The TPS22914/15 is a small, low RON, single channel load switch
with controlled slew rate. The device contains an N-channel MOSFET that can operate over an input
voltage range of 1.05 V to 5.5 V and can support a maximum continuous current of 2 A. The switch is
controlled by an on and off input, which is capable of interfacing directly with low-voltage
The small size and low RON makes the device ideal for being used
in space constrained, battery powered applications. The wide input voltage range of the switch
makes it a versatile solution for 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 TPS22915 further reduces the total solution size by integrating
a 143-Ω pull-down resistor for quick output discharge (QOD) when the switch is turned off.
The TPS22914/15 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 the free-air temperature range of –40°C to +105°C.
