BM61S41RFV-CE2

Isolators - Gate Drivers Overview

The BM61S41RFV-CE2 is a single-channel isolated gate driver manufactured by ROHM Semiconductor, designed for high-speed switching applications. It features magnetic coupling technology to provide galvanic isolation with a voltage rating of 3750 Vrms. The device delivers a peak output current of 4 A and supports supply voltages ranging from 4.5 V to 5.5 V on the input side and 16 V to 24 V on the output side. Key electrical parameters include a maximum propagation delay of 65 ns, rise and fall times of 15 ns, and a minimum input pulse width of 60 ns. It operates within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Isolators - Gate Drivers Feature Summary

• Utilizes magnetic coupling technology for reliable galvanic isolation between input and output circuits.
• Provides active Miller clamping functionality to prevent false triggering during high dv/dt events.
• Includes under-voltage lockout (UVLO) protection functions on both the input and output power supply sides.
• Qualified for automotive applications in accordance with the AEC-Q100 standard.

Isolators - Gate Drivers Applications

• Driving Silicon Carbide (SiC) power devices
• High-side and low-side gate control in half-bridge configurations
• Industrial motor drive systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix CE2 against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure that the design accounts for the required input and output supply voltage ranges. Confirm compliance with functional safety requirements if the application demands FS supportive certification. Check for any pending UL certifications relevant to your region.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity and fast switching speeds are required for wide-bandgap semiconductors. The 4 A output current capability suits medium-power SiC MOSFETs. Consider the 10-SSOP-BW package size for PCB layout constraints. Evaluate the need for separate input and output supplies given the distinct voltage ranges supported by the driver.

Isolators - Gate Drivers Part Context

This part belongs to the BM61S41 series of isolated gate drivers from ROHM Semiconductor. It is specifically engineered for automotive and industrial environments where reliability under harsh conditions is critical. The series supports evaluation boards such as the BM61S41RFV-EVK001 and EVK002 for testing SiC device performance.

Isolators - Gate Drivers Replacement Considerations

The BM61S41RFV-C is listed as a related product but is marked as non-recommended for new designs. Verify if the CE2 suffix offers updated packaging or qualification status compared to older variants before substitution.
