TF2101, High-Side and Low-Side Gate Driver

Product Type: Gate Driver
Current Status: Advance Info

Product Overview
The TF2101 is a high voltage, high speed gate driver capable of driving N-channel MOSFETs and IGBTs in a high-side/low-side configuration. Telefunken’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 buffers designed for minimum driver cross conduction.
The low-side gate driver and logic share a common ground to enable a space-saving 8-pin SOIC package and an 8-pin PDIP.
The TF2101 operates over an extended -40°C to +125°C temperature range.
