The TPS22961 is a small, ultra-low RON, 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 3.5 V and supports a maximum continuous current of 6 A.
The combination of ultra-low RON and high current capability of
the device makes it ideal for driving processor rails with very tight voltage dropout tolerances.
Quick rise time of the device allows for power rails to come up quickly when the device is enabled,
thereby reducing response time for power distribution. The switch can be independently controlled
via the ON terminal, 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 260 Ω pull-down transistor for quick output discharge (QOD)
when the switch is turned off.
The TPS22961 is available in a small, space-saving 3 mm x 3 mm 8-SON package (DNY) with
integrated thermal pad allowing for high power dissipation. The device is characterized for
operation over the free-air temperature range of –40°C to 85°C.
