D, P, AND PW PACKAGES (TOP VIEW) 1IN1 1IN2 2IN1 2IN2 description The TPS28xx series of dual high-speed MOSFET drivers are capable of delivering peak currents of 2 A into highly capacitive loads. This performance is achieved with a design that inherently minimizes shoot-through current and consumes an order of magnitude less supply current than competitive products. 1 8 2 7 3 6 4 5 GND 1OUT VCC 2OUT TPS2815 . . .

The regulator output can power other circuitry, provided power dissipation does not exceed package limitations. When the regulator is not required, REG_IN and REG_OUT can be left disconnected or both can be connected to VCC or GND. The TPS2814 and the TPS2815 have 2-input gates that give the user greater flexibility in controlling the MOSFET. The TPS2814 has AND input gates with one inverting input. The TPS2815 has dual-input NAND gates. TPS28xx series drivers, available in 8-pin PDIP, SOIC, and TSSOP packages and as unmounted ICs, operate over a ambient temperature range of –40°C to 125°C.

DRIVERS SLVS132D – NOVEMBER 1995 – REVISED NOVEMBER 1997 APPLICATION INFORMATION The TPS2811, TPS2812 and TPS2813 circuits each contain one regulator and two MOSFET drivers. The regulator can be used to limit VCC to between 10 V and 13 V for a range of input voltages from 14 V to 40 V, while providing up to 20 mA of dc drive. The TPS2814 and TPS2815 both contain two drivers, each of which has two inputs. The TPS2811 has inverting drivers, the TPS2812 has noninverting drivers, and the TPS2813 has one inverting and one noninverting driver. The TPS2814 is a dual 2-input AND driver with one inverting input on each driver, and the TPS2815 is a dual 2-input NAND driver. These MOSFET drivers are capable of supplying up to 2.1 A or sinking up to 1.9 A (see Figures 15 and 16) of instantaneous current to n-channel or p-channel MOSFETs. The TPS2811 family of MOSFET drivers have very fast switching times combined with very short propagation delays. These features enhance the operation of today’s high-frequency circuits. The CMOS input circuit has a positive threshold of approximately 2/3 of VCC, with a negative threshold of 1/3 of VCC, and a very high input impedance in the range of 109 Ω. Noise immunity is also very high because of the Schmidt trigger switching. In addition, the design is such that the normal shoot-through current in CMOS (when the input is biased halfway between VCC and ground) is limited to less than 6 mA. The limited shoot-through is evident in the graphs in Figures 17 and 18. The input stage shown in the functional block diagram better illustrates the way the front end works. The circuitry of the device is such that regardless of the rise and/or fall time of the input signal, the output signal will always have a fast transition speed; this basically isolates the waveforms at the input from the output. Therefore, the specified switching times are not affected by the slopes of the input waveforms. The basic driver portion of the circuits operate over a supply voltage range of 4 V to 14 V with a maximum bias current of 5 µA. Each driver consists of a CMOS input and a buffered output with a 2-A instantaneous drive capability. They have propagation delays of less than 30 ns and rise and fall times of less than 20 ns each. Placing a 0.1-µF ceramic capacitor between VCC and ground is recommended; this will supply the instantaneous current needed by the fast switching and high current surges of the driver when it is driving a MOSFET. The output circuit is also shown in the functional block diagram. This driver uses a unique combination of a bipolar transistor in parallel with a MOSFET for the ability to swing from VCC to ground while providing 2 A of instantaneous driver current. This unique parallel combination of bipolar and MOSFET output transistors provides the drive required at VCC and ground to guarantee turn-off of even low-threshold MOSFETs. Typical bipolar-only output devices don’t easily approach VCC or ground. The regulator, included in the TPS2811, TPS2812 and TPS2813, has an input voltage range of 14 V to 40 V. It produces an output voltage of 10 V to 13 V and is capable of supplying from 0 to 20 mA of output current. In grounded source applications, this extends the overall circuit operation to 40 V by clamping the driver supply voltage (VCC) to a safe level for both the driver and the MOSFET gate. The bias current for full operation is a maximum of 150 µA. A 0.1-µF capacitor connected between the regulator output and ground is required to ensure stability. For transient response, an additional 4.7-µF electrolytic capacitor on the output and a 0.1-µF ceramic capacitor on the input will optimize the performance of this circuit. When the regulator is not in use, it can be left open at both the input and the output, or the input can be shorted to the output and tied to either the VCC or the ground pin of the chip. 14 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TPS2811, TPS2812, TPS2813, TPS2814, TPS2815 DUAL HIGH-SPEED MOSFET DRIVERS SLVS132D – NOVEMBER 1995 – REVISED NOVEMBER 1997 APPLICATION INFORMATION matching and paralleling connections Figures 21 and 22 show the delays for the rise and fall time of each channel. As can be seen on a 5-ns scale, there is very little difference between the two channels at no load. Figures 23 and 24 show the difference between the two channels for a 1-nF load on each output. There is a slight delay on the rising edge, but little or no delay on the falling edge. As an example of extreme overload, Figures 25 and 26 show the difference between the two channels, or two drivers in the package, each driving a 10-nF load. As would be expected, the rise and fall times are significantly slowed down. Figures 28 and 29 show the effect of paralleling the two channels and driving a 1-nF load. A noticeable improvement is evident in the rise and fall times of the output waveforms. Finally, Figures 30 and 31 show the two drivers being paralleled to drive the 10-nF load and as could be expected the waveforms are improved. In summary, the paralleling of the two drivers in a package enhances the capability of the drivers to handle a larger load. Because of manufacturing tolerances, it is not recommended to parallel drivers that are not in the same package. TPS2811 1 50 Ω Regulator + 8 2 7 3 6 0.1 µF VCC 4.7 µF Output 1 nF 4 5 Figure 19.

The MOSFETs that were tested range in size from Hex-1 to Hex-4, although the TPS28xx family is only recommended for Hex-3 or below. The test circuit is shown in Figure 32. The layout rules observed in building the test circuit also apply to real applications. Decoupling capacitor C1 is a 0.1-µF ceramic device, connected between VCC and GND of the TPS2811, with short lead lengths. The connection between the driver output and the MOSFET gate, and between GND and the MOSFET source, are as short as possible to minimize inductance. Ideally, GND of the driver is connected directly to the MOSFET source. The tests were conducted with the pulse generator frequency set very low to eliminate the need for heat sinking, and the duty cycle was set to turn off the MOSFET when the drain current reached 50% of its rated value. The input voltage was adjusted to clamp the drain voltage at 80% of its rating. As shown, the driver is capable of driving each of the Hex-1 through Hex-3 MOSFETs to switch in 20 ns or less. Even the Hex-4 is turned on in less than 20 ns. Figures 45, 46 and 47 show that paralleling the two drivers in a package enhances the gate waveforms and improves the switching speed of the MOSFET. Generally, one driver is capable of driving up to a Hex-4 size. The TPS2811 family is even capable of driving large MOSFETs that have a low gate charge.

The bill of materials is provided in Table 1. The converter operates over an input range from 5.5 V to 12 V and has a 3.3-V output capable of supplying 3 A continuously and 5 A during load surges. The converter achieves an efficiency of 90.6% at 3 A and 87.6% at 5 A. Figures 49 and 50 show the power switch switching performance. The output ripple voltage waveforms are documented in Figures 54 and 55. The TPS2812 drives both the power switch, Q2, and the synchronous rectifier, Q1. Large shoot-through currents, caused by power switch and synchronous rectifier remaining on simultaneously during the transitions, are prevented by small delays built into the drive signals, using CR2, CR3, R11, R12, and the input capacitance of the TPS2812. These delays allow the power switch to turn off before the synchronous rectifier turns on and vice versa. Figure 51 shows the delay between the drain of Q2 and the gate of Q1; expanded views are provided in Figures 52 and 53.
