LPW5202
High-Side Load Switch with Over-Current Protection
Features
General Description

⚫
⚫
⚫
2.4V to 6V input voltage range
The LPW5202 is a series of load switches which provide
full protection to systems and loads which may encounter
large current conditions.
Low on-state resistance to 70mΩ
30μA low current consumption
Ultra-low shutdown current (<100nA)
Fixed or adjustable current limit
The device contains a 70mΩ current-limited P-channel
MOSFET which can operate over an input voltage range
from 2.4V to 6V. The current limit is fixed or could be
settable using an external resistor. When the current
reaches the threshold, the device will limit the current to
constant value to prohibit excessive currents from causing
damage. Internally, current is prevented from flowing when
the MOSFET is off and the output voltage is higher than
the input voltage. Switch is controlled by an active-high
logic pin. Thermal shutdown protection is integrated which
shuts off the switch to prevent damage to the part when a
continuous over-current condition causes excessive
heating.
