description
The TPS1120 incorporates two independent
p-channel enhancement-mode MOSFETs that
have been optimized, by means of the Texas
Instruments LinBiCMOS process, for 3-V or 5-V
power distribution in battery-powered systems. With a maximum V
GS(th)
of –1.5 V and an I
DSS
of only 0.5 µA,
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 MOSFET s have built-in circuitry for 2-kV ESD protection. End equipment for the TPS1 120
includes notebook computers, personal digital assistants (PDAs), cellular telephones, bar-code scanners, and
PCMCIA cards. For existing designs, the TPS1 120D 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, T
J
, from –40°C to 150°C.

The D package is available taped and reeled. Add an R suffix to device
type (e.g., TPS1120DR). The chip form is tested at 25°C.
Caution. This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic
fields. These circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to
MIL-STD-883C, Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than
maximum-rated voltages to these high-impedance circuits.

TPS1120Y chip information
This chip, when properly assembled, displays characteristics similar to the TPS1 120C. Thermal compression
or ultrasonic bonding may be used on the doped aluminum bonding pads. The chip may be mounted with
conductive epoxy or a gold-silicon preform.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
