Low-Input Voltage Current Limited Load Switch With Shut-Off And Auto-Restart Features

The TPS22941 TPS22942 TPS22943 TPS22944 TPS22945 load switches provide protection to systems and loads in high-current conditions. The devices contain a 400-mΩ 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 TPS2294x includes thermal shutdown protection that prevents damage to the device when a continuous over-current condition causes excessive heating by turning off the Switch When the Switch current reaches the maximum limit, the TPS22941 2/3/4/5 operates in a constant-current mode to prohibit excessive currents from causing damage. TPS22941 3 has a current limit of 40 mA and TPS22942/4/5 has a current limit of 100 mA. For the TPS22941 2/5, if the constant current condition still persists after 10ms, these parts shut off the Switch and pull the fault signal pin (OC) low. The TPS22941 2/5, have an auto-restart feature that turns the Switch on again after 80 ms if the ON pin is still active. A current limit condition on the TPS22943 and on the TPS22944 immediately pull the fault signal pin low (OC pin) and the part remains in the constant-current mode until the Switch current falls below the current limit. The TPS2294x is available in a SC70-5 (DCK) package. It is characterized for operation over the free-air temperature range of –40°C to 85°C. By Texas Instruments
