EL7155CSZ

Gate Driver Overview

The EL7155CSZ is a high-speed, non-inverting gate driver IC designed for driving IGBTs and MOSFETs. It features a dual-channel configuration with independent high-side and low-side outputs in an 8-SOIC package. The device operates on a single supply voltage ranging from 4.5V to 16.5V. It provides peak output currents of 3.5A for both sourcing and sinking. Typical propagation delays are characterized by rise times of 14.5ns and fall times of 15ns. The component supports logic input levels of 0.8V (VIL) and 2.4V (VIH). It is rated for junction temperatures between -40°C and +125°C.

Gate Driver Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to confirm packaging type and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel or tube configuration. Cross-reference the datasheet revision date to validate electrical parameters and pinout assignments before finalizing procurement specifications.

Gate Driver Selection Notes

Select this component when a non-inverting, dual-channel driver is required for IGBT or MOSFET applications. The 3.5A output current rating suits moderate-power switching frequencies. Verify that the 4.5V to 16.5V supply range aligns with the system's available rail voltages. Confirm that the 8-SOIC footprint fits the target PCB layout constraints.

Gate Driver Part Context

The EL7155CSZ belongs to the Renesas EL7155 series of gate drivers. This family includes variants such as the EL7155CS and EL7155CS-T13. The 'CSZ' suffix typically denotes a lead-free, RoHS-compliant version in an SOIC-8 package. It serves as a direct replacement for older non-RoHS versions like the EL7155CS.

Gate Driver Replacement Considerations

The EL7155CSZ is listed as a direct replacement for the obsolete EL7155CS. Verify pin compatibility and electrical specifications when substituting other members of the EL7155 family.
