3 Description
The TPS22969 is a small, ultra-low R_ON, single
channel load switch with controlled turn on. The
device contains an N-channel MOSFET that can
operate over an input voltage range of 0.8 V to 5.5 V
and can support a maximum continuous
current of 6 A.
The combination of ultra-low R_ON and high current
capability of the device makes it ideal for driving
processor rails with very tight voltage dropout
tolerances. The controlled rise time of the device
greatly reduces inrush current caused by large bulk
load capacitances, thereby reducing or eliminating
voltage droop on the power supply. The switch can
be independently controlled via the ON pin, which is
capable of interfacing directly with low-voltage control
signals originating from microcontrollers or low
voltage discrete logic. The device further reduces the
total solution size by integrating a 224-Ω pull-down
resistor for quick output discharge (QOD) when the
switch is turned off.
The TPS22969 is available in a small 3.00 mm x 3.00
mm SON-8 package (DNY). The DNY package
integrates a thermal pad which allows for high power
dissipation in high current and high temperature
applications. The device is characterized for
operation over the free-air temperature range of
–40°C to 105°C.
