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.
