description

The TPS28xx single-channel high-speed MOS-

FET drivers are capable of delivering peak

currents of up to 2 A into highly capacitive loads.

High switching speeds (t

and t

= 14 ns typ) are

obtained with the use of BiCMOS outputs. Typical

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

. The design inherently minimizes shoot-

through 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, V

(the regulator input) should be connected to

. 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.

SLVS160C – FEBRUARY 1997 – REVISED OCTOBER 2002 APPLICATION INFORMATION MOSFETs are voltage-driven devices that require very little steady-state drive current. However, the large input capacitance (200 pF to 3000 pF or greater) of these devices requires large current surges to reduce the turn-on and turn-off times.

SLVS160C – FEBRUARY 1997 – REVISED OCTOBER 2002 APPLICATION INFORMATION The on-board series regulator supplies approximately 20 mA of current at 11.5 V, some of which can be used for external circuitry, providing the power dissipation rating for the driver is not exceeded. When using the on-board series regulator, an electrolytic output capacitor of 4.7 µF or larger is recommended. Although not required, a 0.
