L9369-TR Door Drive IC

The YINGHUA L9369-TR is a semiconductor integrated circuit designed to drive door mechanisms. It is intended for engineers and system integrators developing access-control or automation hardware. The LQFP-64 package provides 64 pins for interfacing with motor stages and logic circuits. This component suits new designs requiring a dedicated door-drive solution.

LQFP-64 Package Capacity

The 64-lead LQFP footprint offers sufficient I/O for multi-channel motor control and diagnostic feedback. It handles typical automotive or industrial door-actuator loads within its specified electrical limits. Headroom decreases when driving multiple high-current loads simultaneously or operating at elevated ambient temperatures. Designers must verify thermal dissipation and current ratings against their specific application requirements.

New Condition Availability

Supplied as new stock first listed by the manufacturer in February 2025, the device arrives unused with full parametric compliance. No bundled software, development boards, or evaluation kits are included in the supplier data. Integration relies solely on the manufacturer datasheet for register maps and timing diagrams. Buyers needing pre-flashed firmware or reference designs must source those separately.

Questions about this item

Will the L9369-TR door-drive IC fit on a legacy PCB that uses a 64-pin LQFP footprint?

Yes, the device is packaged in a standard LQFP-64 outline so it matches the same board layout and pin pitch as other 64-pin LQFP parts you may already have.

How can I verify the L9369-TR is operating correctly after soldering it to the board?

Apply the specified supply voltage, activate the door-drive inputs and measure the output pins for the expected logic levels or drive waveforms described in the datasheet.

Does the L9369-TR reel contain only the ICs or are sockets and decoupling capacitors included?

The reel supplies the LQFP-64 ICs only; any sockets, decoupling capacitors or other passive components must be sourced separately.
