STMicroelectronics L6386ED Environmental and export classification status description

The STMicroelectronics L6386ED is a dual high-voltage gate driver designed to drive various types of power MOSFETs and IGBTs. It operates at high voltages and is suitable for use in power electronics applications, including motor control, power converters, and inverters. Functions - High and Low Side Driving: Capable of driving both high-side and low-side MOSFETs in a half-bridge configuration. - Bootstrap Circuit: Utilizes a bootstrap capacitor to drive the high-side gate. - Level Shifting: Provides level shifting for high-side and low-side applications. - Dead Time Control: Has feature for adjustable dead time to prevent shoot-through. - Undervoltage Lockout (UVLO): Protects the driver when the supply voltage is too low. Applications - Motor Drives: Suitable for driving BLDC motors or stepper motors. - Power Converters: Used in DC-DC converters, PFC circuits, and resonance converters. - Inverters: Regularly used in solar inverters, UPS, and other power conversion applications. - Industrial Controls: Employs in various industrial automation systems requiring reliable gate driving. Alternative Parts Some alternative gate drivers to the L6386ED include: - L6385: Similar half-bridge driver with slightly different electrical ratings. - L5981: A more integrated driver with additional functionalities. - MIC4426: Another high-speed MOSFET driver but with different specifications. Embedded Modules While the L6386ED itself is not an embedded module, it is often found in integrated modules or PCB designs, where it may be paired with: - Power MOSFETs or IGBTs for the target application. - Microcontrollers to generate PWM signals for the gate driver. - Filtering capacitors and inductors for EMI mitigation and power management.
