Texas Instruments TPS22916xx Ultra-Low Leakage Load Switch

Texas Instruments TPS22916xx Ultra-Low Leakage Load Switch is a single-channel load switch with an integrated P-Channel MOSFET for minimum power loss. The TPS22916xx features an advanced gate control design, enabling it to support operating voltages as low as 1V with minimal increase in ON-Resistance and power loss. The TPS22916xx is offered multiple timing options to support various system loading conditions. For heavy capacitive loads, the slow turnon timing in the C version minimizes the inrush current. In cases with light, capacitive loads, the fast timing in the B version reduces the required wait time.

The ON state of the TPS22916xx Load Switch is controlled by a digital input capable of interfacing directly with low-voltage control signals. Both Active High and Active Low (L) versions are available. When power is applied, a Smart Pull Down keeps the ON pin from floating until system sequencing is complete. Once the ON pin is deliberately driven high (≥VIH), the Smart Pull Down is disconnected to prevent unnecessary power loss.

The TPS22916xx is available in a compact 0.78mm2 Wafer-Chip-Scale Package (WCSP), ideal for space-constrained applications.
