Description
The TF2101 is a high voltage, high speed gate driver capable of
driving N-channel MOSFETs and IGBTs in a high-side/low-side
conguration. TF Semiconductor’s high voltage process enables
the TF2101’s high-side to switch to 600V in a bootstrap operation.
The 50ns (max) propagation delay matching between the high
and the low side drivers allows high frequency switching.
The TF2101 logic inputs are compatible with standard TTL and
CMOS levels (down to 3.3V) for easy interfacing with controlling
devices. The driver outputs feature high pulse current buers
designed for minimum driver cross conduction. The low-side
gate driver and logic share a common ground
The TF2101 is available in a space-saving 8-pin SOIC package, an
8-pin PDIP, and a 14-pin SOIC package; the operating temperature
extends from -40°C to +125°C .
