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
the pin is deliberately driven high (>V_IH), the Smart
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.
