TPS22906

具有快速输出放电功能的 3.6V，0.5A，90mΩ 负载开关

device is an ultra-small, low ON-state resistance rON load switch with controlled turn on. The device contains a P-channel MOSFET that operates over an input voltage range of 1.0 V to 3.6 V. The switch is controlled by an on/off input ON, which is capable of interfacing directly with low-voltage control signals. A 120-Ω on-chip load resistor is added for output quick discharge when the switch is turned off. TPS22906 is available in a space-saving 4-terminal WCSP with 0.5-mm pitch YZV. The device is characterized for operation over the free-air temperature range of –40°C to 85°C.
