Product details
Overview
98-0334PBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drivers for N-channel MOSFETs or IGBTs. It operates up to +600V on the floating high-side channels, supports 12–20V gate drive supply, features matched 250ns/180ns (typ.) propagation delays, undervoltage lockout per channel, and over-current shutdown via external sense resistor - used in industrial motor inverters and servo drives.
For engineers reviewing the 98-0334PBF datasheet, 98-0334PBF pinout, 98-0334PBF application, or 98-0334PBF equivalent, this page delivers verified technical context, real-world timing behavior, fault-clear RC network design guidance, and validated alternatives for 3-phase inverter gate driver selection.
Technical Context
The 98-0334PBF implements proprietary HVIC monolithic construction with level-shifted high-side drivers tolerant to −5V to +600V VS offset. Its shoot-through prevention logic enforces deadtime ≥220ns and cross-conduction avoidance across all six outputs.
It integrates independent UVLO thresholds (11.2V/11.0V for VCC/VBS), 3.3V logic-compatible inputs, open-drain FAULT output, and externally programmable fault-clear delay via RCIN (1.3–2ms typical). The ITRIP input has 4.3V threshold and 0.15V hysteresis for noise-immune current sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max VS offset | +600V - enables direct high-side drive of 600V-class power switches without external level shifters |
| ton / toff (typ.) | 250ns / 180ns - supports >1MHz PWM switching with tight timing control in servo and BLDC inverters |
| VCC supply range | 12–20V - compatible with standard 15V auxiliary rails; UVLO at 11.2V ensures robust startup under brownout |
| ITRIP threshold | 4.3V ±0.45V - interfaces directly with 4V-referenced current-sense amplifiers, eliminating level-shifting circuitry |
| Input logic compatibility | 3.3V CMOS/LSTTL - allows direct connection to FPGA, MCU, or DSP GPIO without level translators |
| FAULT output type | Open-drain - enables wired-OR fault bus implementation across multi-driver systems |
| RCIN fault clear time | 1.3–2ms (R=2MΩ, C=1nF) - provides adjustable recovery window after overcurrent events |
Pinout & Package
98-0334PBF is packaged in a 28-lead SOIC (Small Outline Integrated Circuit) with exposed thermal pad, optimized for surface-mount assembly and thermal dissipation in motor drive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply input | 12–20V fixed rail powering internal logic, level shifters, and low-side drivers |
| VSS | Logic ground reference | Common return for all digital inputs and internal biasing; isolated from power ground COM |
| COM | Power ground reference | Return path for LOx outputs and current-sense circuitry; tied to system power ground |
| HIN1–3 / LIN1–3 | High-side and low-side PWM inputs | 3.3V-compatible logic inputs; HINx inverted relative to LINx for IR21363/IR21365 variants |
| HO1–3 / LO1–3 | High-side and low-side gate drive outputs | Capable of ±200mA pulsed sink/source; HOx referenced to VSx, LOx referenced to COM |
| VS1–3 | High-side floating source monitor | Each monitors respective high-side switch source node; withstands −5V to +600V transients |
| VB1–3 | High-side bootstrap supply input | Accepts 12–20V floating supply per channel; UVLO at 11.0V prevents erratic high-side turn-on |
| ITRIP | Over-current trip input | 4.3V threshold with 0.15V hysteresis; triggers simultaneous shutdown of all six outputs |
| EN | Global enable input | Active-high; forces all outputs low when pulled low; 3.0V VIH threshold ensures noise margin |
| FAULT | Open-drain fault indicator | Pulled low during UVLO or overcurrent; high-impedance otherwise; supports shared fault bus |
| RCIN | Fault auto-clear timing input | RC network sets recovery delay (1.3–2ms); internal comparator triggers FAULT release above 8V |
Key Features
| Feature | Design Value |
|---|---|
| Matched propagation delay | ≤70ns max mismatch between any two channels - eliminates phase skew in 3-phase PWM timing |
| Cross-conduction prevention logic | Hardware-enforced deadtime ≥220ns - prevents shoot-through without software timing overhead |
| Externally programmable fault clear | RCIN pin accepts R-C network (e.g., 2MΩ + 1nF) to set precise 1.3–2ms recovery window |
| dV/dt immune floating channel | Withstands 50V/ns transient slew rates on VS pins - maintains reliable operation in noisy inverter environments |
| Lower di/dt gate driver | Reduced edge rate minimizes EMI generation and improves noise immunity in compact motor drive layouts |
Applications
| Industrial Motor Inverters | BLDC Motor Drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR21363PbF | Same 250ns/180ns propagation, but 0.46V ITRIP threshold and 11.2V/11.0V UVLO - optimized for low-side current sensing | Requires shunt-based current sensing below power switches; less suitable for high-side sense topologies | Select when using low-side shunt + op-amp with 0.5V full-scale output |
| IR21366PbF | Identical timing and package, but 2.0V/1.3V VIH/VIL and 0.46V ITRIP - lower logic threshold improves noise margin in high-noise environments | Better suited for industrial settings with long traces or unshielded harnesses near motors | Prefer for designs with >10cm trace lengths between MCU and driver, or where EFT immunity is critical |
Compared with IR21363PbF and IR21366PbF, 98-0334PBF offers identical timing performance and SOIC-28 packaging but uses a 4.3V ITRIP threshold that simplifies interface to 4V-referenced current-sense amplifiers - reducing component count in mid-range motor drives.

FAQ
What is the maximum allowable dV/dt on the VS pins?
The 98-0334PBF is rated for 50 V/ns dV/dt on VS1–3 pins. This specification ensures reliable level-shifting operation during fast-switching transients in 600V inverter legs. Exceeding this rate may cause false triggering or latch-up; layout best practices (short traces, local decoupling, ground plane integrity) must be followed to maintain margin.
How does the RCIN pin control fault recovery timing?
The RCIN pin connects to an external R-C network (e.g., 2 MΩ + 1 nF) that charges toward VCC. When voltage exceeds 8 V, the internal comparator releases the FAULT latch, restoring normal operation after 1.3–2 ms. This allows precise, hardware-controlled recovery without MCU intervention - critical for safety-critical motor restarts.
Can the 98-0334PBF drive both MOSFETs and IGBTs?
Yes - the 98-0334PBF's ±200mA/±350mA peak output current and 12–20V gate drive range support both N-channel MOSFETs (e.g., IPW65R045CP) and 600V IGBTs (e.g., IKW40N60T). Its 250ns/180ns propagation delays and low di/dt drivers minimize switching losses and EMI in either topology.
Is there a difference between HIN and LIN polarity behavior across IR2136x variants?
Yes - for 98-0334PBF (IR21363/IR21365 derivative), HIN1–3 outputs are inverted relative to LIN1–3, enabling complementary drive without external inverters. This differs from IR21362 (non-inverted HIN) and IR21366/IR21367 (inverted HIN with lower VIH/VIL), confirmed by functional block diagrams and timing tables in PD60166 revS.
