open-in-new Find other Load switches


The TPS22966 is a small, low RON, dual-channel load switch with controlled turnon. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.8 V to 5.5 V and can support a maximum continuous current of 6 A per channel. Each switch is independently controlled by an on and off input (ON1 and ON2), which can interface directly with low-voltage control signals. In TPS22966, a 220-Ω on-chip load resistor is added for quick-output discharge when switch is turned off.

The TPS22966 is available in a small, space-saving 2-mm × 3-mm 14-SON package (DPU) with integrated thermal pad allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of –40°C to +105°C.

document-generic User guide

The TPS22966EVM allows the user to apply an input voltage of (0.8 V-5.5 V) to each of two inputs under different loading conditions (0-6 A). Each switch is independently controlled by an on/off input (ON1, ON2), which is capable of interfacing directly with lowvoltage GPIO control signals. Output (...)
