Texas Instruments TPS22963/64 Load Switch is a small, ultra-low RON load switch with a controlled turn-on. The device has a low RDSON N-Channel MOSFET that can operate over an input voltage range of 1V to 5.5V. It can also switch currents up to 3A. An integrated charge pump biases the NMOS switch to achieve a low switch ON-Resistance. The switch is controlled by an on/off input (ON), capable of interfacing directly with low-voltage GPIO control signals. The TPS22963/64 device’s rise time is internally controlled to avoid inrush current.
The TPS22963/64 provides reverse current protection. When the power switch is disabled, the device will not allow the flow of current to the input side of the switch. This feature is only active when the device is disabled, allowing for intentional reverse current (when the switch is enabled) for some applications. The Texas Instruments TPS22963/64 is available in a space-saving 6-pin WCSP package. It is characterized for operation over the free air temperature range of –40°C to 85°C.
