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 (tr and tf = 14 ns typ) are

obtained with the use of BiCMOS outputs. Typical

threshold switching voltages are 2/3 and 1/3 of

VCC. The design inherently minimizes shootthrough

current.

A regulator is provided on TPS2816 through TPS2819 devices to allow operation with supply inputs between

14 V and 40 V. The regulator output can be used to power other circuits, provided power dissipation does not

exceed package limitations. If the regulator is not required, VDD (the regulator input) should be connected to

VCC. 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 μA 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 –40C to 125C.
