DESCRIPTION

Low Control Input Thresholds Enable Use of

1.2-V/1.8-V/2.5-V/3.3-V Logic

TPS22901, TPS22902, and TPS22902B are

ultra-small, low ON resistance (r_ON) load switches

with controlled turn on. The devices contain a

P-channel MOSFET that operates over an input

voltage range of 1.0 V to 3.6 V. The switch is

controlled by an on/off input (ON), which is capable of

interfacing directly with low-voltage control signals. In

TPS22902 and in TPS22902B, a 120-Ω on-chip load

resistor is added for output quick discharge when the

switch is turned off.

•

Controlled Slew Rate to Avoid Inrush Currents

–

TPS22901 and TPS22902: 40-µs t_r

TPS22902B: 220-µs t_r

•

ESD Performance Tested Per JESD 22

–

2000-V Human-Body Model

(A114-B, Class II)

–

1000-V Charged-Device Model (C101)

TPS22901, TPS22902, and TPS22902B are available

in a space-saving 4-terminal WCSP with 0.4-mm

pitch (YFP). The devices are characterized for

operation over the free-air temperature range of

–40°C to 85°C.
