| Need a fast industrial output driver IC, high-side mosfet. |

| Leicester:
Hi everyone! I'm designing a rotary encoder for a CNC spindle. My sensor outputs A/B/Ref in differential signals which I process into TTL. For the output I need a high-side switch that can switch 24v at very fast speeds (<10uS)... Currently on my prototype there is a ITS41K0S-ME-N which is way too slow, have not thought about that when I initialy designed the circuit. I use this "smart" thingy because it is protected against practically everything. Do you know anything similar but much faster? I'm struggling... Thanks for any help! /Leic |

You'll probably have to build it yourself. All the "smart" high-side switches I know are pretty slow. |

Almost all intelligent, automotive/industrial high side switches that need few external parts, such as the ITS41K0S you considered, have output delay times on the order of 100 µs – at least, as of a few years ago, when I looked. If you can find room for a few more passives, the Infineon (International Rectifier) AUIPS7221RTRL is a couple orders of magnitude faster. Mouser is the first distributor I could find that currently has them in stock. |

How about the LTC7003? https://www.analog.com/en/products/ltc7003.html |
