The L638xE is a versatile, high-voltage gate driver family of devices that can be used in all types of applications where high-voltage shifted control is necessary.
The document serves as an application guide for the STMicroelectronics L638xE family of versatile, high-voltage gate drivers. Developed using BCD offline technology, these devices operate with voltage rails up to 600 V and are designed to drive both power MOSFETs and IGBTs in high- and low-side configurations.
| Operating voltage rails | up to 600 V |
|---|---|
| Driver current capability (source) | 400 mA |
| Driver current capability (sink) | 650 mA |
It replaces the external bootstrap diode by using a high voltage DMOS synchronously driven with the low-side gate driver.
The family includes the L6384E, L6385E, L6386E, L6387E, and L6388E devices.
