产品概述
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.
