description
The TPS1120 incorporates two independent
p-channel enhancement-mode MOSFETs that
have been optimized, by means of the Texas
Instruments LinBiCMOSE process, for 3-V or 5-V
power distribution in battery-powered systems. With a maximum VGS(th) of –1.5 V and an IDSS of only 0.5 mA,
the TPS1120 is the ideal high-side switch for low-voltage portable battery-management systems, where
maximizing battery life is a primary concern. Because portable equipment is potentially subject to electrostatic
discharge (ESD), the MOSFETs have built-in circuitry for 2-kV ESD protection. End equipment for the TPS1120
includes notebook computers, personal digital assistants (PDAs), cellular telephones, bar-code scanners, and
PCMCIA cards. For existing designs, the TPS1120D has a pinout common with other p-channel MOSFETs in
small-outline integrated circuit SOIC packages.
The TPS1120 is characterized for an operating junction temperature range, TJ, from –40°C to 150°C.
