What would recommend me you? High side gate driver floating supply. Also, if this is not possible as Respawned Fluff saidcould I use any workaround to drive at 3. Micropower startup V CC supply current.

Now I’m reviewing the second one. UV-mode C T pin pulldown current.

Switching Time Waveform Ir21513. Care should be taken to avoid output switching conditions where the V S node flies inductively below ground by. Low Voltage Supply Characteristics. The IR is a self-oscillating driver. In order to optimize your browsing experience Infineon uses cookies.

Allowable offset voltage slew rate. C unless otherwise specified.

Gate Driver Output Characteristics. Noise immunity has been improved significantly, both by lowering the peak. Excellent latch immunity ir215311 all inputs and outputs. High voltage floating supply return.

Constant LO, HO pulse widths at startup. I’m doing a very compact design where I only have a V power supply and a 3. Steady state high side floating supply offset voltage. Low-level R T output voltage. I really appreciate your comment, and after reading it, I see clearly that is better to find another gate driver, as using it will end in a bigger, expensive and ineficient implementation of my idea.


Micropower startup V BS supply current. R T pin current. V CC undervoltage lockout Hysteresis.
