Procurement Notes

Verify the manufacturer origin carefully, as listings may indicate Sanyo, Rochester Electronics, or other distributors. Confirm the exact suffix 'TLM-E' matches your board design requirements. Check for obsolescence status or lifecycle notices from the current supplier. Ensure the package type is TSSOP-24 to match your footprint. Request original datasheets to confirm electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a dual-channel H-bridge solution is required for brushed DC motors. It is suitable for designs needing low on-resistance to minimize power dissipation. Consider the TSSOP-24 package size constraints during PCB layout. Verify that the 3V logic interface aligns with your microcontroller outputs. Ensure the thermal management strategy accommodates the chip's heat dissipation capabilities under load.

Part Context

This part belongs to the Sanyo (now Microchip) LV84xx series of Bi-CMOS motor drivers. These devices are widely used in consumer electronics for driving small DC motors. The series emphasizes low power consumption and integrated protection features. The LV8404T specifically addresses two-channel control needs in a compact form factor.

Replacement Considerations

Check for direct substitutes within the LV84xx family such as the LV8406T-MPB-E for parallel control variants. Verify pin compatibility and electrical specifications before swapping. Consult Microchip documentation for updated product line replacements if Sanyo branding is discontinued.
