PI5PD2061/65
70mΩ Current-Limited, Power-Distribution Switches
Description
Features
The PI5PD2061/65 is an integrated 70mΩ N-channel
70mΩ High-Side MOSFET
MOSFET power switches for self-powered and bus-
1.5A Continuous Current
powered Universal Series Bus (USB) applications. The
Thermal and Short-Circuit Protection
devices are equipped with charge pump circuitry to drive
Accurate Current Limit (2.3A typ.)
the internal MOSFET switch. The switch’s low RDS(on),
Operating Range: 2.7V to 5.5V
70mΩ meets USB voltage drop requirements. This
0.6ms Typical Rise Time
power-distribution switch is designed to set current limit
Under-Voltage Lockout
at 2.3A typically.

Note:
(1)Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
(2)All voltages are with respect to GND.
