Overview
The TPS22966DPUT is a dual-channel load switch designed by Texas Instruments, offering high efficiency and controlled turn-on for power management in various electronic devices. This component features two N-channel MOSFETs that can operate over an input voltage range of 0.8 V to 5.5 V and support a maximum continuous current of 6 A per channel. Each switch is independently controlled by separate on and off inputs, enabling direct interface with low-voltage control signals. The device is packaged in a small, space-saving 2-mm × 3-mm 14-pin WSON (DPU) package with an integrated thermal pad for high power dissipation and is characterized for operation over a temperature range of –40°C to +105°C.
