Q & A
- What is the input voltage range of the FPF2701MPX?
The input voltage range is from 2.8 V to 36 V.
- How is the current limit adjusted on the FPF2701MPX?
The current limit can be adjusted from 0.4 A to 2.0 A through the ISET pin.
- What protection features does the FPF2701MPX offer?
The device offers under-voltage lockout (UVLO), thermal shutdown, and over-current protection.
- How does the ON/OFF control work on the FPF2701MPX?
The ON pin is active LOW, and pulling it continuously to LOW holds the switch in the ON state. The switch moves into the OFF state when the ON pin is pulled HIGH.
- What happens during an overload condition on the FPF2701MPX?
The device latches off the load if the overload condition persists beyond the blanking time. The load remains off unless the ON pin is toggled or the input voltage cycles through UVLO.
- Is the FPF2701MPX ESD protected?
Yes, the device is ESD protected above 2000 V HBM.
- What are the available packages for the FPF2701MPX?
The device is available in 8-lead MLP 3x3 mm and SO8 packages.
- Is the FPF2701MPX still in production?
No, the FPF2701MPX is obsolete and no longer manufactured.
- What are some typical applications for the FPF2701MPX?
Typical applications include motor drives, digital cameras, consumer electronics, industrial equipment, computing, hard disk drives, and telecom equipment.
- How does the thermal shutdown protection work on the FPF2701MPX?
The device shuts off if the junction temperature exceeds 140°C to prevent excessive power dissipation.
