TPS22968 - Texas Instruments

TPS22968 Ultra-Low Resistance Load Switch

The TPS22968x is a small, ultra-low RON, dualchannel load switch with controlled turn on. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.8 to 5.5 V and can support a maximum continuous current of 4 A per channel. Each switch is independently controlled by an on and off input (ON1 and ON2), which is capable of inte.

Features

•1 Integrated Dual Channel Load Switch
• Input Voltage Range: 0.8 V to 5.5 V
• VBIAS Voltage Range: 2.5 V to 5.5 V
  – Ideal for 1S Battery Configuration
• Ultra-Low RON Resistance
  – RON = 27 mΩ at VIN = 5 V (VBIAS = 5 V)
  – RON = 25 mΩ at VIN = 3.3 V (VBIAS = 5 V)
  – RON = 25 mΩ at VIN = 1.8 V (VBIAS = 5 V)
• 4-A Maximum Continuous Switch Current per Channel
• Low Quiescent Current
  – 55 µA at VBIAS = 5 V (Both Channels)
  – 55 µA at VBIAS = 5 V (Single Channel)
• Low Control Input Threshold Enables Use of 1.2-,1.8-, 2.5-, 3.3-V Logic
• Configurable Rise Time(1)
• Quick Output Discharge (QOD)(2) (Op.
