Overview
The TPS22960DCNR is a low-input voltage, dual-load switch with controlled turn-on, manufactured by Texas Instruments. This device features two P-channel MOSFETs that can operate over an input voltage range of 1.62V to 5.5V. Each switch is independently controlled by on/off inputs (ON1 and ON2), which can interface directly with low-voltage control signals. The TPS22960DCNR is designed for applications requiring low ON-state resistance and controlled output rise times to avoid inrush current.
