Texas Instruments TPS2295x-Q1 Single Channel Load Switches

Texas Instruments TPS2295x-Q1 Single Channel Load Switches come with a controlled turn-on. The devices contain an N-channel MOSFET that can support a maximum continuous current of 5A and operate over an input voltage range of 0.7V to 5.7V.

The integrated Power Good (PG) threshold and adjustable Undervoltage Lockout (UVLO) provide robust power sequencing and voltage monitoring. The adjustable rise-time control of the device significantly reduces inrush current for a wide variety of bulk load capacitances. This feature reduces or eliminates power supply droop. The switch is independently controlled by an on-and-off input (EN), capable of interfacing directly with low-voltage control signals. To quickly discharge the output when the switch is disabled, a 15Ω on-chip load is integrated into the device. The enhanced Quick Output Discharge (QOD) remains active shortly after power is removed from the device to finish discharging the output.

The Texas Instruments TPS2295x-Q1 are available in small, space-saving 10-SON packages with an integrated thermal pad, allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of -40°C to +125°C.
