onsemi PowerMUX Load Switches
onsemi PowerMUX Load Switches are Dual-Input Single Output (DISO) load switches with two sets of slew-rate controlled low on-resistance MOSFET switches. The slew rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage drop on the input rails.
Features
- FPF1320/1:
- DISO load switches
