G5178A/G5178B/G5178C
Ultra Small, Low Input Voltage, Low RON, Load
Switch
Global Mixed-mode Technology
Features
General Description
„ Low input voltage 1.0V to 3.6V
The G5178A G5178B and G5178C are .ultra-small, low
ON resistance (Ron) load switches with controlled turn
on. The devices contain a P-channel MOSFET that
operates over an input voltage range 1.2V to 3.6V. The
switch is controlled by an on/off input (EN), which is
capable of in interfacing directly with low-voltage control
signals. In G5178B and G5178C a 120Ω on-chip load
resistor is added for output quick discharge when the
switch is turned off.
„ Ultra low RON
- RON =78mΩ at VIN=3.6V
- RON =93mΩ at VIN=2.5V
- RON =109mΩ at VIN=1.8V
- RON =146mΩ at VIN=1.2V
„ 500mA maximum continuous operating current.
„ Ultra low quiescent current : 82nA at VIN=1.8V
„ Ultra low sundown current : 44nA at VIN=1.8V
„ Low Control Input Thresholds Enable Use of
1.2V/1.8V/2.5V/3.3V Logic
„ Controlled Slew Rate to Avoid Inrush Currents
G5178A and G5178B: 40-us tr
G5178C: 220-us tr
„ Micro-power shutdown current
„ 0.8mmX0.8mm 4-pin, pin pitch 0.4mm WLCSP
Package
