3 Description

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 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

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 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 for operation over

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