FAN7383MX Présentation
A half-bridge gate driver is a type of FET/IGBT driver (a sub-category of power management ICs) that supplies the high peak gate charge currents required to switch the high-side switch of a synchronous half-bridge or full-bridge power stage. Compared to gate-drive transformers or bootstrap-only discrete designs, an integrated half-bridge driver IC such as the FAN7383MX adds level shifting, a stable bootstrap diode for the high-side rail, dead-time insertion to prevent shoot-through, and logic-level PWM input compatibility - replacing dozens of discrete components with one IC.
Key features include 600V high-side offset voltage (allowing operation on 400V-class rectified bus rails), built-in common-mode noise cancellation for stable high-dv/dt operation, an SD (shutdown) input, and a programmable dead-time range that optimizes turn-on/turn-off timing for MOSFET or IGBT switches. The 14-SOP footprint gives it a small board area while still allowing conventional hand-soldering and visual inspection, which is uncommon for high-voltage gate drivers that are typically SOIC-8 or smaller.
Architecturally, the FAN7383MX uses onsemi's high-voltage BCD process with an advanced level-shift circuit that translates the PWM input reference (ground) to the floating high-side rail, plus a noise-canceling technique that rejects the large dV/dt transients seen on the switching node (HS pin). The DT pin sources a current set by R_DT through an internal resistor network, which controls the dead time between HO and LO transitions.
Typical applications include 3-phase inverter motor drives (HVAC compressors, small industrial fans, washing-machine variable-frequency drives), half-bridge and full-bridge switch-mode power supplies (telecom rectifiers, server PSUs), electronic ballasts for fluorescent and HID lighting, induction-heating cooktops, and solar micro-inverter half-bridge stages.
When designing with this part, choose the dead-time resistor R_DT to be slightly longer than the switch turn-off delay to prevent cross-conduction; too long a dead-time wastes body-diode conduction time and increases losses. The bootstrap capacitor CBST must be sized to supply the high-side gate charge plus quiescent current across the longest PWM off-time, and the VBS supply should be locally decoupled with a ceramic bypass capacitor.

Applications typiques
FAN7383MX convient pour 6 applications: 3-Phase Variable-Frequency Motor Drive (HVAC Compressor / Fan), Half-Bridge / Full-Bridge Switch-Mode Power Supply, Electronic Ballast for Fluorescent / HID Lighting, Induction-Heating Cooktop Half-Bridge Stage, Solar Micro-Inverter Half-Bridge Stage, Battery-Powered Wireless / Portable Tool BLDC Drive.
3-Phase Variable-Frequency Motor Drive (HVAC Compressor / Fan)
The FAN7383MX drives one half-bridge leg of a 3-phase VFD inverter for HVAC compressors, industrial fans, and washing-machine variable-frequency motors up to roughly 1-3 kW. Its 600V high-side offset tolerates a 400V rectified DC bus, the 0.65A sink current switches most 600V-class IGBTs cleanly, and the programmable DT pin lets the designer tune dead-time to the specific IGBT turn-off delay. Use three FAN7383MX ICs to drive all three half-bridge legs; pair with bootstrap caps sized for the longest PWM off-time plus VBS quiescent current.
Recommandé
Half-Bridge / Full-Bridge Switch-Mode Power Supply
In telecom and server half-bridge or full-bridge SMPS stages the FAN7383MX drives the primary-side MOSFETs from a 400V bus. The built-in dead-time control (R_DT at DT pin) prevents shoot-through between the high-side and low-side MOSFETs, and the 14-SOP package allows conventional hand-soldering and visual inspection during prototyping. Use a bootstrap diode to VBS and a local ceramic bypass on VCC for clean switching under high dV/dt on the switching node.
Recommandé
Electronic Ballast for Fluorescent / HID Lighting
Electronic ballasts for fluorescent tubes and HID lamps use a half-bridge resonant inverter operating from a rectified mains bus. The FAN7383MX fits this topology directly: the 600V high-side rating handles the rectified 220V or 277V mains, and the 0.65A sink / 0.35A source current is sufficient for the low-current IGBTs or MOSFETs used in lamp-ballast half-bridges. The SD (shutdown) pin supports lamp-out protection by disabling both gate outputs on fault conditions.
Recommandé
Induction-Heating Cooktop Half-Bridge Stage
Induction-heating cooktops use a resonant half-bridge to drive the heating coil at 20-100 kHz. The FAN7383MX drives the 600V-class IGBTs in this resonant tank with programmable dead-time that prevents cross-conduction during resonant zero-voltage switching transitions. The internal common-mode dV/dt noise cancellation keeps the high-side channel stable when the switching node swings at hundreds of volts per nanosecond.
Recommandé
Solar Micro-Inverter Half-Bridge Stage
Grid-tie solar micro-inverters convert the PV panel DC output to AC through a DC-DC stage followed by a DC-AC inverter. The FAN7383MX drives the primary-side MOSFETs of the DC-DC half-bridge on a 400V-class rectified PV bus, or the line-frequency unfolding switches in the DC-AC stage. The SD pin enables fast shutdown for anti-islanding protection required by UL 1741 and IEEE 1547 grid-tie safety standards.
Recommandé
Battery-Powered Wireless / Portable Tool BLDC Drive
Cordless power tools and battery-operated appliances use low-voltage BLDC motors; however, higher-power 18V/36V-class tools still benefit from a half-bridge gate driver to reduce MCU pin-drive losses. The FAN7383MX can be used in such applications on the low-voltage side (e.g., 48V bus) where its high-side rating provides large margin and the SD pin supports fault shutoff. The 14-SOP footprint suits compact tool-motor PCBs.

Notes de conception
Size the bootstrap capacitor CBST to supply the high-side gate charge QG plus the VBS quiescent current IQBS over the longest PWM off-time. Rule of thumb: CBST >= (QG + IQBS * t_OFF_max) / dV_BS, with dV_BS typically allowed to drop 0.5V-1V from the regulated 15V VCC. A 0.1uF-1uF X7R ceramic is a typical starting point for 600V-class IGBTs; verify by measuring VBS ripple on the scope under worst-case duty cycle.
Setting dead-time too short causes shoot-through (both high-side and low-side switches momentarily ON) and catastrophic bus short. Setting dead-time too long increases body-diode conduction time and switching losses. The R_DT value should be chosen to provide dead-time slightly longer than the worst-case switch turn-off delay (t_off(max)) at the lowest operating temperature. The onsemi FAN7383 datasheet contains a graph of R_DT versus dead-time in nanoseconds; consult it during design.
Place the VCC bypass capacitor (typically 0.1uF X7R) within 5 mm of the VCC pin and the VBS bypass (1uF X7R) directly across VB to VS. Keep the gate-drive traces (HO, LO) short and away from the switching node (HS/VS) to minimize capacitive coupling and ringing. Use a ground plane under the low-side driver and gate-loop return paths, and consider a 4-layer PCB with a dedicated return layer if the design must pass stringent EMI tests such as CISPR 11/22.
Estimated: at continuous 100 kHz switching into a 50 nC gate charge, gate-drive losses are roughly P_gate = QG * VCC * f_sw = 50e-9 * 15 * 100e3 = 0.075 W per output, totaling ~0.15 W for both HO and LO. The 14-SOP package has theta_JA around 100-120 C/W on a 1 oz 2-layer board, giving a junction temperature rise of 15-20 C - well within the 125 C operating limit. Verify with measured case temperature in production.
