3 Description

The TPS22916xx is a small, single channel load

switch utilizing 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 turnon 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 Pull Down is used to keep the ON pin from

floating until system sequencing is complete. Once

Pull Down is disconnected to prevent unnecessary

power loss.

The TPS22916xx is available in a small, space

saving 0.78-mm × 0.78-mm, 0.4-mm pitch, 0.5-mm

height 4-pin Wafer-Chip-Scale (WCSP) package

(YFP). The device is characterized for operation over

a temperature range of –40°C to +85°C.
