Texas Instruments  TPS22916BYFPR

The TPS22916xx is a small, single channel load switch using a low leakage P-ChannelMOSFET for minimum power loss. Advanced gate control design supports operating voltages as low as 1V with minimal increase in ON-Resistance and power loss.

Multiple timing options are available to support various system loading conditions. Forheavy capacitive loads, the slow turnon timing in the C version minimizes the inrush current. Incases with light capacitive loads, the fast timing in the B version reduces required waittime.

The switch ON state is controlled by a digital input that is capable of interfacingdirectly with low-voltage control signals. Both Active High and Active Low (L) versions areavailable. When power is first applied, a Smart Pull Down is used to keep the ON pin from floatinguntil system sequencing is complete. Once the ON pin is deliberately driven high(≥VIH), the Smart Pull Down is disconnected to prevent unnecessary powerloss.

The TPS22916xx is available in a small, space saving 0.74-mm × 0.74-mm, 0.4-mm pitch,0.5-mm height 4-pin Wafer-Chip-Scale (WCSP) package (YFP). The device is characterized foroperation over a temperature range of –40°C to +85°C.
