1 Features
•1 Input Voltage Range: 0.8 V to 5.5 V • Integrated Dual-Channel Load Switch • On-Resistance
– RON = 16 mΩ at VIN = 5 V (VBIAS = 5 V) – RON = 16 mΩ at VIN = 3.6 V (VBIAS = 5 V) – RON = 16 mΩ at VIN = 1.8 V (VBIAS = 5 V) • 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-, 1.8-, 2.5-, and 3.3-V Logic • Configurable Rise Time • Quick Output Discharge (QOD) (Optional) • SON 14-Pin Package With Thermal Pad • ESD Performance Tested per JESD 22 – 2-kV HBM and 1-kV CDM
3 Description
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 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.
