Supply Current versus Supply Voltage APPLICATIONS INFORMATION Description Output Stage The MC34151 is a dual inverting high speed driver specifically designed to interface low current digital circuitry with power MOSFETs. This device is constructed with Schottky clamped Bipolar Analog technology which offers a high degree of performance and ruggedness in hostile industrial environments. Each totem pole Drive Output is capable of sourcing and sinking up to 1.5 A with a typical ‘on’ resistance of 2.4 at 1.0 A. The low ‘on’ resistance allows high output currents to be attained at a lower VCC than with comparative CMOS drivers. Each output has a 100 k pulldown resistor to keep the MOSFET gate low when VCC is less than 1.4 V. No over current or thermal protection has been designed into the device, so output shorting to VCC or ground must be avoided. Parasitic inductance in series with the load will cause the driver outputs to ring above VCC during the turn−on transition, and below ground during the turn−off transition. With CMOS drivers, this mode of operation can cause a destructive output latchup condition. The MC34151 is immune to output latchup. The Drive Outputs contain an internal diode to VCC for clamping positive voltage transients. When operating with VCC at 18 V, proper power supply bypassing must be observed to prevent the output ringing from exceeding the maximum 20 V device rating. Negative output transients are clamped by the internal NPN pullup transistor. Since full supply voltage is applied across Input Stage The Logic Inputs have 170 mV of hysteresis with the input threshold centered at 1.67 V. The input thresholds are insensitive to VCC making this device directly compatible with CMOS and LSTTL logic families over its entire operating voltage range. Input hysteresis provides fast output switching that is independent of the input signal transition time, preventing output oscillations as the input thresholds are crossed. The inputs are designed to accept a signal amplitude ranging from ground to VCC. This allows the output of one channel to directly drive the input of a second channel for master−slave operation. Each input has a 30 k pulldown resistor so that an unconnected open input will cause the associated Drive Output to be in a known high state. http://onsemi.com 5 MC34151, MC33151 gate charge information on their data sheets. Figure 18 shows a curve of gate voltage versus gate charge for the ON Semiconductor MTM15N50. Note that there are three distinct slopes to the curve representing different input capacitance values. To completely switch the MOSFET ‘on’, the gate must be brought to 10 V with respect to the source. The graph shows that a gate charge Qg of 110 nC is required when operating the MOSFET with a drain to source voltage VDS of 400 V. the NPN pullup during the negative output transient, power dissipation at high frequencies can become excessive. Figures 20, 21, and 22 show a method of using external Schottky diode clamps to reduce driver power dissipation. Undervoltage Lockout V GS , GATE−TO−SOURCE VOLTAGE (V) An undervoltage lockout with hysteresis prevents erratic system operation at low supply voltages. The UVLO forces the Drive Outputs into a low state as VCC rises from 1.4 V to the 5.8 V upper threshold. The lower UVLO threshold is 5.3 V, yielding about 500 mV of hysteresis. Power Dissipation Circuit performance and long term reliability are enhanced with reduced die temperature. Die temperature increase is directly related to the power that the integrated circuit must dissipate and the total thermal resistance from the junction to ambient. The formula for calculating the junction temperature with the package in free air is: where: TJ = TJ = TA = PD = RJA = TA + PD (RJA) Junction Temperature Ambient Temperature Power Dissipation Thermal Resistance Junction to Ambient 16 MTM15N50 ID = 15 A TA = 25°C 12 8.0 8.9 nF 4.0 2.0 nF 0 0 There are three basic components that make up total power to be dissipated when driving a capacitive load with respect to ground. They are: where: PD = PQ = PC = PT = 120 160 The flat region from 10 nC to 55 nC is caused by the drain−to−gate Miller capacitance, occurring while the MOSFET is in the linear region dissipating substantial amounts of power. The high output current capability of the MC34151 is able to quickly deliver the required gate charge for fast power efficient MOSFET switching. By operating the MC34151 at a higher VCC, additional charge can be provided to bring the gate above 10 V. This will reduce the ‘on’ resistance of the MOSFET at the expense of higher driver dissipation at a given operating frequency. The transition power dissipation is due to extremely short simultaneous conduction of internal circuit nodes when the Drive Outputs change state. The transition power dissipation per driver is approximately: ICCL (1−D) + ICCH (D) The capacitive load power dissipation is directly related to the load capacitance value, frequency, and Drive Output voltage swing. The capacitive load power dissipation per driver is: where: 80 Qg, GATE CHARGE (nC) PC(MOSFET) = VC Qg f ICCL = Supply Current with Low State Drive Outputs ICCH = Supply Current with High State Drive Outputs D = Output Duty Cycle PC = VOH = VOL = CL = f= 40 Qg VGS The capacitive load power dissipation is directly related to the required gate charge, and operating frequency. The capacitive load power dissipation per driver is: The quiescent power supply current depends on the supply voltage and duty cycle as shown in Figure 17. The device’s quiescent power dissipation is: where: CGS = Figure 18.

VCC (VOH − VOL) CL f High State Drive Output Voltage Low State Drive Output Voltage Load Capacitance frequency Switching time characterization of the MC34151 is performed with fixed capacitive loads. Figure 14 shows that for small capacitance loads, the switching speed is limited by transistor turn−on/off time and the slew rate of the internal nodes. For large capacitance loads, the switching speed is limited by the maximum output current capability of the integrated circuit. When driving a MOSFET, the calculation of capacitive load power PC is somewhat complicated by the changing gate to source capacitance CGS as the device switches. To aid in this calculation, power MOSFET manufacturers provide http://onsemi.com 6 MC34151, MC33151 LAYOUT CONSIDERATIONS optimum drive performance, it is recommended that the initial circuit design contains dual power supply bypass capacitors connected with short leads as close to the VCC pin and ground as the layout will permit. Suggested capacitors are a low inductance 0.1 F ceramic in parallel with a 4.7 F tantalum. Additional bypass capacitors may be required depending upon Drive Output loading and circuit layout. Proper printed circuit board layout is extremely critical and cannot be over emphasized. High frequency printed circuit layout techniques are imperative to prevent excessive output ringing and overshoot. Do not attempt to construct the driver circuit on wire−wrap or plug−in prototype boards. When driving large capacitive loads, the printed circuit board must contain a low inductance ground plane to minimize the voltage spikes induced by the high ground ripple currents. All high current loops should be kept as short as possible using heavy copper runs to provide a low impedance high frequency path.

Rg will decrease the MOSFET switching speed. Schottky diode D1 can reduce the driver’s power dissipation due to excessive ringing, by preventing the output pin from being driven below ground. 3 The MC34151 greatly enhances the drive capabilities of common switching regulators and CMOS/TTL logic devices.
