The low on-resistance p-channel Trench FET is tailored for use as a load switch. The n-channel, with an external resistor, can be used as a level-shift to drive the p-channel load-switch. The n-channel MOSFET has internal ESD protection and can be driven by logic signals as low as 1.5-V. The Si1040X operates on supply lines from 1.8 to 8 V, and can drive loads up to 0.43 A.

The integrated n-channel level-shift device saves space by reducing external ponents. The slew rate is set externally so that rise-times can be tailored to different load types. - Minimum R1 value should be at least 10 x R2 to ensure Q1 turn-on. Document Number: 71809 S-20008- Rev.
