MIC4605-1YM-T5

Overview

The MIC4605-1YM-T5 is a half-bridge MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 5.5 V to 16 V and delivers peak output currents of 1 A for both sourcing and sinking. The device features typical rise and fall times of 20 ns and includes an enable function. It is housed in an 8-SOIC package with a width of 3.90 mm. The component supports TTL logic inputs and functions as a non-inverting driver. It is qualified under the AEC-Q100 standard for automotive applications and operates across a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-current drive capability for N-channel power MOSFETs in half-bridge configurations.
• Incorporates an enable pin to control driver operation and reduce standby power consumption.
• Features fast switching characteristics with symmetric rise and fall times for efficient power stage control.
• Supports independent high-side and low-side outputs for flexible circuit design.

Applications

• Automotive power management systems requiring AEC-Q100 qualified components
• Motor control circuits utilizing half-bridge topologies
• Industrial power conversion stages driving N-channel MOSFETs

Procurement Notes

Verify the specific suffix T5 indicates tape and reel packaging when reviewing distributor listings. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Check current lifecycle status as distribution channels may list obsolete or discontinued stock. Ensure compatibility with your system's logic voltage levels, specifically the 0.8 V and 2.2 V thresholds. Validate that the 1 A peak current meets your MOSFET gate charge requirements at the intended switching frequency.

Selection Notes

Select this component when a single half-bridge driver with 1 A output current is required. It is suitable for designs needing AEC-Q100 qualification in an 8-pin surface-mount package. Consider alternatives if higher current drive or dual-half-bridge integration is needed. Verify that the 5.5 V minimum supply voltage aligns with your system's power rails. Ensure the 20 ns propagation delay fits your timing constraints for the target application.
