IR2132STRPBF Overview
A three-phase gate driver IC belongs to the broader category of gate drivers within the power management and motor-control semiconductor family. Gate drivers sit between low-power control logic (such as a microcontroller PWM output) and the high-power discrete switches (IGBTs or power MOSFETs) that actually commutate current in a motor or inverter. The three-phase topology specifically targets brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) drives, where six switches arranged in three half-bridges must be sequenced 120 electrical degrees apart. By integrating six gate-drive channels plus protection and an op-amp onto a single high-voltage die, the IR2132STRPBF eliminates dozens of discrete components and shrinks the inverter footprint.
Key features include floating-channel bootstrap architecture that allows the high-side drivers to operate up to 600 V without an isolated supply, undervoltage lockout (UVLO) on all six channels that protects the power stage from insufficient gate-drive voltage, a current-sense op-amp that conditions shunt-resistor feedback for over-current protection, and a FAULT output that latches during a desaturation or OC event. The dead-time is internally fixed at approximately 0.8 Β΅s to prevent shoot-through in the half-bridge. The 28-SOICWB package exposes a thermal pad for improved heat dissipation during continuous switching.
Typical applications span industrial variable-frequency drives (VFDs), BLDC/PMSM motor controllers for appliances and pumps, uninterruptible power supplies (UPS), solar micro-inverters, and three-phase AC induction drives. With the global push toward electrification in HVAC, e-mobility, and factory automation, the IR2132STRPBF remains a workhorse part in the 600 V class.
When designing with the IR2132STRPBF, observe the bootstrap-capacitor sizing rule that the bootstrap cap must recharge the high-side supply within every switching cycle - typically a 1 Β΅F or larger ceramic is required for motor-PWM frequencies above 15 kHz. Place the VSS bypass capacitor directly between the VSO pin and the COM pin to keep the current-sense path quiet, and keep the OC-trip filter network close to the ITRIP pin to avoid false triggering from switching noise.

Typical Applications
IR2132STRPBF is suitable for 6 applications: Industrial Variable-Frequency Drives (VFD), BLDC / PMSM Motor Controller, Uninterruptible Power Supplies (UPS), Solar String Inverters, Three-Phase AC Induction Motor Drives, Home Appliance Motor Inverters.
Industrial Variable-Frequency Drives (VFD)
The IR2132STRPBF fits 200 V to 480 V three-phase VFDs because its 600 V offset rating covers the rectified 380/480 V AC bus with margin, while its integrated op-amp conditions the shunt-resistor feedback for FOC firmware running on a DSP/MCU. The 0.25 A/0.5 A source/sink current can drive 25 A-class IGBT modules at up to 20 kHz PWM, and the FAULT output enables hardware desaturation protection that is mandatory in IEC 61800-5-1 safety architectures.
Recommended
BLDC / PMSM Motor Controller
The IR2132STRPBF drives the six switches of a 3-phase BLDC or PMSM inverter for appliances, e-bikes, drones, and pumps. Its 600 V rating covers 48 V to 220 V battery-fed motors, while the integrated current-sense op-amp directly feeds an ADC for sensorless FOC. The latched FAULT output protects against rotor-lockup over-current events by latching all six gate outputs low, satisfying functional-safety requirements without external logic.
Recommended
Uninterruptible Power Supplies (UPS)
The IR2132STRPBF drives the inverter stage of online and line-interactive UPS systems rated 1 kW to 10 kW. Its 600 V offset handles the 400 V DC bus from a power-factor-corrected front end, while the ITRIP comparator provides sub-microsecond shutdown on output short-circuit conditions. The internal op-amp amplifies the DC-link current shunt for battery-discharge regulation loops, and the wide 10 V to 20 V VCC range simplifies powering from either 12 V or 15 V auxiliary rails.
Recommended
Solar String Inverters
The IR2132STRPBF is used in 600 V-class solar string inverters where three-phase transformerless topologies require dV/dt-tolerant floating high-side drivers. Its 0.5 A sink current ensures fast turn-off of the IGBTs, limiting switching losses at high solar-input voltages, while the negative transient tolerance handles the inductive ringing common to long-string cable harnesses. The integrated FAULT and ITRIP enables the rapid shutdown required by NEC 2017 / UL 1741 for grid-tie PV systems.
Recommended
Three-Phase AC Induction Motor Drives
The IR2132STRPBF is a strong fit for general-purpose 230 V / 400 V AC induction motor drives used in HVAC compressors, conveyor belts, and machine tools. Its 600 V rating covers the rectified 400 V DC bus with derating headroom, and the 675 ns propagation delay supports V/f scalar control at switching frequencies up to 25 kHz. The integrated OC protection eliminates the need for an external comparator, reducing BOM cost and PCB area in cost-sensitive industrial designs.
Recommended
Home Appliance Motor Inverters
The IR2132STRPBF fits inverterized washing-machine drum motors, refrigerator compressors, and air-conditioner outdoor fans where a 200 V to 220 V three-phase inverter drives the BLDC compressor. Its small 28-SOICWB footprint and integrated OC/FAULT reduce the BOM count by 15+ components versus discrete solutions. The 600 V rating future-proofs designs migrating from 120 V to 240 V markets, and the integrated op-amp supports single-shunt FOC for silent, energy-efficient operation meeting EU EcoDesign 2021 standards.

Design Notes
Bootstrap capacitor sizing is critical for the IR2132STRPBF high-side channels. Each high-side driver draws charge from its bootstrap capacitor (CB) during switching cycles, and CB must recharge fully during the low-side ON-time. A common rule of thumb is CB >= 10 * Qg_of_high_side_FET, with a typical 1 Β΅F X7R ceramic (rated 25 V or higher) for Qg up to 50 nC. If your PWM duty cycle is >95% on the high-side (rare, but possible in some PFC topologies), add a separate bootstrap refresh circuit or increase CB to 4.7 Β΅F. Bootstrap diode selection should use ultrafast (trr < 100 ns) 1 A rectifiers such as UF4007 for low cost, or low-Cj Schottky diodes (e.g., MBRS140) for lowest losses at high frequency.
Use a 4-layer PCB with a continuous ground plane under the IR2132STRPBF and the three high-side return traces (VS1/VS2/VS3). Keep the VCC decoupling capacitor within 5 mm of the VCC pin and the COM/VSS bypass within 5 mm of the COM pin; the ITRIP filter RC network must also be close to the ITRIP pin to avoid false triggering. The exposed pad of the 28-SOICWB package must be soldered to a copper pour of at least 1 sq inch with thermal vias (0.3 mm diameter, 1 mm pitch) to the inner ground plane for heat dissipation. Avoid running digital signal traces (PWM inputs from MCU) directly under the high-voltage VS node traces to prevent capacitive crosstalk.
Common design pitfalls with the IR2132STRPBF include: (1) forgetting that input logic is inverting - a logic LOW on HIN/LIN turns the gate ON, which catches engineers coming from non-inverting drivers like the IRS26302; (2) underrating the bootstrap capacitor for high-side ON-time beyond 90% duty cycle, which causes VS undervoltage and spurious fault trips; (3) leaving ITRIP floating - if unused, tie it to VCC through a 100 kΞ© resistor to prevent random triggering from PCB leakage; (4) using a slow diode (>500 ns trr) for bootstrap, which causes voltage droop and high-side UVLO at switching frequencies above 15 kHz; (5) neglecting the negative VS transient tolerance rating and adding clamping diodes that fight the dV/dt immunity of the part.
