3 Description
The TPS22941/2/3/4/5 load switches provide
protection to systems and loads in high-current conditions. The devices contain a 0.4-Ω current-
limited P-channel MOSFET that can operate over an
input voltage range of 1.62 V to 5.5 V. Current is
prevented from flowing when the MOSFET is off. The
switch is controlled by an on/off input (ON), which is
capable of interfacing directly with low-voltage control
signals. The TPS22941/2/3/4/5 includes thermal
shutdown protection that prevents damage to the
device when a continuous over-current condition
causes excessive heating by turning off the switch.
These devices provide an integrated, robust solution
to provide current limiting the output current to a safe
level by switching into a constant-current mode when
the ouptut load exceeds the current-limit threshold.
The OC logic output asserts low during overcurrent, undervoltage, or overtemperature conditions. These
additional features make the TPS22941/2/3/4/5 an
ideal solution for applications where current limiting is
necessary.
This family of devices are available in a SC70-5
(DCK) package. It is characterized for operation over
the free-air temperature range of –40°C to 85°C.
