS taxonomy, the IRS2113PBF belongs to the gate driver -> power MOSFET/IGBT driver -> power management IC -> semiconductor hierarchy. Half-bridge gate drivers specifically produce two complementary outputs (HO and LO) with built-in dead-time/matching that drive the high-side switch and the low-side switch of a totem-pole power stage used in motor drives, inverters, and switching power supplies.
Key electrical specifications include a maximum offset supply voltage of 600 V, gate drive current capability of 2.5 A source and 2.5 A sink, an integrated shutdown (SD) pin, and 10 V to 20 V VCC operating range. The driver exhibits dV/dt immunity and tolerance to negative VS transients, which protects the high-side channel when the low-side switch pulls the switch node below ground during commutation. The IRS2113 variant differs from the IRS2110 family by adding the SD logic input.
Architecturally, the IRS2113PBF pairs a level-shifting high-side channel with a ground-referenced low-side channel. The high side is powered by an external bootstrap capacitor that is recharged every switching cycle through a low-side body-diode path, eliminating the need for an isolated DC supply. This bootstrap topology is what allows the chip to drive an N-channel MOSFET or IGBT on the high side of a 600 V bus from a single low-voltage VCC rail.
Typical applications include three-phase motor drives (HVAC compressors, industrial pumps, BLDC fans), solar microinverters and string inverters, switched-mode power supplies (SMPS), uninterruptible power supplies (UPS), and welding equipment. The SD input enables fast fault shutoff of both channels, which is useful in motor-control and Class-D audio amplifiers where the controller must disable outputs quickly during overcurrent events.
When designing with the IRS2113PBF, place the bootstrap capacitor (typically 0.1 uF to 1 uF ceramic) directly between VB and VS, and use a low-ESR VCC bypass (10 uF + 0.1 uF). The high-side return (VS) is a switching node that swings rapidly; keep the bootstrap loop compact to limit ringing and to avoid false triggering on dV/dt edges.

Typical Applications
IRS2113PBF is suitable for 6 applications: Three-Phase BLDC Motor Drive, Solar Microinverter, Switched-Mode Power Supply (SMPS), Uninterruptible Power Supply (UPS), Welding Equipment (Inverter Welder), Class-D Audio Amplifier Output Stage.
Three-Phase BLDC Motor Drive
The IRS2113PBF drives the three half-bridges of a BLDC or PMSM motor inverter from a single low-voltage VCC rail using its bootstrap topology. With 600 V Voffset and 2.5 A source/sink drive, it switches 600 V/600 V-class IGBTs at 20 kHz to 50 kHz PWM with controlled rise/fall times around 20 ns, limiting switching losses. The active-low SD input enables fast <130 ns overcurrent shutoff from a current-sense comparator, which is essential for industrial drive protection.
Recommended
Solar Microinverter
In a 600 V solar microinverter or string inverter the IRS2113PBF drives the primary-side half-bridge of the DC-AC stage. Its bootstrap high-side channel operates from a DC link up to 600 V, while 2.5 A source/sink current switches 600 V-class MOSFETs at >50 kHz to keep magnetics small. The SD pin enables fast PV arc-fault or overcurrent shutdown, meeting UL 1741 and NEC 2017 rapid-shutdown requirements.
Recommended
Switched-Mode Power Supply (SMPS)
In off-line SMPS half-bridge or full-bridge converters, the IRS2113PBF drives the primary-side 600 V MOSFETs from a 12-15 V VCC rail using bootstrap. Its 130 ns propagation delay and matched high/low side timing allow the LLC resonant converter to operate above 100 kHz with deterministic dead-time, while the SD pin is used for primary-side overcurrent latch-off. This driver replaces discrete pulse transformers in modern switch-mode designs.
Recommended
Uninterruptible Power Supply (UPS)
UPS systems use the IRS2113PBF to drive the half-bridge stages of their low-frequency isolation transformer and high-frequency DC-DC sections. The 600 V Voffset supports 230 V/400 V rectified bus rails; 2.5 A drive current handles IGBT modules up to 50 A collector current. The SD pin enables immediate inverter disable during battery overcurrent or short-circuit events, protecting both battery strings and downstream loads.
Recommended
Welding Equipment (Inverter Welder)
Inverter welders use the IRS2113PBF as the primary-side gate driver for the IGBT half-bridge switching the welding transformer at 20-50 kHz. The 600 V Voffset handles the rectified mains (typically 540 V DC), and 2.5 A drive current switches large planar IGBT modules. The SD input is wired to the current-sense transformer for fast arc-stick and overcurrent protection, which is critical for industrial welding safety standards.
Recommended
Class-D Audio Amplifier Output Stage
In high-power Class-D audio amplifiers the IRS2113PBF drives the 400 V half-bridge output stage switching at 250-500 kHz PWM. With 20 ns rise/fall times and matched propagation delays it keeps THD below 0.01%, while the SD input enables pop-free mute and DC-offset speaker protection. The 600 V rating supports +/-200 V audio swings from a 400 V bus, making it suitable for professional 1 kW+ PA amplifiers.

Key Differentiators
- Integrated active-low shutdown input (vs IRS2110PBF)

- Through-hole PDIP-14 for high-voltage clearance (vs IRS2113SPBF)
Design Notes
The IRS2113PBF draws its high-side Vb supply from a bootstrap capacitor (typically 0.1 uF to 1 uF ceramic) connected between VB (pin 10) and VS (pin 7). The bootstrap diode must be a fast-recovery type (UF4007 or better, <100 ns trr) and rated for at least 600 V to survive the rectified bus voltage. At 20 kHz with 2.5 A peak gate current, a 0.47 uF ceramic provides ~50 mV droop per PWM cycle.
Keep the high-side loop (HO - gate resistor - HS MOSFET gate - VS - return path to VB decoupling) physically compact - ideally under 1 square inch of loop area - to minimize parasitic inductance. The VS node switches at 600 V / 20 ns which can otherwise generate ringing >100 V. Place the bootstrap diode directly between VCC and VB with minimum trace length, and use a low-ESR VCC bypass (10 uF electrolytic + 0.1 uF ceramic) within 5 mm of the VCC pin.
The shutdown (SD) input is active-low and latched; tying it directly to VCC enables the driver, while leaving it floating disables both outputs. Do not tie SD to ground through a weak pull-down without verifying that the controller can release it; a stuck SD will prevent inverter startup. Also, when driving very high-current IGBT modules (>200 A), add a small gate-emitter resistor (10 kohm) to prevent parasitic turn-on from Miller coupling.
The IN input has Schmitt-trigger thresholds (typically 0.8 V low / 2.2 V high), making it compatible with both 3.3 V and 5 V logic without a level shifter. For noisy industrial environments, add a 1 nF ceramic filter on IN to prevent false triggering, and keep the IN trace short and away from the VS switching node. If using long IN traces (>25 mm), consider adding a 100 ohm series resistor to dampen ringing.
