LF2101N High-Side / Low-Side Gate Driver Features Description F loating high-side driver in bootstrap operation to The LF2101N is a high voltage, high speed gate driver 600V capable of driving N-channel MOSFETs and IGBTs in a high- side/low-side configuration. The high voltage process D rives two N-channel MOSFETs or IGBTs in high-side/ enables the LF2101Ns high-side to switch to 600V in a low-side configuration bootstrap operation. The 50ns (max) propagation delay Outputs tolerant to negative transients matching between the high and the low side drivers allows Wide low-side gate driver and logic supply: high frequency switching. 10V to 20V LF2101N logic inputs are compatible with standard TTL Logic inputs CMOS and TTL compatible and CMOS levels (down to 3.3V) for easy interfacing (down to 3.3V) with controlling devices. The driver outputs feature high Schmitt triggered logic inputs with internal pull down pulse current buffers designed for minimum driver cross ( low-side Under Voltage Lockout (UVLO) for V conduction. The low-side gate driver and logic share a CC driver ) common ground Space-saving SOIC(N)-8 package available LF2101N is oeff red in a space-saving 8-pin SOIC package o o Extended temperature range:-40 C to +125 C op er ating ove r th e e x te nde d temp er ature r ange of -40C to +125C .
