• 6-A Maximum Continuous Switch Current per Channel

• Low Quiescent Current – 80 µA (Both Channels) – 60 µA (Single Channel)

• Low Control Input Threshold Enables Use of

1.2-V, 1.8-V, 2.5-V, and 3.3-V Logic

• Configurable Rise Time

• Quick Output Discharge (QOD)

• SON 14-Pin Package With Thermal Pad

• ESD Performance Tested per JESD 22 – 2-kV HBM and 1-kV CDM

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/off input (ON1 and ON2), which can interface directly with low-voltage control signals. In TPS22966, a 220Ω 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.
