Product details

Overview

L6384ED from STMicroelectronics is a high-voltage half-bridge gate driver IC designed to control power MOSFETs or IGBTs in switching topologies. It features 600 V high-side rail capability, ±50 V/ns dV/dt immunity, 400 mA source / 650 mA sink output drive, 50/30 ns rise/fall times (1 nF load), and integrated bootstrap diode - enabling compact motor drive and induction heating inverters.

For engineers reviewing the L6384ED datasheet, L6384ED pinout, L6384ED application, or L6384ED equivalent, key selection criteria include deadtime programmability via external resistor, CMOS/TTL Schmitt-trigger inputs with hysteresis, undervoltage lockout (12 V turn-on / 10 V turn-off), internal VCC clamp (~15.6 V), and dual DIP-8/SO-8 package support.

Technical Context

The L6384ED implements a single-input, non-overlap half-bridge driver architecture with matched propagation delays between high-side (HVG) and low-side (LVG) outputs. Its floating high-side section operates up to 600 V referenced to VOUT, while logic-level inputs (V_IL ≤ 1.5 V, V_IH ≥ 3.6 V) interface directly with microcontrollers or PWM controllers.

Deadtime is set externally via resistor (R_DT) on the DT/SD pin, yielding tunable delay range of 0.4–3.1 µs; shutdown is activated when DT/SD voltage drops below 0.5 V. The integrated bootstrap driver replaces external fast-recovery diodes using a patented DMOS+diode structure with 125 Ω typical R_DS(on), reducing leakage and board area.

Key Specifications

Parameter	Value and Actual Design Meaning
High-side voltage rating	600 V max - supports direct connection to 400 VAC rectified bus without level-shifting circuitry
dV/dt immunity	±50 V/ns - prevents false triggering during fast-switching transients in noisy industrial environments
Output drive strength	400 mA source / 650 mA sink - ensures rapid MOSFET/IGBT turn-on/off with <100 ns propagation delay variation
Switching speed (CL = 1 nF)	50 ns rise / 30 ns fall - enables reliable operation at up to 400 kHz switching frequency
VCC clamping voltage	15.6 V typical - protects internal circuitry from overvoltage during startup or transient surges

Pinout & Package

Available in SO-8 surface-mount package (JEDEC MS-012AC, 5.0 × 6.2 mm body, 1.27 mm pitch) with standard thermal pad layout for industrial-grade PCB assembly.

Pin/Terminal	Circuit Role	Design Meaning
1 IN	Logic input	In-phase with HVG, inverted relative to LVG; CMOS/TTL compatible with hysteresis (V_IL ≤ 1.5 V, V_IH ≥ 3.6 V)
2 VCC	Low-side supply	Internally clamped at ~15.6 V; powers low-side driver and logic; UVLO active below 10 V
3 DT/SD	Deadtime/shutdown control	High-impedance pin: <0.5 V triggers shutdown; resistor-to-ground sets deadtime (0.4–3.1 µs)
4 GND	Power ground	Reference for low-side driver and logic; must be low-inductance connection to minimize noise coupling
5 LVG	Low-side gate output	Drives N-channel MOSFET/IGBT gate; 400 mA source / 650 mA sink; 0.3 V max. saturation voltage
6 VOUT	Floating reference	High-side output return node; must be routed with minimal loop area to suppress ground bounce
7 HVG	High-side gate output	Drives high-side switch gate; same current capability as LVG; referenced to VOUT not GND
8 VBOOT	Bootstrap supply	Charged via integrated DMOS driver; supplies high-side section; requires external C_BOOT capacitor

Key Features

Feature	Design Value
Integrated bootstrap diode	Replaces external fast-recovery diode; reduces leakage, board space, and BOM count

Programmable deadtime	Resistor-tuned (47–270 kΩ) deadtime eliminates need for external timing ICs or complex gate-delay networks
CMOS/TTL Schmitt inputs	Hysteresis improves noise immunity on control lines; pull-down ensures defined state during MCU reset
VCC voltage clamp	15.6 V Zener-like clamp prevents overvoltage damage during slow-ramp or surge conditions

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage half-bridge driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2104S	No integrated bootstrap diode; requires external HV fast-recovery diode; lower dV/dt immunity (±25 V/ns); 200 mA/340 mA drive	Suitable for cost-sensitive, lower-power (<500 W) applications where board space is less constrained	Select if legacy design uses IR21xx footprint and external diode is acceptable; avoid for high-noise or miniaturized designs
UCC27211D	Higher drive (4 A source/sink); no integrated bootstrap; separate high/low inputs; no deadtime programming; 120 V max. V_BS	Targeted at high-frequency GaN/SiC half-bridges up to 2 MHz; requires external bootstrap and deadtime IC	Choose only for >100 kHz SiC/GaN designs needing ultra-fast drive; not drop-in for 600 V IGBT/MOSFET applications

Compared with IR2104S and UCC27211D, the L6384ED uniquely combines 600 V capability, integrated bootstrap, programmable deadtime, and industrial-grade dV/dt immunity - making it optimal for mid-power (500 W–5 kW) induction, motor, and lighting inverters where reliability and component count matter.

FAQ

What is the maximum recommended switching frequency for the L6384ED?

The L6384ED is characterized for reliable operation up to 400 kHz with a 1 nF capacitive load, as confirmed by rise/fall time (50/30 ns) and propagation delay (200–300 ns) data. At higher frequencies, thermal limits and bootstrap capacitor recharge time become limiting factors - especially above 250 kHz in continuous conduction mode. Derating is advised for sustained >300 kHz operation in thermally constrained layouts.

Can the L6384ED drive both MOSFETs and IGBTs?

Yes - the L6384ED is explicitly qualified to drive both N-channel power MOSFETs and IGBTs in half-bridge configurations. Its 400 mA source / 650 mA sink capability meets gate charge requirements for devices up to ~50 nC, and its 600 V high-side rating supports common 600 V-class switches. The integrated bootstrap driver is optimized for MOSFET gate drive but functions reliably with IGBTs when V_GE thresholds and Miller plateau characteristics are within specification.

How is deadtime configured on the DT/SD pin?

Deadtime is set by connecting a resistor (R_DT) between pin 3 (DT/SD) and GND. Values from 47 kΩ to 270 kΩ yield deadtimes of 0.4–3.1 µs, respectively, based on a fixed 28 µA internal current source (I_REF). The pin must never float - stray capacitance or noise can cause unintended shutdown. Layout best practice mandates short, direct routing with minimal trace length and no nearby noisy signals.

Does the L6384ED require an external bootstrap diode?

No - the L6384ED integrates a patented bootstrap driver consisting of a high-voltage DMOS transistor and series diode, eliminating the need for an external fast-recovery diode. This reduces leakage current, PCB area, and potential failure points. However, if bootstrap recharge time is insufficient (e.g., very low duty cycle or high frequency), an external diode may be added in parallel to supplement charging - though this is rarely necessary in properly designed 50–200 kHz applications.
