TPS22960 具有控制启动和快速输出放电功能的低输入电压双路负载开关

The TPS22960 is a small low-rON dual load switch with controlled turn on. The devices contain two P-channel MOSFETs that can operate over an input voltage range of 1.62 V to 5.5 V. Each switch is controlled by an on/off input (ON1 and ON2), which is capable of interfacing directly with low-voltage control signals. In TPS22960 a 85-Ω on-chip load resistor is added for output quick discharge when switch is turned off.

The rise time (slew-rate) of the device is internally controlled in order to avoid inrush current and can be slowed down if needed using the SR pin: TPS22960 feature a 75 µs rise time with the SR pin tied to ground and 660 µs with the SR pin tied to high.

The TPS22960 is available in a space-saving 8-pin µQFN package and in an 8-pin SOT package
