MIC4607-1YML-T5

Overview

The MIC4607-1YML-T5 is a three-phase half-bridge MOSFET gate driver manufactured by Microchip Technology. It integrates six independent drivers within a single package, supporting high-voltage applications with a maximum bootstrap voltage of 108 V. The device operates on a supply voltage range of 5.25 V to 16 V and delivers a peak output current of 1 A for both sourcing and sinking. Key timing parameters include rise and fall times of 20 ns, with maximum propagation delay and dead time set at 75 ns and 35 ns respectively. It functions in non-inverting or inverting configurations and withstands operating temperatures from -40°C to +125°C.

Feature Summary

• Integrates six independent half-bridge drivers for complete three-phase control
• Includes adaptive dead-time generation to prevent shoot-through conditions
• Supports high-side driving up to 108 V via bootstrap architecture
• Features TTL-compatible logic inputs for direct microcontroller interfacing

Applications

• Three-phase motor drives and inverters
• Brushless DC (BLDC) motor control systems
• Industrial power conversion equipment
• High-voltage switching applications requiring phase isolation

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet before procurement. Confirm that the component status aligns with project lifecycle requirements, as availability may vary. Ensure all electrical specifications, particularly voltage ratings and thermal limits, match the target application design constraints. Cross-reference ordering information with official Microchip documentation to avoid counterfeit or obsolete stock.

Selection Notes

Select this component when designing three-phase systems requiring integrated protection and high-speed switching. Evaluate the 1 A drive strength against the total gate charge of the target MOSFETs to ensure adequate switching performance. Consider the 108 V bootstrap limit for high-side applications. Verify that the 5.25 V minimum supply voltage is compatible with the system's logic levels and power rails.
