FD6288T Visão geral
A three-phase gate driver is a power management IC that sits between a microcontroller's PWM outputs and the six power MOSFETs (or IGBTs) of a three-phase inverter bridge. Within the semiconductor hierarchy, it belongs to the gate driver family of high-voltage integrated circuits (HVICs), which use level-shifting technology to translate low-voltage logic signals to the floating gate references required by high-side switches.
Key features include operation up to +250V on the high-side rail, a low-side logic supply range of 4.8V to 20V, and CMOS/LSTTL-compatible inputs that accept logic levels down to 3.3V, allowing direct connection to 3.3V MCUs. The output stage provides a high pulse-current buffer for fast gate switching, with matched 12ns typical propagation delays.
Protection and control functions include under-voltage lockout (UVLO) on both high- and low-side supplies, which prevents the external power devices from operating with insufficient gate voltage, built-in cross-conduction prevention, and deadtime insertion to protect the bridge from shoot-through. The HVIC process delivers a stable monolithic structure suitable for cost-sensitive high-volume motor drives.
Typical applications include brushless DC (BLDC) motor drives for drones and e-bikes, field-oriented control (FOC) servo drives, power tools, electric fans, and heat-pump compressor inverters. The high-voltage rating and integrated deadtime make it a compact single-chip solution for 48V to 220V DC bus inverters.
Design consideration: bootstrap high-side supplies require correctly sized bootstrap capacitors and diodes; at low PWM frequencies the bootstrap must hold charge between cycles, so verify ripple under worst-case duty cycle. Keep gate loops short to limit ringing.

Aplicações típicas
FD6288T é adequado para 6 aplicaçãos: Drone ESC and Multirotor Motor Drives, BLDC Motor Drives for Power Tools and E-bikes, Fan and Compressor Inverter Drives, FOC Servo and Robotics Drives, Three-Phase Inverters for Small Appliances, HV Gate Drive Prototyping and Educational FOC Platforms.
Drone ESC and Multirotor Motor Drives
The FD6288T fits high-voltage drone electronic speed controllers because its 250V rating far exceeds typical 6S-14S battery stacks, while the 1.5A/1.8A gate drive with 12ns typical delays switches MOSFETs fast enough to keep switching losses low at high PWM frequencies used in FOC ESCs. In an ESC, the FD6288T sits between the flight-controller MCU and six N-channel MOSFETs, level-shifting 3.3V PWM logic to the floating high-side gates via bootstrap supplies. Its built-in deadtime insertion and cross-conduction prevention protect the bridge during rapid commutation without external sequencing logic. The main trade-off versus integrated smart drivers is the absence of current sensing, so shunt-based or sensorless current estimation must be added externally.
Recomendado
BLDC Motor Drives for Power Tools and E-bikes
For e-bike controllers and cordless power tool inverters operating from 36V to 72V (and higher) DC buses, the FD6288T provides a single-chip, low-cost three-phase gate drive with margins up to 250V. Its 4.8V to 20V VCC range accepts common 12V or 15V gate-drive rails, and the UVLO prevents the external MOSFETs from running partially on during battery sag or startup, a common failure mode in battery-powered tools. The 3.3V-compatible CMOS/LSTTL inputs connect directly to motor-control MCUs. Because the driver is hardware-PWM only, overcurrent and stall protection must be implemented in the MCU firmware or with external comparators, which is the main design consideration versus integrated-protection drivers.
Recomendado
Fan and Compressor Inverter Drives
Ceiling fans, heat-pump compressors, and refrigerator inverter drives benefit from the FD6288T's high-voltage headroom on rectified 110V/220V AC mains buses, where the DC link can approach 310V - designs near this level should derate and verify against the 250V high-side rating. In these continuous-duty applications, the low 330uA typical quiescent current and modest gate-drive power keep driver losses negligible, while the integrated deadtime protects the bridge during slow compressor speed ramps. The TSSOP-20 package's surface-mount format suits cost-optimized single-board inverter designs. Bootstrap capacitor sizing must account for low PWM frequencies used at low compressor speeds, where the bootstrap must hold charge for longer intervals.
Recomendado
FOC Servo and Robotics Drives
Field-oriented-control servo drives for robotics use the FD6288T where its 12ns typical delay matching helps maintain symmetric PWM phase generation, important for low torque ripple. In a typical FOC board, the MCU outputs six center-aligned PWM channels; the FD6288T buffers and level-shifts them to the power stage. The SimpleFOC ecosystem demonstrates this configuration directly: a SimpleFOCMini-compatible board pairs one FD6288T with six 30V/5A NMOS transistors for compact FOC motor control. Since the driver lacks integrated current-sense amplifiers, designers add external shunt amplifiers or in-line sensors - a deliberate trade-off that keeps BOM cost low while preserving full current-loop flexibility in the MCU.

Three-Phase Inverters for Small Appliances
Small three-phase appliances - air-conditioner blowers, washing-machine direct-drive motors, and dishwasher pumps - use the FD6288T as the interface between a commodity MCU and a 600V-class or lower MOSFET/IGBT bridge operating well within the 250V limit on 120V AC-derived DC links. The driver's monolithic HVIC construction provides stable level shifting across the full temperature range of -40C to +125C, covering enclosed appliance thermal environments. Its low-side inputs accept 3.3V or 5V logic, and the 800mV output stage characteristic ensures solid gate swing on the external devices. Deadtime is inserted internally, simplifying firmware; designers should still confirm the fixed deadtime value suits their MOSFET switching times.

HV Gate Drive Prototyping and Educational FOC Platforms
Because the FD6288T is inexpensive (about $0.49 single-piece as of 2026-10-20), available through JLCPCB assembly, and well documented, it is widely used in open-source and educational three-phase driver boards. Prototypers value that one IC replaces three discrete half-bridge drivers, cutting layout area and BOM count, while the TSSOP-20 package is hand-solderable unlike fine-pitch QFN alternatives. Its 3.3V logic compatibility lets students connect any Cortex-M or RISC-V MCU directly. In learning platforms the absence of integrated protection is actually instructive - users implement UVLO monitoring, deadtime verification, and current sensing themselves. Bootstrap component selection on these boards teaches practical high-side supply design trade-offs.

Notas de projeto
Bootstrap supply design is the most common failure point with the FD6288T. Size the bootstrap capacitor for the worst-case duty cycle: at low PWM frequencies or near-100% high-side duty, the bootstrap must hold charge for the entire cycle. Use a low-ESR ceramic (typically 0.1uF to 1uF) close to the VB-HO pins and a fast-recovery or Schottky bootstrap diode rated above the bus voltage. Estimated: gate charge draw per cycle equals Qg of the power MOSFET plus level-shifter consumption, so total droop = n*(Qg + Iq*t_cycle)/Cboot; verify the resulting droop stays above the UVLO threshold.
Keep each gate drive loop (driver pin -> gate -> source -> driver return) as short and tight as possible. Place the FD6288T close to the power MOSFETs, route high-side and low-side gate returns separately back to the driver ground, and keep the VS (switch-node) trace short to limit dV/dt coupling into the high-side supply. Star or ground-plane referenced layout for the VCC/GND decoupling (0.1uF + 10uF) reduces supply bounce during simultaneous commutation of two phases.
The FD6288T provides deadtime insertion and cross-conduction prevention, but you must still confirm the fixed internal deadtime is longer than your MOSFET's switching times at your gate resistance; otherwise add external deadtime in the MCU PWM. Do not exceed the 250V high-side rating - derate rectified-mains designs (310V DC link) accordingly and consider the 300V-rated ZG6288 if more headroom is required. Finally, the driver has no fault feedback pin, so overcurrent and thermal protection must live in the MCU firmware with external shunt sensing.
