FEATURES
DESCRIPTION
The TPS22924C is a small, ultra-low rON load switch
Integrated Single Load Switch
with
controlled
turn
on.
The
devices
contain
Input Voltage: 0.75 V to 3.6 V
N-channel MOSFETs that can operate over an input
Ultra-Low ON Resistance
voltage range of 0.75 V to 3.6 V. An integrated
charge pump biases the NMOS switch to achieve a
– rON = 18.3 m at VIN = 3.6 V
minimum
switch
ON
resistance.
The
switch
is
– rON = 18.5 m at VIN = 2.5 V
controlled by an on/off input (ON), which is capable of
– rON = 19.6 m at VIN = 1.8 V
interfacing directly with low-voltage control signals.
– rON = 19.4 m at VIN = 1.2 V
A 1250-
Ω on-chip load resistor is added for output
– rON = 20.3 m at VIN = 1.0 V
quick discharge when switch is turned off. The rise
time of the device is internally controlled to avoid
– rON = 22.7 m at VIN = 0.75 V
inrush current. The TPS22924C features a rise time
Ultra Small CSP-6 package
of 800
s at 3.6 V.
0.9 mm x 1.4 mm, 0.5-mm Pitch
The
TPS22924C
is
available
in
an
ultra-small
2-A Maximum Continuous Switch Current
space-saving
6-pin
