L6384ED013TR is a high‑voltage half‑bridge gate driver IC from STMicroelectronics (ST).

The L6384ED013TR is a high‑voltage half‑bridge gate driver IC from STMicroelectronics (ST), belonging to the L6384E series. The suffix TR stands for Tape&Reel shipping format. It is supplied in SOIC‑8 (SOP‑8) SMD package. It drives N‑channel MOSFETs or IGBTs to construct half‑bridge power circuits. With an integrated bootstrap diode, it supports a maximum bus voltage of 600 V. It is widely used in power conversion, motor drive, induction heating and other power circuits, and the device is currently in mass production.

Part number breakdown: L6384ED = device core; 013 = SO‑8 SMD version; TR = Tape&Reel packaging.

3. Application Scope (Advantages and Limitations)

Preferred Application Scenarios

Motor Drive (one phase of half‑bridge / three‑phase bridge)For DC motors, PMDC (Permanent‑Magnet DC) motors and PMAC (Permanent‑Magnet AC) motors. Three pieces of L6384ED013TR can build a complete three‑phase inverter for BLDC (Brushless DC) motors. Typical uses include fans, water pumps, small industrial actuators and household appliance motor drives.

Switching Power Supplies, DC‑AC Inverters, Half‑Bridge Resonant Power SuppliesHalf‑bridge power supplies, LLC resonant converters and low‑power inverters with bus voltage up to 600 V, applicable to household power supplies and industrial auxiliary power supplies.

Induction Heating EquipmentDriving small induction heating coils for high‑frequency half‑bridge power conversion. This is an officially recommended application by ST.

HVAC EquipmentAuxiliary driver boards for air‑conditioner fans and compressors, household variable‑frequency boards.

Lighting Power SuppliesHigh‑power LED driver power supplies and electronic ballasts adopting half‑bridge topology.

Factory Automation and Small‑Sized Industrial EquipmentSmall industrial drivers, solenoid valve power conversion, power‑drive sections on industrial control boards.

Limitations & Selection Notes

It is not an automotive‑grade device without AEC‑Q100 qualification and shall not be directly used in automotive products. ST automotive‑grade gate driver series shall be selected for automotive applications.

Peak drive current is 400 mA (source) / 650 mA (sink), suitable for medium‑and‑small‑power MOSFETs and IGBTs. For power devices with extremely large gate charge, the driving capability is insufficient. An external push‑pull buffer is required or a higher‑current driver IC shall be adopted instead.

One single chip implements only one half‑bridge (one high‑side + one low‑side channel). Three chips are required for three‑phase BLDC implementation.

The input features inverting logic. Logic inversion shall be considered for PWM firmware programming, which is a common pitfall for customers.

The maximum bus voltage is 600 V and must not be exceeded. High‑voltage creepage distance rules must be strictly followed for high‑voltage power PCB layout.
