Texas Instruments TPS229xx Load Switches
Texas Instruments TPS229xx Load Switches are small, low RON, single channel load switches with a controlled slew rate. Each device contains either an N-channel or P-channel MOSFET and is controlled by an on/off input, which is capable of interfacing directly with low-voltage control signals.
The small size and low RON of the TPS229xx Load Switches make them ideal for use in space constrained, battery-powered applications. The wide input voltage range of the switches makes them a versatile solution for many different voltage rails. The controlled rise time of these devices greatly reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating power supply droop. Certain TPS229xx Load Switches further reduce the total solution size by integrating a pull-down resistor for quick output discharge (QOD) when the switch is turned off.
