Overview
The L6494LDTR, produced by STMicroelectronics, is a high voltage, high and low-side 2 A gate driver. This device is manufactured using the BCD6 “OFF-LINE” technology and is designed as a single-chip half-bridge gate driver for N-channel power MOSFETs or IGBTs. The high-side (floating) section can withstand a voltage rail up to 500 V, with a transient withstand voltage of 600 V. The logic inputs are CMOS/TTL compatible down to 3.3 V, facilitating easy interfacing with microcontrollers or DSPs.
