The TPS22991I is a small, low RON,
single channel load switch with controlled slew rate. The device contains an N-channel
MOSFET that operates over an input voltage range of 1.0V to 5.5V and supports a maximum
continuous current of 3A. The switch is controlled by an on and off input, which is capable
of interfacing directly with low-voltage control signals.
For space constrained, battery powered
applications, the device is suitable due to its small size and low RON. The wide
input voltage range of the switch applies to many different voltage rails. The controlled
rise time of the device greatly reduces inrush current caused by large bulk load
capacitances, thereby reducing or eliminating power supply droop. The TPS22991I further
reduces the total solution size by integrating a 150Ω pulldown resistor for quick output
discharge (QOD) when the switch is turned off.
The TPS22991I is available in a small, space
saving 0.85mm × 0.75mm, 0.4mm pitch, 4-pin UQFN package. The device is characterized for
operation over the free-air temperature range of –55°C to +125°C.
