Texas Instruments TPS22907YZTT

Description
The TPS22907 is an ultra-small, low Ron load switch with controlled turn-on. It contains a P-channel MOSFET that operates over an input voltage range of 1.1 V to 3.6 V. The switch is controlled by an on/off input (ON), which can interface directly with low-voltage control signals.

Features
Low input voltage: 1.1 V to 3.6 V
Ultra-low ON-state resistance:
TON = 44 mΩ at VIN = 3.6 V
TON = 50 mΩ at VIN = 2.5 V
TON = 58 mΩ at VIN = 1.8 V
TON = 83 mΩ at VIN = 1.2 V
1-A maximum continuous switch current
Quiescent current < 1 μA
Shutdown current < 1 μA
Low control input thresholds enable use of low-voltage logic
Controlled slew rate to avoid inrush currents
ESD performance tested per JESD 22:
3000-V human-body model (A114-B, Class II)
1000-V charged-device model (C101)
Ultra-small four-terminal wafer chip scale package (WCSP): 0.9 mm x 0.9 mm
