TPS22903 超小型低输入电压低功耗 rDS(ON) 负载开关
TPS22903 描述
The TPS22903 and TPS22904 are ultra-small, low rON single channel load switches with controlled turn on. The device contains a P-channel MOSFET that can operate over an input voltage range of 1.1 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. In TPS22903, a 85- on-chip load resistor is added for output quick discharge when switch is turned off.
TPS22903 and TPS22904 are available in a space-saving 4-terminal WCSP 0.4-mm pitch (YFP). The devices are characterized for operation over the free-air temperature range of –40°C to 85°C
