C 40 c to 125 c ambient-temperature operating range ? highly resistant to latch-ups description the tps28xx single-channel high-speed mosfet drivers are capable of delivering peak currents of up to 2 a into highly capacitive loads. high switching speeds (t r and t f = 14 ns typ) are obtained with the use of bicmos outputs. typical threshold switching voltages are two-thirds and one-third of v cc . the design inherently minimizes shoot-through current. a regulator is provided on tps2816 through tps2819 devices to allow operation with supply inputs between 14v and 40v. the regulator output can be used to power other circuits, provided power dissipation does not exceed package limitations. if the regulator is not required, v dd (the regulator input) should be connected to v cc . the tps2816 and tps2817 input circuits include an active pullup circuit to eliminate the need for an external resistor when using open-collector pwm controllers. the tps2818 and tps2819 are identical to the tps2816 and tps2817, except that the active pullup circuit is omitted. the tps2828 and tps2829 are identical to the tps2818 and tps2819, except that the internal voltage regulator is omitted, allowing quiescent current to drop to less than 15 a when the inputs are high or low. the tps28xx series devices are available in 5-pin sot-23 (dbv) packages and operate over an ambient temperature range of C 40 c to 125 c. 1 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. copyright ? 2005 C 2011, texas instruments incorporated products conform to specifications per the terms of the texas instruments standard warranty. production processing does not necessarily include testing of all parameters. 3 2 1 4 5 in v cc v dd out tps2816, tps2817 tps2818, tps2819 dbv package (top view) gnd 3 2 1 4 5 in v cc nc out dbv package (top view) gnd tps2828, tps2829 nc no internal connection
