Detailed Description

Single-channel, galvanically isolated gate driver IC for fast, safe, and efficient driving of high-side or low-side power transistors (IGBT, Si-MOSFET, SiC MOSFET). Part of Infineon’s EiceDRIVER family, designed for high-noise industrial and energy applications, offering reinforced isolation, strong immunity to dV/dt, fast propagation with low jitter, and built-in protection features for robust system design.

Key Features

Single isolated channel gate driver for IGBT/MOSFET/SiC MOSFET

Reinforced isolation for system safety and compliance

High common-mode transient immunity for noisy power stages

Fast propagation delay and low pulse-width distortion for precise switching

UVLO on primary/secondary sides to prevent unsafe operation at low supply

Output stage optimized for fast charge/discharge of gate

Input compatible with standard logic (typical 3.3 V/5 V)

Wide operating temperature range for industrial environments

Suited for high dV/dt nodes and fast-switching topologies (SiC readiness)

EiceDRIVER ecosystem support, app notes, and reference designs

Key Advantages

Higher efficiency and lower switching losses through strong gate control

Improved system reliability via reinforced isolation and protection

Better EMI robustness due to high CMTI and clean switching behavior

Simplified design-in with standard logic interface and clear pinout

Flexible use across topologies (half-bridge, full-bridge, PFC, LLC, etc.)

Scales from legacy silicon devices to modern wide-bandgap devices

Supported by Infineon’s mature safety certifications and lifecycle stability

Packaging

Type: SOIC-style wide-body isolated driver package (commonly used for reinforced isolation in this series)

Supplier code: Package / Case 16381 (verify exact mechanical drawing on the datasheet)

Material and compliance: Molded epoxy, RoHS compliant, typically halogen-free; MSL rating per datasheet

Size and creepage/clearance: Wide-body format to achieve long creepage/clearance distances required for reinforced isolation (refer to datasheet for certified dimensions and ratings)

Pin configuration (typical for this family):

- Primary/input side: VDD1, GND1, IN (and optional enable or control pins depending on variant)

- Secondary/output side: VDD2, GND2, OUT (and optional CLAMP, DESAT, fault/status pins depending on variant)

Thermal characteristics: θJA and θJC depend on PCB layout, copper area, airflow, and package; follow datasheet thermal metrics and layout guidelines for heat spreading

Electrical isolation properties: Reinforced isolation with certified test and working voltages (e.g., basic/reinforced per UL/IEC/VDE). For exact VISO, VIORM/VIOTM, surge, PD, and certification numbers, use the datasheet on our product page

Tape-and-reel and tray options available for automated assembly (confirm reel size, pitch, and quantity on the current page)
