Preliminary
SINGLE-CHANNEL,
ULTRA-Low RESISTANCE
LOAD SWITCH
DESCRIPTION
The UTC ULS5422 device is a small, ultra-low RON,
single-channel load switch with controlled turnon. The device
contains an N-channel MOSFET that can operate over an input
voltage range of 0.8V to 5.5V and can support a maximum
continuous current of 4A. The switch is controlled by an on/off input
(ON), which can interface directly with low-voltage control signals.
In the UTC ULS5422, a 225Ω pulldown resistor is added for quick
output discharge when the switch is turned off.
The UTC ULS5422 is available in a small, space-saving 2mm ×
2mm 8pin WSON package (DSG) with integrated thermal pad
allowing for high power dissipation.
FEATURES
* Integrated Single-Channel Load Switch
* Input Voltage Range: 0.8 V~5.5V
* Low RON Resistance
RON=22mΩ at VIN=5V (VBIAS=5V)
RON=22mΩ at VIN=3.6V (VBIAS=5V)
RON=22mΩ at VIN=1.8V (VBIAS=5V)
* Low Quiescent Current (50µA)
* Low Control Input Threshold Enables Use of 1.2V, 1.8V, 2.5V,
and 3.3V Logic
* Configurable Rise Time
* Quick Output Discharge (QOD)
