(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
DESCRIPTION/ORDERING INFORMATION
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
shoot-through current.

SGDS039–FEBRUARY 2008
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 –55°C to 125°C.

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. The TPS2816 series of high-speed drivers can supply up to 2 A to a MOSFET, greatly
reducing the switching times. The fast rise times and fall times and short propagation delays allow for operation
in today's high-frequency switching converters.
In addition, MOSFETs have a limited gate-bias voltage range, usually less than 20 V. The TPS2816 series of
drivers extends this operating range by incorporating an on-board series regulator with an input range up to 40 V.
This regulator can be used to power the drivers, the PWM chip, and other circuitry, providing the power
dissipation rating is not exceeded.
When using these devices, care should be exercised in the proper placement of the driver, the switching
MOSFET, and the bypass capacitor. Because of the large input capacitance of the MOSFET, the driver should
be placed close to the gate to eliminate the possibility of oscillations caused by trace inductance ringing with the
gate capacitance of the MOSFET. When the driver output path is longer than approximately 2 inches, a resistor
in the range of 10 Ω should be placed in series with the gate drive as close as possible to the MOSFET. A
ceramic bypass capacitor is also recommended to provide a source for the high-speed current transients that the
MOSFET requires. This capacitor should be placed between VCC and GND of the driver (see Figure 20 and
Figure 21).

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
0.1 µF ceramic capacitor on the input of the regulator can help suppress transient currents (see Figure 22).
When not used, the regulator should be connected to VCC. Grounding VDD will result in destruction of the
regulator.

Figure 22. Boost Application
The TPS2816 and TPS2818 drivers include active pullup circuits on the inputs to eliminate the need for external
pullup resistors when using controllers with open-collector outputs (such as the TL5001). The TPS2817 and
TPS2819 drivers have standard CMOS inputs providing a total device operating current of less than 50 µA. All
devices switch at standard CMOS logic levels of approximately 2/3 VCC with positive-going input levels, and
approximately 1/3 VCC with negative-going input levels. Being CMOS drivers, these devices will draw relatively
large amounts of current (Approximately 5 mA) when the inputs are in the range of one-half of the supply
voltage. In normal operation, the driver input is in this range for a very short time. Care should be taken to avoid
use of very low slew-rate inputs, used under normal operating conditions. Although not destructive to the device,
slew rates slower than 0.1 V/µs are not recommended.
The BiCMOS output stage provides high instantaneous drive current to rapidly toggle the power switch, and very
low drop to each rail to ensure proper operation at voltage extremes.
Low-voltage circuits (less than 14 V) that require very low quiescent currents can use the TPS2828 and
TPS2829 drivers. These drivers use typically 0.2 µA of quiescent current (with inputs high or low). They do not
have the internal regulator or the active pullup circuit, but all other specifications are the same as for the rest of
the family.
2.5-V/3.3-V, 3-A Application
Figure 23 illustrates the use of the TPS2817 with a TL5001 PWM controller and a TPS1110 in a simple
step-down converter application. The converter operates at 275 kHz and delivers either 2.5 V or 3.3 V
(determined by the value of R6) at 3 A (5 A peak) from a 5-V supply. The bill of materials is provided in Table 1.
