The high-speed, single-channel low-side driver SGM48521 is designed to drive GaN FETs and logic level MOSFETs. Application areas include LiDAR, time of flight, facial recognition, and power converters using low-side drivers. The SGM48521 provides 7A source and 6A sink output current capability. Split output configuration allows individual turn-on and turn-off time optimization depending on FET. Package and pinout with minimum parasitic inductances reduce the rise and fall time and limit the ringing. Additionally, the 2.2ns propagation delay with minimized tolerances and variations allows efficient operation at high frequencies.
The driver has internal under-voltage lockout and over-temperature protection against overload and fault events.
The SGM48521 is available in Green WLCSP-0.88×1.28-6B and TDFN-2×2-6AL packages.
