Procurement Notes
Verify the specific suffix E2 against official ROHM documentation to confirm compliance requirements and pinout compatibility. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm that the intended operating voltage and thermal environment remain within the specified 4.5V to 16V and -40C to 105C limits. Cross-reference the datasheet for any updates regarding RoHS status or recommended soldering profiles prior to final procurement decisions.
Selection Notes
Select this component when a dedicated driver for single-phase BLDC fans is required. The 1.2A output current capability suits moderate load applications. The wide operating temperature range allows deployment in demanding environments. Consider the VSON-10 footprint for PCB layout constraints. Verify that the PWM frequency range matches the system controller's output capabilities to ensure stable motor operation without excessive switching losses.
