FD6288 Overview
The Fortior Tech FD6288 is a 3-phase half-bridge gate driver IC that integrates three independent high-side and low-side driver channels into a single package, targeting compact and cost-effective motor drive inverter designs. Built to support N-channel MOSFET and IGBT power stages in 3-phase bridge topologies, the FD6288 accepts a power supply from 4.8V to 20V and supports a floating high-side absolute voltage of up to +250V, making it compatible with motor drive systems powered from rectified mains or high-voltage DC bus rails. The device is fully compatible with both 3.3V and 5V logic input levels, enabling direct interfacing to modern ARM Cortex-M, ESP32, and PIC32 microcontrollers without additional level-shifting circuitry.
Fortior Tech has incorporated several key system-level protection and convenience features directly into the FD6288. Built-in 200ns dead time prevents simultaneous conduction of high-side and low-side switches in each half-bridge leg — eliminating the shoot-through risk that can destroy power MOSFETs or IGBTs without requiring dead-time insertion in firmware. Complementary shoot-through prevention logic and built-in input filtering further enhance robustness against noise-induced false triggering, which is particularly valuable in the electrically noisy environment of a switching power stage. VCC and VBS undervoltage lockout (UVLO) on both the logic supply and the bootstrap supply rails prevents erroneous gate switching under supply ramp-up or brown-out conditions, protecting the power stage during start-up and fault recovery.
Output drive capability is specified at +1.5A source (IOH) and -1.8A sink (IOL), with matched high-side and low-side channels and symmetrical rise and fall times of 12ns each — ensuring consistent switching waveforms across all three phases and simplifying EMI management. The FD6288 output is in-phase with its input, conforming to standard 3-phase PWM drive conventions. Available in both TSSOP-20 and QFN-24 packages, the FD6288 suits a wide range of PCB layout preferences. ABL Semi stocks the FD6288 as a fully authentic, original Fortior Tech factory product, with flexible MOQ and compliance documentation for UK and European customers.

Applications
The FD6288 is designed for 3-phase N-channel MOSFET and IGBT bridge drive applications across industrial, commercial, and consumer motor control systems. Primary application areas include BLDC motor drives, 3-phase inverters for e-bikes and e-scooters, servo drive systems, industrial fans and pumps, and solar microinverter power stages. The device is equally well-suited to cordless power tool motor controllers, UPS inverter stages, and home appliance variable-speed drive systems, where its built-in dead time, shoot-through protection, and dual-logic-level compatibility simplify both hardware design and firmware integration.
Pin-to-Pin Compatible Alternatives
The FD6288’s TSSOP-20 and QFN-24 packages and standard 3-phase half-bridge driver pinout are compatible with several widely deployed Western gate driver ICs, enabling direct footprint substitution to reduce BOM cost and improve supply chain flexibility without PCB redesign.
| Reference Part Number | Original Manufacturer | Why Choose FD6288 |
|---|---|---|
| IR2130 | Infineon (International Rectifier) | Classic 3-phase gate driver in SOIC/DIP; FD6288 provides a modern TSSOP/QFN replacement with built-in dead time, shoot-through prevention, and input filtering not present in the IR2130 |
| IR2136 | Infineon (International Rectifier) | 3-phase gate driver with fault output in SOIC-28; FD6288 offers equivalent 3-channel drive in a smaller TSSOP-20 footprint with integrated 200ns dead time at a lower unit cost |
| DRV8300 | Texas Instruments | 3-phase smart gate driver requiring external FETs; FD6288 provides a simpler integration path with built-in shoot-through prevention and dual 3.3V/5V logic compatibility at a more competitive price |
| HIP4086 | Renesas (Intersil) | 3-phase bridge driver in SOIC-28; FD6288 replaces it in a more compact TSSOP-20 or QFN-24 package with matched 12ns switching times and integrated UVLO on both VCC and bootstrap rails |
| L6393 | STMicroelectronics | Dual high/low-side gate driver requiring external combination for 3-phase; FD6288 integrates all three half-bridge channels in a single IC, reducing component count and simplifying PCB layout |
Frequently Asked Questions
Is FD6288 RoHS compliant?
Yes. The FD6288 is fully RoHS compliant. Fortior Tech manufactures the FD6288 in accordance with EU RoHS Directive 2011/65/EU, ensuring the device is free from restricted hazardous substances including lead and mercury. ABL Semi can provide full compliance and trade documentation upon request to support UK and European regulatory and procurement processes.
What are the pin-to-pin replacements for FD6288?
The FD6288 is a functionally compatible alternative to established 3-phase gate driver ICs including the Infineon IR2130 and IR2136, Texas Instruments DRV8300, Renesas HIP4086, and STMicroelectronics L6393, offering the same 3-phase half-bridge drive architecture with the added advantage of built-in dead time and shoot-through prevention. Refer to the compatibility table above for a detailed part-by-part comparison.
What is the minimum order quantity (MOQ) for FD6288?
ABL Semi offers flexible MOQ for FD6288, supporting both prototype quantities and mass production orders. Contact us for current stock and pricing.
What package options are available for FD6288?
The FD6288 is available in two package options: TSSOP-20 (thin shrink small outline, 20-pin) and QFN-24 (quad flat no-lead, 24-pin). The TSSOP-20 suits standard SMD PCB layouts where footprint compatibility with existing SOIC/TSSOP 3-phase gate driver designs is required, while the QFN-24 offers a more compact, thermally enhanced option for high-density motor drive PCBs. Contact ABL Semi to confirm current stock availability for each package variant.
Does the FD6288 require external bootstrap diodes for high-side gate drive?
Yes. Like most half-bridge gate drivers using a bootstrap high-side supply architecture, the FD6288 requires an external bootstrap capacitor connected between the VS (source of the high-side switch) and VB (bootstrap supply) pins on each channel, along with a bootstrap diode to charge the capacitor from VCC during the low-side conduction period. The bootstrap capacitor value is typically in the range of 100nF to 470nF depending on the switching frequency and gate charge of the external power devices. The built-in VBS undervoltage lockout monitors the bootstrap supply voltage on each channel and inhibits gate drive if it falls below the safe operating threshold, protecting the high-side MOSFET or IGBT from under-driven gate conditions.
