DESCRIPTION
The LTC ®1477/LTC1478 protected high side switches provide extremely low RDS(ON) switching with built-in protection against short-circuit and thermal overload conditions. A built-in charge pump generates gate drive higher than the supply voltage to fully enhance the internal NMOS switch. This switch has no parasitic body diode and therefore no current flows through the switch when it is turned off and the output is forced above the input supply voltage. (DMOS switches have parasitic body diodes that bee forward biased under these conditions.) Two levels of protection are provided by...
