MC33883DWR2

Overview

The MC33883DWR2 is a four-channel half-bridge gate driver IC manufactured by NXP USA Inc., housed in a 20-SOIC surface-mount package. It provides independent drive for N-channel MOSFETs with peak output currents of 1A source and sink. The device operates on a supply voltage range of 5.5V to 28V, supporting high-side bootstrap voltages up to 55V. Logic thresholds are defined at 0.8V (VIL) and 2V (VIH). Typical rise and fall times are 80ns each. It functions within a junction temperature range of -40°C to 150°C.

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm the specific suffix 'DWR2' matches the required 20-SOIC package variant. Check RoHS compliance status as indicated in official documentation, noting potential regulatory restrictions. Validate lead times and availability given the product's lifecycle status. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet.

Selection Notes

Select this component when designing systems requiring four isolated half-bridge drivers for N-channel MOSFETs. It is suitable for automotive environments demanding high junction temperature tolerance up to 150°C. Consider the 55V bootstrap voltage limit for high-side applications. Verify that the 1A peak current meets the gate charge requirements of the target power devices. Ensure the 5.5V minimum supply voltage aligns with the system's power architecture.
