The TPS22910A, TPS22912C, and TPS22913B/C are small, low rONload switches with controlled turn on. The device contains a P-channel MOSFET that can operate over an input voltage range of 1.4 V to 5.5 V. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage GPIO control signals. The TPS22910A, TPS22912C, and TPS22913B/C devices provide reverse current protection in ON and OFF states.

The TPS22916xx is a small, single channel load switch using a low leakage P-Channel MOSFET for minimum power loss. Advanced gate control design supports operating voltages as low as 1 V with minimal increase in ON-resistance and power loss. Multiple timing options are available to support various system loading conditions. For heavy capacitive loads, the slow turn-on timing in the C version minimizes the inrush current. In cases with light capacitive loads, the fast timing in the B version reduces required wait time. The switch ON state is controlled by a digital input that is capable of interfacing directly with low-voltage control signals. Both Active High and Active Low (L) versions are available. When power is first applied, a smart pulldown is used to keep the ON pin from floating until system sequencing is complete. AFter the ON pin is deliberately driven high (≥VIH), the smart pulldown is disconnected to prevent unnecessary power loss.
