Product details
Overview
FAN2310AMPX from onsemi is a high-speed, dual-channel, non-inverting MOSFET gate driver IC designed for driving high-side and low-side N-channel power MOSFETs in synchronous buck, half-bridge, and motor control topologies. It features 4-A peak sink/source current, 15-V VDD rating, and 10-ns propagation delay (typ) with matched channel timing.
For engineers reviewing the FAN2310AMPX datasheet, pinout, applications, or equivalent options, key selection criteria include drive strength under 5-V logic input, shoot-through prevention via built-in dead-time, thermal performance in DFN8 3×3 mm package, and compatibility with PWM controllers in DC-DC converters and BLDC drivers.
Technical Context
The FAN2310AMPX integrates two independent gate driver channels with TTL/CMOS-compatible inputs, internal level-shifting for high-side operation, and matched propagation delays to ensure precise timing alignment between upper and lower gate signals. Each channel delivers 4-A peak output current with <10-ns delay mismatch across temperature and supply voltage.
It employs undervoltage lockout (UVLO) on both VDD and VBS rails to prevent partial turn-on of power switches, and includes integrated bootstrap diode for high-side floating supply generation - eliminating external diode requirement in typical half-bridge configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 4.5 V to 15 V - supports direct connection to common 5-V or 12-V system rails without LDO regulation |
| Peak Output Current | ±4 A - enables fast switching of 10–50 nC gate charge MOSFETs at >1 MHz frequencies |
| Propagation Delay | 10 ns (typ) - ensures tight timing control critical for high-frequency synchronous rectification |
| Delay Matching | ≤1 ns (max) - minimizes dead-time uncertainty and reduces conduction loss in bridge legs |
| UVLO Thresholds | VDD: 3.9 V / VBS: 5.5 V - prevents erratic gate drive during power-up or brownout conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5113SD/NOPB | Higher VDD max (20 V), no integrated bootstrap diode, 5-A peak drive | Requires external bootstrap diode; better suited for >15-V systems or higher current demands | Select when system VDD exceeds 15 V or when external diode placement improves thermal management |
| UCC27211D | Same 4-A drive, but no integrated bootstrap diode; 12-V VDD max; different pinout | Needs discrete bootstrap diode and careful layout for high-side bias; preferred in TI ecosystem designs | Choose when using TI C2000 MCU with dedicated gate drive peripherals and existing bootstrap design practices |
Compared with LM5113SD/NOPB and UCC27211D, the FAN2310AMPX offers integrated bootstrap diode and tighter delay matching (≤1 ns vs. ≤2.5 ns), reducing component count and timing uncertainty - especially valuable in compact, high-frequency DC-DC modules where layout parasitics impact reliability.

FAQ
What is the maximum operating frequency supported by the FAN2310AMPX?
The FAN2310AMPX supports switching frequencies up to 2 MHz in practical applications, enabled by its 10-ns propagation delay and ±4-A peak drive strength. At 1 MHz, it reliably drives MOSFETs with up to 50 nC total gate charge. Thermal limits in the DFN8 package define the upper bound under sustained 4-A load, not the driver's intrinsic speed capability. The FAN2310AMPX remains stable and functional across this range without oscillation or timing degradation.
Does the FAN2310AMPX require an external bootstrap diode?
No, the FAN2310AMPX includes an integrated bootstrap diode connected between VDD and VBS, eliminating the need for an external component in standard half-bridge configurations. This integration reduces PCB area, simplifies layout, and improves reliability - especially under transient conditions where discrete diodes may exhibit reverse recovery issues. The FAN2310AMPX maintains proper high-side biasing up to 100 V bootstrap voltage swing without external support.
What is the purpose of the NC pin on the FAN2310AMPX?
The NC (No Connect) pin on the FAN2310AMPX is internally unconnected and serves no electrical function. Per onsemi's recommended layout guidelines, it should remain unconnected or be tied to GND to improve mechanical stability and thermal conduction through the package's exposed pad. It does not affect the operation of the FAN2310AMPX and must not be used as a signal or power terminal.
Can the FAN2310AMPX drive both high-side and low-side GaN FETs?
Yes, the FAN2310AMPX can drive enhancement-mode GaN FETs in both high-side and low-side positions, provided gate drive voltage requirements (typically 0–6 V) fall within its output swing range and gate charge is ≤50 nC. Its fast edge rates and low propagation delay make it suitable for GaN-based topologies like active clamp flyback and totem-pole PFC. The FAN2310AMPX has been validated in reference designs driving GaN devices at 600 kHz with minimal ringing.
How does the FAN2310AMPX handle undervoltage conditions?
The FAN2310AMPX implements dual-rail undervoltage lockout (UVLO): VDD UVLO triggers at 3.9 V (rising) and 3.6 V (falling), while VBS UVLO activates at 5.5 V (rising) and 4.8 V (falling). Both outputs disable simultaneously when either rail drops below threshold, preventing partial turn-on of power switches. This behavior ensures safe startup and fault recovery in the FAN2310AMPX without external supervision circuits.
