Overview
The L6498DTR, produced by STMicroelectronics, is a high voltage, single chip half-bridge gate driver designed for N-channel power MOSFETs or IGBTs. It is manufactured using the BCD6 “OFF-LINE” technology, which enables it to handle high voltage applications. The device features a high-side (floating) section that can withstand a DC voltage rail up to 500 V, with a transient withstand voltage of 600 V. The logic inputs are CMOS/TTL compatible, making it easy to interface with control units such as microcontrollers or DSPs.
