UCC27528DSDT

Gate Driver Overview

The UCC27528DSDT is a dual low-side gate driver manufactured by Texas Instruments, designed for driving IGBTs and N-channel MOSFETs. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 5 A for both sourcing and sinking. The device features non-inverting logic inputs with typical rise and fall times of 7 ns and 6 ns, respectively. Housed in an 8-SON (3x3 mm) package, it supports a junction temperature range from -40°C to +140°C and includes negative voltage handling on the input pins.

Gate Driver Feature Summary

• Dual independent low-side channel configuration for simultaneous control of two power switches
• High-speed switching capability with nanosecond-level propagation delays
• Robust input stage capable of tolerating negative voltage transients
• CMOS-compatible logic interface for direct connection to microcontrollers

Gate Driver Applications

• Industrial motor drives requiring precise low-side switching
• Power supply topologies utilizing discrete MOSFET or IGBT stages
• Inverter circuits in renewable energy systems
• Automotive power electronics applications

Gate Driver Procurement Notes

Verify the specific suffix DSDT corresponds to the WSON-8 package and tape-and-reel orientation required for your assembly process. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements against your manufacturing environment standards. Ensure the ordering quantity matches the manufacturer's standard reel size to avoid cut-tape premiums if applicable.

Gate Driver Selection Notes

Select this component when high peak current drive is needed for low-side configurations without the complexity of high-side bootstrap circuits. The wide operating temperature range makes it suitable for harsh industrial environments. Consider the small footprint of the 8-SON package for space-constrained designs. Verify that the input signal levels are compatible with the CMOS logic threshold requirements.

Gate Driver Part Context

This part belongs to the UCC2752x series of gate drivers from Texas Instruments, which focuses on high-performance, low-side driving solutions. The series is engineered for efficiency and speed in power conversion applications. The DSDT variant specifically denotes the surface-mount WSON packaging format, distinguishing it from through-hole or other surface-mount options available in the broader product line.

Gate Driver Replacement Considerations

Check for pin-to-pin compatible alternatives within the same family, such as the UCC27527, ensuring functional equivalence in drive strength and package dimensions before substitution.
