SI82521AB-IM1

Isolators - Gate Drivers Overview

The SI82521AB-IM1 is a dual-channel, galvanically isolated gate driver featuring high-side and low-side outputs in a DFN-14 package. It provides symmetric drive with a peak output current of 4.0 A and supports a maximum supply voltage (VDD) of 20 V. The device offers a propagation delay of 75 ns and operates within a temperature range of -40°C to +125°C. It includes under-voltage lockout (UVLO) for reliable operation and delivers 2.5 kVrms isolation capability.

Isolators - Gate Drivers Feature Summary

Provides symmetrical high-side and low-side gate drive signals through integrated digital isolation.
Features robust transient immunity and under-voltage lockout mechanisms for stable switching performance.
Delivers high peak output current to efficiently drive power switches in demanding environments.

Isolators - Gate Drivers Applications

Isolated gate drive applications for power electronics
Motor control systems requiring high-side and low-side driving
Industrial inverters and converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IM1 corresponds to the DFN-14 surface-mount package configuration. Confirm that the 2.5 kVrms isolation rating meets system safety requirements. Ensure the 20 V maximum supply voltage aligns with the target power stage logic levels. Check for RoHS compliance status and automotive qualification if applicable to the end application.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 4.0 A peak current is required. It is suitable for designs needing 2.5 kVrms isolation in a compact DFN-14 footprint. Consider the 75 ns propagation delay for timing-sensitive applications. Compare against higher-speed or higher-current alternatives if system demands exceed these specifications.

Isolators - Gate Drivers Part Context
