IRS2005MTRPBF Overview
What is a half-bridge gate driver? A gate driver is a power amplifier that translates low-power control signals from a microcontroller or PWM controller into the high-current, high-voltage drive signals required to switch power transistors (MOSFETs, IGBTs, GaN HEMTs). In the half-bridge topology, two transistors form a series connection between a DC bus and ground, and the gate driver controls both the high-side and low-side transistors with proper dead-time and level shifting. The high-side drive demands a bootstrap supply architecture, and the driver IC handles this internally to provide a floating high-side return.
Key features of the IRS2005MTRPBF include VCC and VBS under-voltage lockout (UVLO) for safe startup, a typical 0.29A source current capable of driving small IGBTs and MOSFETs, and 0.6A sink current for fast turn-off. The 200V voltage rating supports 120V AC-rectified bus voltages commonly found in offline motor drives and induction cookers. The non-inverting input logic simplifies microcontroller interface design.
Architecturally, the IRS2005MTRPBF integrates a level shifter, bootstrap diode for the high-side supply, gate drive buffers for both outputs, and independent UVLO comparators for VCC (low-side supply) and VBS (high-side bootstrap supply). The exposed thermal pad of the MLPQ-14 package provides a low thermal resistance path to PCB copper.
Typical applications include variable-frequency drives (VFD), HVAC motor controllers, industrial fans and pumps, half-bridge and full-bridge converters, electronic ballasts for HID and fluorescent lighting, induction heating, and Class D audio amplifiers. The 200V rating is well matched to 120VAC single-phase rectified buses.
When designing with this part, place the bootstrap capacitor (typically 1uF ceramic) close to the VB and VS pins, and ensure the high-side return (VS) is connected directly to the source of the high-side MOSFET. The exposed pad must be soldered to a sufficient copper pour for thermal dissipation, especially at higher switching frequencies.

Typical Applications
IRS2005MTRPBF is suitable for 6 applications: Variable-Frequency Motor Drives (VFD), Electronic Ballasts for Lighting, Half-Bridge and Full-Bridge DC-DC Converters, Class D Audio Amplifiers, Induction Heating Cooktops, Solar Micro-Inverters and Power Optimizers.
Variable-Frequency Motor Drives (VFD)
The IRS2005MTRPBF is well suited for variable-frequency drives controlling small AC induction motors and BLDC motors in industrial applications. Its 200V maximum offset voltage comfortably covers 120VAC single-phase rectified bus voltages (peak approximately 170V), while the 0.29A source and 0.6A sink currents drive IGBTs with Qg up to approximately 30nC at 20kHz switching frequency. The integrated bootstrap diode eliminates an external component, simplifying PCB layout in motor control modules. VCC and VBS UVLO protect the power stage during supply startup and brownout events.
Recommended
Electronic Ballasts for Lighting
Electronic ballasts for HID, fluorescent, and UV-C germicidal lamps use half-bridge resonant inverters as their power stage. The IRS2005MTRPBF provides the high-side and low-side gate drive for these inverters, with 200V rating matching the rectified mains voltage of 120VAC systems. The 0.6A sink current ensures rapid turn-off to minimize switching losses in the resonant tank. Integrated UVLO on both VCC and VBS prevents the ballast from operating in unsafe modes during lamp warm-up or removal, a critical safety feature for lighting applications.
Recommended
Half-Bridge and Full-Bridge DC-DC Converters
Half-bridge and full-bridge DC-DC converter topologies use the IRS2005MTRPBF to drive the primary-side switches of isolated power supplies up to 200V input. The non-inverting input logic accepts PWM signals directly from a digital controller, and the integrated bootstrap supply reduces external component count. For 200W-class converters operating at 100kHz, the 0.29A source current drives MOSFETs with Qg in the 15-25nC range, enabling compact telecom and industrial power supply designs. The MLPQ-14 exposed pad provides thermal relief for the continuous switching losses.
Recommended
Class D Audio Amplifiers
Class D audio amplifiers use half-bridge or full-bridge output stages to achieve high efficiency, and the IRS2005MTRPBF provides the gate drive for the output MOSFETs. The 200V rating supports higher-power amplifiers with 100V bus rails, while the fast 0.6A sink current minimizes dead-time and reduces output distortion. The integrated bootstrap supply simplifies the BTL (bridge-tied load) output stage design. For subwoofer and professional audio amplifiers, the IRS2005MTRPBF enables compact PCB layouts while maintaining the audio signal fidelity required for high-quality sound reproduction.
Recommended
Induction Heating Cooktops
Induction cooktops use resonant half-bridge or full-bridge inverters to drive the induction coil, and the IRS2005MTRPBF provides the high-side and low-side gate drive for the IGBTs in this topology. The 200V rating matches the rectified 120VAC mains supply, while the 0.6A sink current ensures fast IGBT turn-off to minimize switching losses in the high-frequency resonant tank. UVLO protection prevents the cooktop from operating during supply voltage sags that could cause unsafe IGBT operation. The MLPQ-14 exposed-pad package enables compact PCB layouts in space-constrained cooktop designs.
Recommended
Solar Micro-Inverters and Power Optimizers
Small solar micro-inverters and module-level power optimizers use half-bridge or full-bridge topologies to convert PV panel DC output to AC grid or optimized DC. The IRS2005MTRPBF drives the primary-side switches in these compact converters, with the 200V rating suitable for residential 120V grid-tie applications. The integrated bootstrap supply reduces BOM cost and PCB area, both critical for the small-form-factor micro-inverter enclosure. The MLPQ-14 package's exposed pad provides the thermal performance needed for continuous operation at elevated ambient temperatures on rooftops.

Design Notes
Place the bootstrap capacitor (typically 1uF ceramic, X7R) as close as possible between the VB and VS pins to minimize parasitic inductance. The high-side gate drive loop (VB-HO-VS path) must be kept small, with the capacitor traces short and direct. The exposed thermal pad must be soldered to a sufficient copper pour (minimum 100mm^2) to keep junction temperature within ratings.
The VCC supply for the low-side driver should be decoupled with a 0.1uF ceramic capacitor close to the VCC pin, plus a bulk capacitor (4.7uF to 10uF) at the IC supply pin. The bootstrap capacitor value must be sized to provide sufficient charge for the gate drive pulses without excessive voltage droop. For continuous switching at high frequency, consider 2.2uF or larger to minimize ripple on the high-side supply.
Do not exceed the 200V maximum offset voltage between the high-side output (HO) and the VS pin. Ensure VS is connected directly to the source of the high-side MOSFET - any stray inductance in this path can cause voltage spikes that exceed the driver's maximum rating. During PCB layout, minimize the loop area of the high-side switching node to reduce EMI and voltage stress on the driver IC.
The MLPQ-14 exposed pad provides the primary thermal dissipation path. Estimate: at 100kHz switching frequency with 20nC gate charge MOSFETs, gate drive losses are approximately 40mW per channel (P = Qg x Vgs x fsw). The MLPQ-14 theta_JA is typically 40 C/W on a standard JEDEC test board, giving a junction temperature rise of less than 2C - well within thermal limits for most applications.
