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. Per-channel UVLO prevents the power switches from operating in their linear region, which is critical for efficiency and reliability. Typical applications include three-phase motor drives for HVAC compressors, refrigerator compressors, washing-machine pumps, industrial fans and pumps, e-bike and small-EV traction inverters, and uninterruptible power supplies (UPS) up to the 400 V class. The compact form factor also makes it suitable for appliance inverter boards where PCB area is constrained. When designing with the 6EDL04I065PRXUMA1, the bootstrap capacitor value must be sized to supply gate charge during the high-side on-time without dropping below UVLO; a 1 uF to 4.7 uF ceramic is a common starting point. PCB layout should keep the low-side return loop compact, and the OCP filter RC should be placed close to the OCP pin to avoid false tripping in noisy switching environments. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet - giving an engineer a faster path from datasheet to working inverter prototype.
6EDL04N02PRXUMA1 - 200V 3-Phase Gate Driver IC | Infineon
The Infineon 6EDL04N02PRXUMA1 is a 200 V three-phase gate driver IC with integrated bootstrap diodes, over-current protection, enable input, and fault reporting, housed in a 28-pin TSSOP (PG-TSSOP-28) package. 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. Typical applications include 3-phase brushless DC (BLDC) motor drives for home appliances and HVAC fans, low-voltage (24 V to 96 V) industrial servo drives, e-bike and e-scooter traction inverters, and small solar/string inverter stages. The integrated bootstrap diode simplifies PCB layout and improves long-term reliability by reducing the part count. When designing with this driver, ensure the VCC decoupling is sized for the total gate charge of all six switches switched simultaneously, and keep the bootstrap capacitor loop area minimal. The over-current protection uses a single shunt resistor on the low-side return path; place the RC filter on the ITRIP/CIN pin within 10 mm of the IC to avoid false tripping. This page synthesizes distributor pricing across six sources, verified drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
6EDL04N03PRXUMA1 - 3-Phase Gate Driver, 25V/0.24A | Infineon
The Infineon 6EDL04N03PRXUMA1 is a 200 V/600 V three-phase gate driver IC with integrated bootstrap diodes, over-current protection (OCP), fault output, and enable (EN) function, supplied in a 25-pin PG-TSSOP package. It delivers 0.24 A source/0.375 A sink gate-drive current per channel and operates from a supply range of 10 V to 25 V (VDD) with logic input levels referenced to 3.3 V/5 V VSS. A three-phase gate driver is a specialized power-management IC that controls the six switching transistors (three high-side + three low-side) of a 3-phase inverter used in motor drives and DC/AC converters. Within the broader semiconductor hierarchy, this device is a sub-category of gate drivers, which in turn belong to the power management IC family. By integrating six half-bridge channels, three bootstrap diodes, and protection logic in a single package, the 6EDL04N03PRXUMA1 replaces a discrete driver + bootstrap-diode + comparator solution, reducing PCB area and BOM count. Key differentiating features include a 60 ns typical rise time and 26 ns typical fall time at 1 nF load, integrated charge-pump-less bootstrap with low-ohmic current-limiting resistors for fast recharge at small duty cycles, over-current shutdown with adjustable threshold, an EN pin for hardware interlocking, and an open-drain FAULT output for diagnostic feedback to the MCU. The device also provides built-in dead-time generation and shoot-through protection, eliminating the risk of cross-conduction in the driven half-bridge. The 6EDL04N03PRXUMA1 is built on Infineon's high-voltage SOI (silicon-on-insulator) gate-driver process, which provides excellent negative transient immunity on the VS node (-VS transient robustness) and allows operation in harsh motor-drive environments. Logic inputs are 3.3 V/5 V VSS-compliant, eliminating the need for external level shifters when interfaced with low-voltage MCUs. Typical applications include BLDC and PMSM motor drives for home appliances, ceiling fans, pumps, and HVAC blowers, as well as 3-phase solar inverters, industrial servo drives, and e-bike/e-scooter traction controllers. The integrated OCP and EN/FAULT pins also suit safety-critical designs requiring functional shutdown on detection of short-circuit or over-temperature events. When designing with this part, pay close attention to the bootstrap capacitor selection and to PCB layout of the VS floating supply traces to prevent ground bounce. A low-ESR ceramic or tantalum capacitor (1 uF to 4.7 uF) on each CBOOT node is recommended, with the high-side gate-drive loop kept as short as possible.

6EDL04N065PRXUMA1 - 650V 3-Phase Gate Driver IC | Infineon
The Infineon 6EDL04N065PRXUMA1 is a 650 V three-phase gate driver IC with integrated bootstrap diodes, delivering 0.165 A source current and 0.375 A sink current per channel for driving IGBTs and power MOSFETs in motor control and power conversion applications. 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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet - enabling engineers to evaluate the part alongside parametric peers on a single page.

Isolated gate drivers are essential components in power electronics systems where the control circuitry must be electrically isolated from the high-voltage power stage. They transmit switching signals across an isolation barrier while providing sufficient drive current to charge and discharge the gate capacitance of power switches. The ADUM3220ARZ integrates the isolation and driver functions in a single IC, eliminating the need for external pulse transformers and simplifying PCB design.

It operates over a wide supply voltage range and supports high junction temperatures up to 125°C. The device is RoHS compliant and lead-free, meeting modern environmental standards. The ADUM3220ARZ uses iCoupler technology, which employs chip-scale transformers to achieve isolation. This approach offers superior performance compared to optocouplers, including higher data rates, lower power consumption, and better timing accuracy. The driver's output stages are designed to deliver high peak current for fast switching, reducing switching losses in power converters. Typical applications include isolated switch-mode power supplies, motor drives, solar inverters, and industrial automation systems. The ADUM3220ARZ is particularly well-suited for driving IGBTs and MOSFETs in half-bridge or full-bridge configurations, where its dual-channel architecture and precise timing ensure reliable operation. When designing with the ADUM3220ARZ, it is important to provide adequate decoupling on the input and output supplies and to minimize parasitic inductance in the gate drive loop. Proper PCB layout is critical to achieve the specified timing and isolation performance.
