VLA567-21R

Overview

The VLA567-21R is a half-bridge gate driver IC manufactured by Powerex Inc. It features inverting and non-inverting input types with typical rise and fall times of 400ns and 300ns, respectively. The device operates within a temperature range of -20°C to 70°C and utilizes through-hole mounting.

Feature Summary

• Supports both inverting and non-inverting input signal configurations for flexible control logic integration.

Applications

• Half-bridge power converter circuits
• Motor drive systems requiring isolated gate control
• Industrial power supply designs

Procurement Notes

Verify the specific suffix '21R' against official Powerex documentation to confirm pinout and electrical characteristics, as variations exist within the VLA567 series. Ensure compatibility with your PCB footprint and thermal management requirements before finalizing procurement.

Selection Notes

Select this component when a half-bridge topology with specific rise/fall time constraints (400ns/300ns) is required. Consider the operating temperature range of -20°C to 70°C for environmental suitability. Verify if inverting/non-inverting inputs meet the control interface needs.

Part Context

The VLA567 series includes variants like VLA567-01R and VLA567-11R, which may differ in isolation or additional features such as desaturation protection. The VLA567-21R specifically denotes a configuration with defined timing parameters and input types distinct from other suffixes in the family.

Replacement Considerations

Cross-reference with VLA567-01R or VLA567-11R only if datasheet specifications for input type, timing, and package match exactly. Verify functional equivalence with other Powerex half-bridge drivers before substitution.
