The TPS1100 is a single P-channel enhancement-mode MOSFET. The device has been optimized for 3-V or 5-V power distribution in battery-powered systems by means of Texas Instruments LinBiCMOS^TM process. With a maximum V_GS(th) of -1.5 V and an I_DSS of only 0.5 uA, the TPS1100 is the ideal high-side switch for low-voltage, portable battery-management systems where maximizing battery life is a primary concern. The low r_DS(on) and excellent ac characteristics (rise time 10 ns typical) make the TPS1100 the logical choice for low-voltage switching applications such as power switches for pulse-width-modulated (PWM) controllers or motor/bridge drivers.

The ultrathin thin shrink small-outline package or TSSOP (PW) version with its smaller footprint and reduction in height fits in places where other P-channel MOSFETs cannot.
