DESCRIPTION

TPS22903 is an ultra-small, low r_ONdual load switch with controlled turn on. The device contains a P-channel

MOSFET that can operate over an input voltage range of 1.1 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.

TPS22903 is available in a space-saving 4-terminal WCSP 0.4-mm pitch (YFP). The device is characterized for

operation over the free-air temperature range of –40°C to 85°C.

(2) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI

website at www.ti.com.

(3) The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following character to

designate the wafer fab/assembly site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, • = Pb-free).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
