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 two-thirds and one-third of VCC. 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, 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 –40°C to 125°C.
