Fault-protected overvoltage switch employing isolated transistor tubs |
摘要 |
An integrated-circuit (IC) chip formed with a fault-protected switch comprising three MOS transistors in series. Each transistor is placed in a corresponding tub of the IC chip. Each of these tubs is electrically isolated from all other sections of the IC chip, so that the MOS transistors are isolated from one another and from the chip voltage supplies.
