IVCR1801ASR

Gate Driver Overview

The IVCR1801ASR is a single-channel, high-speed low-side gate driver designed for efficient and safe driving of MOSFETs, IGBTs, and wide-bandgap power switches. It features a peak source current of 4A and a peak sink current of 8A. The device exhibits a typical propagation delay of less than 20ns, supporting switching frequencies in the hundreds of kHz range. It operates with a wide VDD supply range up to 24V and includes under-voltage lockout protection. The input logic is compatible with both TTL and CMOS levels, accepting inputs between 800mV and 1.2V at low state. Quiescent current is specified at 190uA, with a fall time of 30ns.

Gate Driver Procurement Notes

Verify the specific suffix 'ASR' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications, as variations may exist within the IVCR1801 family. Ensure that the selected component meets the required industrial reliability standards if deployed in automotive or harsh environments. Cross-reference the ordering information with authorized distributors to confirm RoHS compliance status and moisture sensitivity level ratings prior to procurement.

Gate Driver Selection Notes

Select this component when a compact, high-current low-side driver is required for driving SiC, GaN, or standard silicon power devices. The choice is driven by the need for sub-20ns propagation delay and high peak currents in space-constrained designs utilizing the SOT-23-6 package. It serves as a suitable alternative to international equivalents like the UCC27511, particularly where local supply chain resilience and cost-effectiveness are prioritized alongside comparable electrical performance metrics.

Gate Driver Part Context

The IVCR1801ASR belongs to the IVCR1801 series of general-purpose gate drivers developed by Inventchip. This series is engineered to replace established industry parts such as the UCC27511, offering similar functionality with localized manufacturing advantages.
