FEATURES
DESCRIPTION
The TPS22930 is a small, low R
ON
load switch with
• Integrated Single Channel Load Switch
controlled turn on. The device contains a P-channel
• Ultra Small CSP-4 Package (0.9mm × 0.9mm,
MOSFET that can operate over an input voltage
0.5mm pitch)
range of 1.4V to 5.5V. The switch is controlled by an
• Input Voltage Range: 1.4V to 5.5V
on/off input (ON), which is capable of interfacing
directly with low-voltage control signals. The
