2EDN7533RXTMA1 - Dual 5A Low-Side Gate Driver | Infineon
The Infineon 2EDN7533RXTMA1 is a dual-channel, low-side gate driver IC delivering up to 5 A peak source/sink current from a compact PG-TSSOP-8 (HTSSOP) package. It features two independent inverting driver channels with 1.3 ns typical channel-to-channel delay matching and under-voltage lockout (UVLO) protection per channel. The driver targets high-frequency power conversion in synchronous rectification, telecom DC-DC bricks, and Class-D audio stages. A low-side gate driver is a power-management IC that switches the gate of a low-side MOSFET or IGBT to ground, controlling its turn-on and turn-off from a low-voltage logic signal (typically 3.3 V or 5 V PWM). Within the system hierarchy, gate drivers sit between the controller IC (microcontroller, DSP, or PFC controller) and the power MOSFETs, providing the high peak currents needed to charge and discharge gate capacitances quickly. Low-side drivers in particular manage the lower switch in a half-bridge or the flyback/forward return switch, where the source/emitter is referenced to system ground. The 2EDN family from Infineon's EiceDRIVER portfolio is engineered for very low propagation delay, enabling hard-switched topologies up to several hundred kHz. Key specifications include 5 A peak output current with 0.5 ohm typical output resistance (pull-up) and 0.3 ohm pull-down, 19 ns typical propagation delay, and an absolute maximum VDD of 25 V (recommended 4.5 V to 20 V). The device operates across -40 C to +150 C junction temperature and accepts LV-TTL logic inputs that tolerate -12 V to +22 V transients. The -R suffix in 2EDN7533R indicates inverting input polarity. Architecturally, the 2EDN7533R uses matched CMOS output stages with independent UVLO comparators per channel, ensuring one rail can be brought up before the other without latch-up. The integrated bootstrap-free design (low-side only) simplifies PCB layout and eliminates the high-side level-shift losses found in half-bridge drivers. Typical applications include synchronous-rectifier MOSFET driving in telecom and server DC-DC converters, Class-D audio amplifier output stages, motor-drive low-side switches, and high-frequency point-of-load (POL) converters. The dual independent channels also fit OR-ing FET control, low-side switches in digitally-controlled power, and housekeeping load switches. When designing with this part, place the 100 nF VDD bypass capacitor within 2 mm of the IC and keep the gate-drive loop area below 0.5 cm to control ringing. The dual inverting topology requires non-overlap timing to be enforced by the controller; the 2EDN7533R itself does not include built-in dead-time generation.
2EDN7534FXTMA1 - Dual 5A Low-Side Gate Driver DSO-8 | Infineon
The Infineon 2EDN7534FXTMA1 is a dual-channel low-side 5 A gate driver IC designed for high-speed switching of MOSFETs and wide-bandgap (WBG) power switches such as GaN and SiC devices, housed in an 8-pin PG-DSO package. It delivers 5 A peak source/sink output current with typical 19 ns propagation delay and active output voltage clamping to VDD, making it well-suited for telecom, server, and industrial SMPS applications. What is a gate driver IC? A gate driver is a power amplifier that accepts a low-current logic-level PWM signal from a microcontroller, FPGA, or dedicated controller IC and produces a high-current drive signal capable of rapidly charging and discharging the gate capacitance of a power MOSFET, IGBT, or WBG switch. Gate drivers sit between the control domain (digital logic) and the power domain (switching transistors), enabling clean, fast switching transitions that minimize switching losses and reduce dead time. As a low-side driver, the 2EDN7534F controls the source-referenced switch in a half-bridge or low-side power stage. Key differentiating features of the 2EDN7534F include independent dual channels for parallel or synchronous drive, an enable input for sequenced startup, LV-TTL compatible logic inputs that tolerate -12 V to +22 V, and an absolute maximum supply of 20 V. Its active output clamping structure prevents gate voltage overshoot, which is critical when driving GaN HEMTs sensitive to Vgs transients. Tight matched-channel timing (typically <1 ns channel-to-channel skew) supports precision synchronous rectification. Architecturally, the device uses a complementary CMOS output stage with integrated bootstrap-style pull-up/pull-down devices sized for nanosecond-class rise/fall times. The 19 ns typical propagation delay and sub-nanosecond jitter preserve PWM edge fidelity in high-frequency designs up to several MHz. Built-in under-voltage lockout (UVLO) protects against insufficient gate-drive voltage during power-up and brown-out conditions. Typical applications include telecom 48 V bus converters, server and datacom point-of-load stages, synchronous buck and forward converter low-side switches, Class-D audio amplifier output stages, and motor drive low-side FETs in industrial automation. Designers favor this part where multiple parallel low-side MOSFETs require matched, high-current drive. When designing with the 2EDN7534F, keep the gate-drive loop (driver output to gate to source back to driver ground) as short and wide as possible to minimize parasitic inductance that can otherwise cause ringing and EMI. Place the VDD bypass capacitor directly at the IC supply pin with a 100 nF ceramic in parallel with a 1 µF bulk capacitor.

2EDN7534RXTMA1 - Dual 5A Low-Side Gate Driver | Infineon | PG-TSSOP-8
The Infineon 2EDN7534RXTMA1 is a dual-channel low-side gate driver IC delivering up to 5 A peak source/sink current per channel in a compact PG-TSSOP-8 package. It features low on-resistance output stages and excellent timing accuracy for driving power MOSFETs, IGBTs, and especially wide-bandgap (WBG) devices such as GaN HEMTs and SiC MOSFETs that demand fast, clean gate edges. The device is part of Infineon's EiceDRIVER 2EDN family and is specified for operation from 4.5 V to 20 V supply voltage. A low-side gate driver is a critical signal-level interface that translates a 3.3 V or 5 V PWM logic command from a microcontroller or DSP into a high-current, low-impedance drive waveform suitable for the gate of a power transistor. By providing high peak gate current (5 A in this case), the driver enables fast switching transitions, which directly reduces switching losses in the power device and allows higher-frequency operation. Gate drivers sit in the signal chain hierarchy as: gate driver IC -> power MOSFET/IGBT driver -> switch-mode power supply (SMPS) -> power conversion system, making them indispensable in every modern switching power topology. Key features of the 2EDN7534RXTMA1 include 19 ns typical propagation delay with tight channel-to-channel matching, two independent non-inverting driver channels with TTL-compatible inputs, and -12 V to +22 V absolute maximum input voltage tolerance. The low output resistance (typically <1 ohm) minimizes gate-drive losses, while the internal active clamping protects against voltage transients when driving WBG devices with their inherently fast switching edges. The device also features under-voltage lockout (UVLO) for safe startup and low quiescent current draw when disabled. Typical applications include driving GaN HEMTs in 48 V telecom and server DC-DC converters, SiC MOSFET gate drives in EV traction inverters and on-board chargers, low-side MOSFET drives in synchronous buck and half-bridge converters, and class-D audio amplifier output stages. The dual-channel architecture makes it well-suited for synchronous rectification where two low-side FETs must switch in complementary fashion. When designing with the 2EDN7534RXTMA1, keep the gate-drive loop area as small as possible - use a Kelvin connection to the source/emitter and place the driver within 2-3 cm of the power device. Use a 1 uF ceramic bypass capacitor close to VCC and a 4.7-10 uF bulk capacitor on the driver supply rail. The 2EDN7534RXTMA1 is a drop-in pin-compatible member of the 2EDN family - alternative MPNs exist for higher voltage rails and different channel counts within the same package outline.

2EDN8533RXTMA1 - Dual 5A Low-Side Gate Driver IC | Infineon
The Infineon 2EDN8533RXTMA1 is a dual-channel low-side gate driver IC delivering 5 A peak source/sink current in a PG-TSSOP-8 package with an exposed thermal pad. It is part of Infineon's EiceDRIVER 2EDN family and is specified for driving power MOSFETs, IGBTs, and GaN switches in switching power applications where compact footprint and fast switching transitions are critical. Two independent channels in one package enable half-bridge drive with external bootstrap, synchronous buck high-side drive, or dual low-side drive topologies. A low-side gate driver IC is an integrated circuit that sits between a low-voltage logic-level control signal (typically 3.3 V PWM from a microcontroller or PWM controller) and the gate of a power switching transistor (MOSFET, IGBT, or GaN HEMT). Its role is to translate the weak control signal into a strong, high-peak-current drive that can rapidly charge and discharge the transistor's gate capacitance, minimising switching losses and dead-time. In the broader power-management hierarchy, a gate driver sits between a PWM controller IC (e.g., a buck or LLC controller) and the power stage, and is itself a category of power MOSFET driver under PMIC functions. Key features of the 2EDN8533RXTMA1 include 5 A peak source/sink output current per channel, low output resistance for fast switching edges, excellent timing accuracy with tightly matched propagation delays between channels, and TTL-compatible inputs that can withstand absolute maximum voltages from -12 V to +22 V. The device operates over a wide VCC range and includes under-voltage lockout (UVLO) protection on the supply rail to prevent the driven transistor from operating in its linear region during low-VCC conditions, which would otherwise cause dangerous shoot-through or excessive dissipation. The 2EDN8533RXTMA1 uses a matched-die dual-channel architecture in a small 8-pin PG-TSSOP package with an exposed pad that provides both a low-impedance ground return and a thermal path for sustained switching current. Each channel can drive MOSFETs in several-hundred-kHz to low-MHz switching applications, making the IC suitable for high-density DC-DC converters and synchronous rectification stages. The wide input-voltage tolerance simplifies interface to 3.3 V or 5 V logic without external level shifters or protection Zener diodes. Typical applications include DC-DC buck and boost converter power stages, synchronous rectifier drivers, half-bridge and full-bridge driver stages when paired with a high-side bootstrap driver, motor drive low-side gate stages, Class-D audio amplifier output stages, and telecom/server point-of-load converters. The PG-TSSOP-8 footprint keeps the driver close to the power transistors, minimising parasitic loop inductance that would otherwise slow switching edges and cause ringing or voltage overshoot. When designing with the 2EDN8533RXTMA1, place input and bypass capacitors as close to VCC and GND pins as possible and connect the exposed pad to a solid ground plane to minimise parasitic inductance. The wide input tolerance allows direct connection to 3.3 V or 5 V logic, but designers should still respect absolute maximum ratings. For half-bridge work, the device is typically paired with a high-side bootstrap driver such as Infineon's 2ED2106S06J or the IR2110 family to complete a complete bridge drive solution.

2EDN8534FXTMA1 - 5A Dual Low-Side Gate Driver | Infineon
The Infineon 2EDN8534FXTMA1 is a dual-channel 5 A low-side gate driver IC for MOSFETs and wide-bandgap (WBG) switches, featuring 19 ns propagation delay and active output voltage clamping, housed in an 8-pin PG-DSO-8 (DSO-8) package. The IC provides two independent non-inverting driver channels capable of sinking and sourcing 5 A peak gate current, enabling fast switching of power MOSFETs, GaN HEMTs, and SiC devices in switching-converter and motor-drive applications. A gate driver is a power-management IC that sits between a low-current control stage (microcontroller, FPGA, isolator) and the gate of a power transistor. Because the gate of a power MOSFET effectively appears as a large nonlinear capacitor (often several nF), the driver must supply and remove charge quickly to achieve low switching loss. Low-side drivers reference the source/emitter of the switch to the system ground and only need to swing the gate between ground and the gate-drive supply, making them the simplest, lowest-cost gate-drive topology. Within the broader taxonomy, the 2EDN8534 belongs to gate driver ICs, which sit under power management ICs and are essential building blocks of every switched-mode power supply, motor drive, and Class-D amplifier. The "EiceDRIVER" brand denotes Infineon's gate-driver product family. Key features include 4.5 V to 20 V supply voltage range, 5 A peak source/sink output current, 19 ns typical propagation delay, 1 ns channel-to-channel delay matching, and a Miller-clamp transistor for active gate-voltage clamping. The non-inverting inputs are LV-TTL compatible and tolerate absolute maximum input voltages from -12 V to +22 V, simplifying interface with microcontroller GPIO and digital isolators. Internal under-voltage lockout (UVLO) protects the power stage from insufficient gate drive. The DSO-8 package offers a thermal-resistance performance adequate for continuous switching at moderate frequencies. The EiceDRIVER 2EDN family uses a matched dual-channel architecture that minimizes timing skew between channels, critical for synchronous rectifiers and half-bridge low-side drive where channel mismatch would cause body-diode conduction losses. Compared to discrete push-pull driver pairs, the 2EDN8534F provides tighter delay matching, lower quiescent current, and integrated active Miller clamping that prevents parasitic turn-on of the complementary device in half-bridge topologies. Typical applications include DC-DC converter synchronous rectification, telecom brick and POL converter gate drive, Class-D audio amplifier output stage drive, motor-driver low-side drive, and industrial SMPS. The wide input-voltage tolerance and active Miller clamp make it especially well suited to high-frequency, hard-switched converters using GaN or SiC devices. When designing with this device, place input and output bypass capacitors as close as possible to the IC and keep gate-drive loops small to minimize parasitic inductance. The 5 A peak drive capability enables switching of large power MOSFETs at high dV/dt, so PCB layout must control ground bounce and avoid noise coupling back into the input pins.

2EDR7259XXUMA1 - 5A/9A Isolated Gate Driver 5700Vrms | Infineon
The Infineon 2EDR7259XXUMA1 is an isolated dual-channel gate driver with 5 A typical source and 9 A peak sink drive current, 5700 Vrms galvanic isolation, and 150 V/ns common-mode transient immunity (CMTI) in a PG-DSO-14 narrow-body package. It is engineered for driving the high-side and low-side MOSFETs or IGBTs of half-bridge and full-bridge power stages in switched-mode power supplies (SMPS), motor drives, and industrial inverter blocks where reinforced isolation between the low-voltage control domain and the high-voltage power domain is mandatory. Key features include 38 ns typical propagation delay with tight channel-to-channel matching, integrated undervoltage lockout (UVLO) for both driver rails, and functional isolation reinforcement per IEC 60747-17/VDE 0884-11. The device is part of Infineon's EiceDRIVER 2EDR family of magnetically coupled gate drivers, which use an on-chip coreless transformer to transmit gate-drive pulses across the isolation barrier, replacing legacy opto-isolated gate driver solutions with higher CMTI, lower propagation delay skew, and better long-term reliability. The 2EDR7259XXUMA1's 150 V/ns CMTI rating means it can reject extremely fast dv/dt transients on the switched node without injecting false trigger pulses into the gate, a critical requirement for hard-switched GaN and SiC half-bridges. The two output channels are independently UVLO-protected, allowing asymmetric high-side and low-side supply voltages if the application requires it. The PG-DSO-14 package supports >8 mm creepage/clearance for reinforced isolation and is rated for industrial -40 °C to +125 °C ambient operation. Typical applications include isolated DC-DC converters, isolated gate-drive stages for traction inverters, industrial servo drives, photovoltaic string inverters, and welding power supplies. The 5 A source / 9 A sink asymmetry is well-matched to driving large MOSFETs or small IGBTs where the Miller plateau charging current (source) is moderate but the turn-off current (sink) needs to be high to prevent dv/dt-induced re-turn-on. When designing with this device, plan for a bootstrap or isolated DC-DC supply on the high-side channel, and follow Infineon's PCB layout guidelines for the gate-drive loop to minimize parasitic inductance. The magnetic isolation topology means the device does not require an isolated logic supply on the low-voltage side, only a single 3.3 V or 5 V VCC rail.

2EDR8258XXUMA1 - 5A/9A Isolated Gate Driver, 5.7kV | Infineon
The Infineon 2EDR8258XXUMA1 is a 5 A source / 9 A sink reinforced isolated single-channel gate driver with 5.7 kVrms galvanic isolation, housed in a 14-pin PG-DSO package with 150 V/ns common-mode transient immunity (CMTI) and 38 ns typical propagation delay. It uses Infineon's coreless transformer (CT) isolation technology to drive the gates of IGBTs, MOSFETs, and SiC power switches in half-bridge and high-side/low-side topologies. An isolated gate driver is a semiconductor device that provides both level shifting and galvanic isolation between a low-voltage control circuit (such as a microcontroller or PWM controller) and the gate of a high-voltage power transistor. Isolated gate drivers belong to the broader category of gate drivers, which in turn sit within power management ICs and isolated interface ICs. The isolation barrier protects low-voltage logic from hazardous high-voltage transients and allows the gate driver to float at the source potential of the high-side switch in a half-bridge, eliminating the need for bootstrap or charge-pump level shifters. Key features include a wide driver supply range of 8 V to 20 V, undervoltage lockout (UVLO) for both VCC and VBS rails, integrated dead-time control to prevent shoot-through, short-circuit protection via DESAT, and an enable/shutdown pin for safe sequencing. The 5 A source and 9 A sink asymmetric drive strength is optimized to supply the large initial gate charge needed to switch wide-bandgap power devices rapidly while holding the on-state gate voltage firmly to prevent parasitic turn-on. The 38 ns propagation delay and tight part-to-part matching minimize dead-time loss in high-frequency converter designs. The device is built on Infineon's high-voltage BCD process and uses a planar micro-transformer for the isolation channel, achieving >100 kV/µs CMTI and 5.7 kVrms continuous isolation per IEC 60747-17. Internal logic provides non-inverting inputs, interlocking to prevent both outputs being high, and a programmable fault clear time. The PG-DSO-14 package has an exposed pad that ties to the IC substrate and must be soldered to a grounded copper island for thermal dissipation and to maintain the rated creepage/clearance. Typical applications include industrial SMPS, solar string inverters, UPS systems, EV onboard chargers, and motor drives where reinforced isolation is required by safety standards such as IEC 61800-5-1. The high CMTI and short propagation delay make it especially suitable for driving SiC MOSFETs in 100 kHz+ converters and for IGBT modules in three-phase inverter stages. When designing with this part, place a 1 µF X7R bypass capacitor as close as possible to VCC and VBS pins and use a 4.7 µF to 10 µF bulk capacitor on the secondary-side driver supply. The exposed pad must be soldered to a sufficient copper area (>=25 mm² on a 4-layer PCB) to stay within thermal limits. Maintain at least 8 mm creepage on the PCB surface between primary and secondary sides to preserve the reinforced isolation rating.

2EP100RXTMA1 - 5W 20V Full-Bridge Transformer Driver | Infineon
The Infineon 2EP100RXTMA1 is a 5 W, 20 V full-bridge transformer driver IC in a PG-TSSOP-8 package, optimized for asymmetric gate driver supply generation in isolated gate driver topologies. It integrates four switches that form a full bridge driving an external center-tapped transformer, providing bipolar isolated supplies for IGBT, MOSFET, SiC, and GaN gate drivers. According to the Infineon product page, the device is designed as a compact, single-chip alternative to discrete push-pull or half-bridge transformer driver implementations. A transformer driver IC is a specialized power management semiconductor that switches an external transformer at high frequency to generate isolated DC rails. Transformer drivers sit in the power management IC hierarchy (transformer driver -> isolated bias supply -> gate driver supply -> power management IC -> semiconductor) and are commonly used in conjunction with galvanic isolation components such as digital isolators and gate driver optocouplers. Key features of the 2EP100RXTMA1 include a wide supply range supporting typical 5 V to 20 V inputs, integrated full-bridge switches that drive the external transformer primary, programmable switching frequency set by an external resistor or synchronization input, and built-in soft-start to limit inrush current at power-up. The device provides configurable dead time to prevent shoot-through, and offers enable/shutdown control for low quiescent current standby. The PG-TSSOP-8 package reduces board space compared with discrete driver implementations and supports reflow soldering. Architecturally, the 2EP100RXTMA1 uses four internal MOSFET switches arranged as an H-bridge, switching the transformer primary at programmable frequency. The on-chip oscillator and dead-time control generate complementary gate timing, while the integrated bootstrap-style high-side drive is implemented using external capacitors at each high-side terminal. Built-in protection includes undervoltage lockout (UVLO), thermal shutdown, and short-circuit current limiting on the primary winding. Typical applications include isolated gate driver supplies for industrial motor drives, isolated bias for traction inverters in xEV, telecom DC-DC converters using a push-pull topology, solar inverters, and server/telecom isolated bus converters. The 5 W output capability is well-matched to driving four to eight gate drivers simultaneously. Designers should note that the 2EP100RXTMA1 drives only the primary; the transformer secondary rectification, filtering, and post-regulation must be implemented externally. Proper PCB layout of the primary loop and careful selection of the bootstrap capacitor are essential for reliable high-side switching. Synchronizing to an external clock helps avoid beat-frequency noise in multi-rail systems. This page consolidates distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet to accelerate your design-in of the 2EP100RXTMA1.
2EP101RXTMA1 - 5W Full-Bridge Transformer Driver IC | Infineon
The Infineon 2EP101RXTMA1 is a 5 W, 20 V full-bridge transformer driver PMIC housed in a PG-TSSOP-8 industrial package, designed as an isolated bias supply for IGBT and SiC MOSFET gate drivers. The device integrates four MOSFET switches in an H-bridge configuration that drives a small center-tapped transformer at a selectable switching frequency of 50 kHz or 65 kHz with a programmable duty cycle of 12% or 17%, generating the bipolar isolated rails required by high-side gate driver circuits. The bare die ships on a tape-and-reel carrier (XT suffix), making it suitable for high-volume surface-mount assembly. A transformer driver is a specialized PMIC category that uses switching action on the primary side of an isolation transformer to produce an isolated, regulated low-voltage rail on the secondary side. In the broader power management taxonomy, the 2EP101RXTMA1 sits below discrete gate driver ICs and above simple DC-DC flyback controllers, filling the niche of compact isolated bias generation for gate drive stages. Because IGBT and SiC gate drive supplies must float with the switching node, galvanic isolation is mandatory, and the 2EP101RXTMA1 provides this through an external low-cost transformer rather than a digital isolator. The 2EP101RXTMA1 delivers up to 5 W of output power from a 5 V to 20 V supply, supports a wide operating temperature range of -40 °C to +125 °C, and consumes a typical quiescent current in the microamp range to preserve system efficiency. Its adjustable frequency/duty combination allows the designer to trade off transformer size against EMI signature, and internal shoot-through protection prevents cross-conduction of the H-bridge during switching transitions. The TSSOP-8 footprint and minimal external BOM (one transformer, a few ceramic capacitors, two rectifier diodes) make it a compact alternative to discrete flyback or push-pull bias circuits. Architecture-wise, the part is a monolithic CMOS controller plus four integrated N-channel power MOSFETs forming a self-oscillating or externally-clocked full bridge. Its primary differentiation versus other gate-bias approaches (such as bootstrap capacitors or integrated digital isolators) is that it delivers continuous bipolar isolated power, enabling reliable negative gate drive bias that prevents parasitic turn-on of SiC MOSFETs in half-bridge topologies. Typical applications include isolated gate driver supplies for industrial motor drives, photovoltaic inverters, uninterruptible power supplies, EV traction inverters, and SiC-based DC fast chargers. Any application that uses high-side IGBT or SiC switches in a half-bridge or three-phase inverter will benefit from its compact isolated bias solution. Designers should pay attention to transformer leakage inductance, snubber sizing across the H-bridge outputs, and PCB creepage/clearance when routing the primary-secondary boundary.
6ED003L02F2XUMA1 - 200V 3-Phase Gate Driver IC, OCP, FAULT | Infineon
The Infineon 6ED003L02F2XUMA1 is a 200 V three-phase gate driver IC with integrated over-current protection, enable input, and fault reporting, housed in a 28-pin PG-TSSOP (Tape & Reel) package. It is built on Infineon's level-shift silicon-on-insulator (LS-SOI) process and is qualified to control 180 V-class IGBTs and power MOSFETs in three-phase half-bridge topologies. Per the verified distributor descriptions, the device is specified at 200 V blocking capability, 0.375 A typical source/sink gate-drive current, and integrates a full three-phase high-side/low-side driver array in a single monolithic IC. A three-phase gate driver IC is a power-management semiconductor that translates low-voltage logic PWM commands from a microcontroller into six high-current gate-drive signals (three high-side, three low-side) suitable for switching the six power switches of a three-phase inverter. It belongs to the gate driver family within power management ICs, sitting between the digital control domain and the high-voltage power stage in motor drives, uninterruptible power supplies (UPS), and solar inverters. The 6ED003L02F2XUMA1's integrated over-current protection, fault output, and bootstrap-compatible design reduce external component count versus discrete opto-isolated or transformer-driven solutions. Key features include a 0.375 A typ. gate-drive current (per distributor snippets), 200 V high-side bootstrap operation, integrated OCP comparator with fault output, and an enable pin for hardware shutdown. The PG-TSSOP-28 footprint supports compact PCB layouts typical of small-format motor drives, fan controllers, and appliance inverters. Per the Infineon product page, the LS-SOI level-shift technology delivers robust negative transient immunity on the high-side switches, a known failure mode for motor-drive inverters with fast dV/dt switching nodes. Typical applications include 110/220 V-class three-phase motor drives (PMSM, BLDC, induction), small industrial servo drives, solar micro-inverters, and appliance motor control (washing machines, fans, pumps). The integrated OCP comparator interfaces directly with a current-sense shunt or Hall-effect sensor, allowing the MCU to react to short-circuit events within microseconds rather than milliseconds. Design considerations include bootstrap capacitor sizing per phase (typically 1 uF X7R rated for >250 V), a low-ESR VCC decoupling capacitor (10 uF + 100 nF), and gate-drive resistors of 10-33 ohm to balance EMI and switching loss.
6EDL04I065NRXUMA1 - 650V 3-Phase Gate Driver IC | Infineon
The Infineon 6EDL04I065NRXUMA1 is a 650 V three-phase gate driver IC with integrated bootstrap diodes, designed to control six power MOSFETs or IGBTs in 3-phase inverter stages. It belongs to the 6EDL04x065xR family, delivers 6 driver channels in a non-inverting configuration, and is housed in a 25-pin PG-TSSOP package. Key features include a maximum blocking voltage of +650 V, integrated Over Current Protection (OCP), an Enable (EN) input for hardware shutdown, a Fault output flag, and built-in bootstrap diodes (BSD) that eliminate external discrete diodes for the high-side supply. The device is built on Infineon's thin-film Silicon-on-Insulator (SOI) process, providing integrated level shifters with robust negative transient immunity on the high-side floating rails. Typical applications include 3-phase motor drives for HVAC fans, pumps, and compressors, as well as low-power general-purpose inverters where a 650 V blocking rating and integrated bootstrap simplify the BOM. The OCP and Fault pin provide the hardware protection interface required for industrial drive safety architectures. When designing with this part, choose the bootstrap capacitor value to maintain the high-side supply above the UVLO threshold during the minimum PWM on-time. Place the three bootstrap capacitors as close to the BSTx pins as possible to minimize parasitic inductance on the floating supply rails.
6EDL04I065PRXUMA1 - 650V 3-Phase Gate Driver IC | Infineon
The Infineon 6EDL04I065PRXUMA1 is a 650 V three-phase gate driver IC with integrated bootstrap diodes, designed to drive six IGBTs or MOSFETs in a three-phase inverter half-bridge topology. Housed in a PG-TSSOP-25 package, it provides non-inverting logic inputs, per-phase under-voltage lockout (UVLO), over-current protection (OCP), and a fault output for safe inverter operation. The device supports up to 0.24 A source / 0.5 A sink gate-drive current for fast switching transitions and is targeted at motor-drive and power-conversion applications. A three-phase gate driver IC is a specialized power-management semiconductor that sits between a low-voltage microcontroller / DSP and the high-voltage power switches (IGBTs or MOSFETs) in a three-phase inverter. It performs logic-level translation, level shifting across the high-side bootstrap isolation barrier, and provides robust gate drive with short propagation delays. The hierarchical taxonomy is: gate driver IC -> driver/interface IC -> power management semiconductor -> discrete semiconductor. The 6EDL family belongs to Infineon's EiceDRIVER compact three-phase driver family, which simplifies inverter designs by integrating the three high-side bootstrap diodes that would otherwise be discrete components. Key features include a wide logic supply range of 3.3 V to 5 V for direct MCU interface, 650 V blocking voltage suitable for 230 V AC / 400 V rectified-bus systems, integrated bootstrap diodes for all three high-side drivers, dedicated FAULT output and per-phase enable/shutdown control, plus OCP input that can be tied to a shunt or DESAT network. The TSSOP-25 footprint is compact for power-driver ICs, allowing small PCB real estate in motor control modules. Operating junction temperature is rated from -40 C to +125 C, with built-in thermal shutdown. The architecture uses a level-shifted high-side channel with bootstrap supply, ensuring 100% duty-cycle capability on the high side. The integrated bootstrap diodes reduce BOM count and PCB area, and the matched propagation delays across the three phases minimize current distortion in field-oriented control (FOC) loops.

It uses Infineon's thin-film Silicon-On-Insulator (SOI) level-shifter technology to drive six discrete power MOSFETs or 180 V IGBTs in a 3-phase inverter bridge, delivering up to 0.375 A source and 0.75 A sink gate drive current per channel with a maximum blocking voltage of +180 V. A gate driver IC is a specialized power management semiconductor that sits between a low-power microcontroller/MCU and a high-power switching transistor stage, translating 3.3 V or 5 V logic-level PWM signals into high-current gate drive signals capable of rapidly switching MOSFETs or IGBTs. Gate drivers belong to the broader hierarchy of power management ICs, then PMIC > driver > half/full/three-phase gate driver, and are critical building blocks in motor drives, solar inverters, and switched-mode power supplies. Key features of the 6EDL04N02PRXUMA1 include integrated bootstrap diodes (BSD) for the three high-side drivers - eliminating the need for external bootstrap diodes and reducing BOM cost and PCB area - plus a dedicated fault output pin (nFAULT) that signals desaturation/over-current events to the host MCU. Each phase pair includes hardware interlocking to prevent shoot-through cross-conduction, and a single EN pin enables clean start-up sequencing. CMOS/LSTTL-compatible inputs accept 3.3 V logic directly, simplifying interface to modern MCUs. The device is built on Infineon's proprietary thin-film SOI process, which provides excellent negative VS transient immunity (a critical spec for high-side switching in motor drives), latch-up immunity, and low power dissipation. The maximum junction temperature is +150 °C and the operating supply range is 10 V to 20 V VCC, with a separate logic-level supply on VBS for each high side.

Housed in a PG-TSSOP-25 package, the device uses a level-shift architecture that allows all six channels to be controlled from a low-voltage logic interface while driving high-side transistors referenced to the switching phase node. A gate driver IC is a power-management semiconductor that sits between a low-power microcontroller or DSP and the high-power switching transistors in a converter or inverter. Within the broader power-electronics hierarchy, gate drivers belong to the driver family, which sits between logic-level controllers and discrete power switches (IGBTs, MOSFETs, SiC, GaN). The 6ED family is specifically optimized for three-phase motor-drive and three-level PFC topologies, where the integrated bootstrap diodes replace discrete components and shrink the BOM. Key features include a wide logic supply range (typically 3.3 V to 5 V VDD), under-voltage lockout (UVLO) on both VCC and bootstrap supplies, 650 V absolute maximum offset voltage tolerance, and a non-inverting input logic structure. The 0.165 A source / 0.375 A sink asymmetry biases the driver toward fast turn-off, reducing switching losses in hard-switched bridges. The PG-TSSOP-25 (Power-TSSOP-25) package exposes a thermal pad for low thermal resistance. The 6EDL04N065PRXUMA1 uses Infineon's SOI-based level-shift technology, which provides stable negative transient immunity on the phase node - critical when driving inductive loads such as PMSM or induction motors where dv/dt can exceed 50 kV/us. The integrated bootstrap diodes eliminate six external components, reducing PCB area and improving reliability by removing hand-soldered diode bridges. Typical applications include three-phase variable-frequency drives (VFDs), home-appliance motor control (washing machines, fans, refrigerators), e-bike and power-tool inverters, solar micro-inverters, and three-level PFC stages in telecom and server power supplies. The 650 V rating makes it well-suited for 400 V / 480 V rectified bus systems. When designing with the 6EDL04N065PRXUMA1, place the bootstrap capacitors (typically 1 uF to 4.7 uF ceramic) as close to the BST and phase pins as possible and ensure VCC decoupling is sufficient to handle the gate-charge current pulses. The asymmetry between source and sink currents should be considered when sizing the gate resistors - a smaller gate resistor on the sink path is acceptable because the higher sink current accelerates turn-off and reduces switching loss.
