FP6863
Slew Rate Limited
Load Switch
Description
Features
The FP6863 is equipped an N-Channel MOSFET
switch which is designed for high-side load-switching
applications, and the device has a 65mΩ typical
RDS-ON and fault current is limited to typically 2.5A.
The FP6863 operates with an input voltage ranging
from 2.0V to 5.5V. It is suitable for both 3V and 5V
systems.
● Input Voltage Range: 2V to 5.5V
● Built-In N-Channel MOSFET: Typically 65mΩ
● Slew Rate Limited Turn On Time 1.5ms (5V)
● Fast Shutdown Load Discharge
● TTL/CMOS Input Logic Level
● Reverse Current Flow Blocking (No Body Diode)
● Output Can Be Forced Higher Than Input
(Off-State)
The FP6863 has a slew rate limited turn-on load
switch and offers a load discharge circuit in
shutdown to rapidly turn off output load when the
switch is disabled. The TTL and CMOS input logic
are compatible for chip enable. It also features an
under voltage lock out (UVLO) which turns the switch
off when an input under-voltage condition exists.
● 1.8V Typical Under-Voltage Lockout (UVLO)
● Low Supply Current:
27μA Typical at Switch On State
0.1μA Typical at Switch Off State
● Hot Plug-In Application (Soft-Start)
● Current Limit Protection
● Current Fold-Back in Short Circuit
● Thermal Shutdown Protection
Other additional features include thermal shutdown
to prevent catastrophic switch failure from high
loading current. Low quiescent current as 27μA in
operation mode and 0.1μA in shutdown mode makes
this device ideal for portable battery-operated
equipment.
Applications
● Digital Camera
● Hot Swap Supply
● Cellular Telephone
● Notebook computer
● Personal Digital Assistant
● Personal Communication Device
The FP6863 is available in low-profile, space-saving
TDFN-8 and SOT-23-5 packages requiring minimum
board space and smallest components.
