ELECTRICAL CHARACTERISTICS: POWER SWITCH Over recommended operating junction temperature range, VI(IN1) = VI(IN2) = 5.5 V, and RILIM = 400 Ω, unless otherwise noted. TPS2114A TPS2115A PARAMETER TEST CONDITIONS MIN TYP MAX MIN TYP MAX UNIT TJ = 25°C, IL = 500 mA, VI(IN1) = VI(IN2) = 5.0 V 120 140 84 110 m Ω TJ = 25°C, IL = 500 mA, VI(IN1) = VI(IN2) = 3.3 V 120 140 84 110 m Ω TJ = 25°C, IL = 500 mA, VI(IN1) = VI(IN2) = 2.8 V 120 140 84 110 m Ω Drain-source on-state rDS(on) (1) resistance (INx −OUT) TJ = 125°C, IL = 500 mA, VI(IN1) = VI(IN2) = 5.0 V 220 150 m Ω TJ = 125°C, IL = 500 mA, VI(IN1) = VI(IN2) = 3.3 V 220 150 m Ω TJ = 125°C, IL = 500 mA, VI(IN1) = VI(IN2) = 2.8 V 220 150 m Ω (1) The TPS211xA can switch a voltage as low as 1.5 V as long as there is a minimum of 2.8 V at one of the input power pins. In this specific case, the lower supply voltage has no effect on the IN1 and IN2 switch on-resistances. Copyright © 2004–2012, Texas Instruments Incorporated 3 |
