It uses a digital isolator for digital I/O. The block labeled “Control (µC)” gets power from the DC-DC converter and is referenced to the output of the SSPC. This block contains an amplifier to gain up the voltage developed across the sense resistor. It also contains a microcontroller with on-board timers, A/D converter, clock generator and independent watchdog 2 timer. The microcontroller implements a precision I t protection curve as well as an Instant Trip function to protect the wiring and to protect itself. It performs all of the functions of multiple analog comparators and discrete logic in one high-reliability component. The code programmed in the microcontroller acquires the output of the internal A/D converter, squares the result and applies it to a simulated RC circuit. It checks the output of the simulated circuit to determine whether or not to trip (turn off the power MOSFETs). Because the microcontroller simulates an analog RC circuit, the SSPC has ‘thermal memory’. That is, it trips faster if there had been current flowing prior to the overload than if there hadn’t been current flowing. This behavior imitates thermal circuit breakers and better protects the application’s wiring since the wiring cannot take as much an overload if current had been flowing prior to the overload. The watchdog timer operates from its own internal clock so a failure of the main clock will not stop the watchdog timer. The code programmed in the microcontroller will periodically reset the watchdog timer preventing it from timing out. If the code malfunctions for any reason, the watchdog timer is not reset and it times out. When the watchdog timer times out, it resets the microcontroller. Since the code is designed to detect levels and not edges, the output of the module, and therefore the output of the SPDP10D375, immediately reflects the command on its input. The Control block also has the ability for the user to adjust the current rating by varying the trip point with a 2 resistor between the “I t TRIP ADJ” pin and the “LOAD” pin, to adjust the Instant Trip current level with a resistor between the “INSTANT TRIP ADJ” pin and the “LOAD” pin. See Equation (1) to select the appropriate resistor for adjusting the current rating. See Equation 2 to select the appropriate resistor for adjusting the Instant Trip current. 2 Select RI2T to program the current rating between 3A and 10A. Please notice the actual I t trip level is 2 between 115% and 145% of the programed current according to the I T trip curve. Equation (1) Select RINST to program the instant trip level between 400% and 700% of the rated current. Equation (2) Note: I0 is rated current for the SSPC unit 10A. © 2011 Sensitron Semiconductor 221 West Industry Court Deer Park, NY 11729-4681 Phone (631) 586 7600 Fax (631) 242 9798 www.sensitron.com [email protected] SENSITRON PROPRIETARY Page 8 SENSITRON ___ SEMICONDUCTOR SPDP10D270 SPDP10D375 PART NUMBER: SPDP10D270/SPDP10D375 DATASHEET 5223, Rev. The Power MOSFETs used in the SPDPXXD375 Series have been selected for very low Rds (on) and result in low voltage drop and low power dissipation. In most applications, the SPDPXXD375 will be operated at 50 – 60% of rated current to provide a safety margin. As can be seen in Table 4, when the SPDP10D375 is operated at 6 Amps, 60% of rated current, it dissipates less than 1.3 Watt at room temperature. No heat sinking is required for this condition. However, if the SPDP10D375 is to be operated at maximum rating and/or at elevated temperatures, the dissipation can exceed 4 Watts and heat sinking is required. Some heat sink can be accomplished by adding copper area to the “LINE” and “LOAD” pins, a heat sink can be epoxy attached to the surface of the module or a flat copper or aluminum heat sink can be sandwiched between the SPDP10D375 and the printed circuit board using a thermal pad to maximize heat transfer. Each application should be evaluated at maximum expected constant current. For overloads, no heat sinking is required provided the SPDP10D375 is allowed some time to cool down. The SPDP10D375 has sufficient thermal mass that the temperature will rise only a few degrees under the worst-case overload. Repetitive overloads should be avoided. When the SPDP10D375 reports a trip condition, the controller driving the SPDP10D375 should allow no more than four repetitions and then allow thirty seconds to cool down before trying to turn on again. The SPDP10D375 will trip on overloads in the ALWAYS TRIP region and will never trip when in the NEVER TRIP region. It can be reset by bringing the CONTROL pin to a logic low. When the “CONTROL” pin is brought back to logic high, the SPDP10D375 will turn back on. If the overload is still present, it will trip again. Cycling the “5 Volt BIAS” power will also reset the SPDP10D375. If the “CONTROL” pin is at logic high when the “5 Volt BIAS” power is cycled, the SPDP10D375 will turn back on when the “5 Volt BIAS” power is re-applied. Status Table Table 5 shows the states of the “S1” and “S2” status outputs.

Normal Off – The SSPC is functioning normally and the channel is off. Both “S1” and “S2” status outputs go to a low level o Over Temperature – An unsafe operating temperature (116 C typical) is detected. a. During normal operation (2, 5), the channel will be turned off. When the temperature drops to o about 101 C, the “S2” status output goes back low and the output of the SPDP10D375 is turned back on b. During BS, the condition will only be reported. No Line Voltage - Both “S1” and “S2” status outputs go to a high level when the line voltage drops below 5 volts or when the load has not been discharged to 5V lower than the line voltage after turn off command. This status has higher priority than over temperature status. Normal On – The SSPC is functioning normally and the channel is on. 2 a. Tripped – The channel current surpassed the programmed I t/instant trip point of the SPDP10XD375. b. During normal operation the channel will turn off and “S1” will be high and “S2” will be low until reset. c. During BS, and “S1” will be high and “S2” will be low to indicate the condition has been detected. Battleshort On - The BS mode has priority over all status conditions that would turn off the channel. High Voltage Considerations The SPDP10D375 is designed for 375VDC systems. It contains an Output Leakage Sink to ensure that the output is at a safe voltage when it is off (whether it is turned off or is off due to loss of 5V BIAS Power). This circuitry absorbs the leakage current from the main switch and keeps the output voltage less than 1.5VDC over the temperature range. Figure 3 shows the Output Leakage Sink as a simple switch. However, the Output Leakage Sink is a transistor operating as a current source with a value of 80 mA. When the current into the output leakage sink is less than 80 mA, the transistor saturates and the output leakage sink looks like a resistor of about 60 Ohms. 80 mA can be used to determine how long it takes to discharge a particular load capacitance if the load is a pure capacitance. If the load is a combination of resistance and capacitance, it’s likely that the RC time constant will discharge the capacitance faster than the output leakage sink. Sufficient spacing should be allowed on the user’s PCB between the 375VDC line supply and the 375VDC power return and between the CONTROL and 5VDC Bias circuits and the 375VDC circuit to prevent arcing. Due to the small size of the SPDP10D375, the spacing between pins is small so conformal coating should be used to prevent arcing, especially if transient voltages above 375VDC are possible. Wire Size MIL-W-5088L has a chart that shows wire size as a function of wire temperature and current. This chart is o for a single copper wire in free air. For an ambient temperature of 70 C, the chart allows a 24-gauge wire to o o handle 10 Amps continuously at a wire temperature of 200 C – a wire temperature rise of 130 C. For a wire o o temperature limited to 150 C, the chart requires a 22-gauge wire and for a wire temperature of 105 C, the chart requires a 20-gauge wire. Amendment 1 of MIL-W-5088L has a table for copper wire in a bundle, group or harness with condition on the number of wires, percent of total harness capacity, etc. This table shows that an 18 gauge wire is o o o necessary for 200 C operation, 16-gauge for 150 C and 14-gauge for 105 C. © 2011 Sensitron Semiconductor 221 West Industry Court Deer Park, NY 11729-4681 Phone (631) 586 7600 Fax (631) 242 9798 www.sensitron.com [email protected] SENSITRON PROPRIETARY Page 10 SENSITRON ___ SEMICONDUCTOR SPDP10D270 SPDP10D375 PART NUMBER: SPDP10D270/SPDP10D375 DATASHEET 5223, Rev. MIL-W-5088L has various figures showing derating for harnesses as a function of the number of current carrying conductors for different altitudes. MIL-W-5088L only specifies wire for DC or RMS AC conditions, not for transient or overload conditions. MIL-W-5088L and its amendment should be consulted to determine minimum wire sizes for other currents and conditions. For transient or overload conditions, the transient or overload happens so quickly that heat is not transferred 2 from the wire to the surroundings. The heat caused by the I R heating of the wire causes the temperature to rise at a linear rate controlled by the heat capacity of the wire. The equation for this linear rise in 2 2 temperature, with respect to time, can be solved as: I t = constant. Every wire has an I t rating that’s 2 dependent on the temperature rise allowed and the diameter of the wire. If the I t rating of the SSPC or 2 circuit breaker is less than the I t rating of the wire, then the SSPC or circuit breaker can protect the wire. 2 2 The maximum I t rating for the SPD10D375 is 130 Amp -Seconds. Every wire size in the paragraphs above 2 has an I t rating that exceeds the SPDP10D375 I2t rating for the temperature rises stated. Therefore, to select a wire size, it’s simply a matter of determining the maximum temperature rise of the application and deciding whether or not the wire will be in a bundle and use the information above. Application Connections Due to the presence of the circuitry that keeps the output at safe voltage when the SPDP10D375 is off, it may only be configured as a high-side switch as shown in Figure 3. Rise Time & Fall Time The rise and fall times of the SPDP10D375 are pre-set at the factory for a nominal 2mS rise time and 500µS fall time with a LINE supply of 375VDC (see Table 1 for min/max limits). The rise and fall times will vary linearly with supply voltage. The “PWR RTN” pin is used to control the rise and fall times. If the “PWR RTN” pin is left open, the rise time will be around 400µS, and the fall time will be around 50µS (control to gate change delay will stay the same). Leaving the “PWR RTN” pin open can be useful when a faster rise or fall time is desirable; however, the Output Leakage Sink will not be functional with the “PWR RTN” pin open. And fault may be tripped by capacitive load. With the “PWR RTN” pin connected as in Figures 3, the SPDP10D375, when set for a 10 Amp rating, can turn on into a capacitive load of 80µF, typ. without tripping for any power supply voltage within the rating. Short circuit definition With the “PWR RTN” pin connected as in Figures 3, SPDP10D375 can survive at short circuit condition which has been defined by 0.1Ohm resistor in series with 1.35uH inductance cross the LOAD and LOAD_RTN. At 25 C, short circuit trip level has been defined as current larger than 70.7A (typical). And this short circuit trip level will decrease with temperature linearly at a rate of 0.33A/C (typical). So the unit will trip at lower current level when at higher temperature to protect itself, which means at high temperature, short circuit trip level may be lower than the set instant trip level. Wiring and Load Inductance Wiring inductance can cause voltage transients when the SPDP10D375 is switched off due to an overload. Generally, these transients are small but must be considered when long wires are used on either the “LINE” or “LOAD” pins or both. A 30 foot length of wire in free air will cause a transient voltage of about 10 Volts when the SPDP10D375 trips at an Instant Trip level of 70 Amps. At the rated load current of 10 Amps, the voltage transient will be less than 1 Volt. A transient suppressor is recommended at the “LINE” pin so that the total voltage between the “LINE” and “LOAD” pins is less than 500 Volts. The SPDP10D375V unit includes a reverse biased diode from the “LOAD” to “PWR RTN” pins to prevent damaging transients on the output due to inductive loads. © 2011 Sensitron Semiconductor 221 West Industry Court Deer Park, NY 11729-4681 Phone (631) 586 7600 Fax (631) 242 9798 www.sensitron.com [email protected] SENSITRON PROPRIETARY Page 11 SENSITRON ___ SEMICONDUCTOR SPDP10D270 SPDP10D375 PART NUMBER: SPDP10D270/SPDP10D375 DATASHEET 5223, Rev. Paralleling For example, putting two SPDP10D375s in parallel will not double the rating to 20 Amps. Due to differences in the Rds (on) of the Power Mosfets in the SSPCs, the current will not share equally. In addition, there are unit-to-unit differences in the trip curves so that two SPDP10D375s in parallel may possibly trip at 15 Amps. Also, both SPDP10D375s will not trip together; the SPDP10D375 carrying the higher current will trip first followed by the other SPDP10D375. Multiple units may be used in parallel as long as these complexities are appreciated. Board Layout The current-carrying power circuit should be kept well away from the control circuit and other low-level circuits in the system. It’s unlikely, but possible, that magnetic coupling could affect the control circuit when turning normal loads on and off. However, in the case of an overload, the magnetic coupling could be 10 times greater than with normal loads. Effects of such coupling could cause ‘chattering’ when turning on and off, oscillation, and the possibility of turning the SPDP10D375 back on after an overload. The SPDP10D375 is a Trip-Free device. Once tripped it will not turn back on until reset and commanded on again. Reset is accomplished by bringing the “CONTROL” pin low and then turning the SSPC back on by bringing the “CONTROL” pin high. Sufficient magnetic coupling between the current-carrying power circuit and the control circuit can negate the Trip-Free characteristic. MIL-STD-704F This standard covers the characteristics of the electrical systems in Military Aircraft. The SPDP10D375 meets all of the requirements of MIL-STD-704F including Normal, Emergency, Abnormal and Electric Starting conditions with the Ripple, Distortion Factor and Distortion Spectrum defined in the standard. In addition, the SPDP10D375 can withstand + 600 V spikes for 10µS. This capability is beyond that required by MIL-STD-704F.
