  • a device which passively outputs a high voltage but can be pulled to OV is referred to as a "low-side pull driver.”
  • a device which can actively force a high voltage and a low voltage, but by default is passively electrically disconnected is referred to as a "push-pull driver.”

  • the push-pull driver also has a first and a second switch.
  • the first switch is controllably coupled to the push driver, and the second switch is controllably coupled to the pull driver.

  • Figure 2 illustrates an example low-side pull driver.
  • Figure 3 is a schematic view of an example power train controller.
  • FIG. 1 illustrates a schematic diagram of an integrated circuit (IC) 100 for a push-pull driver.
  • the IC 100 has a push controller 10 and a pull controller 20 contained within a general controller 18.
  • the push controller 10 is connected to a switch 12, and the pull controller 20 is connected to a switch 22.
  • the first switch 12 interrupts a power line 38 connecting a positive voltage input 34 to the output 30, and the second switch 22 connects the output 30 to a ground 36.
  • the general controller 18 which can control the timing of each of the push controller 10 and the pull controller 20.
  • the driver output 30 is connected between the switches 12, 22.
  • a single controller input line 32 sends an input to both the push controller 10 and the pull controller 20 and is capable of setting the operational mode of the push-pull driver. Alternately, two individual controller input lines could be used to the same effect.
  • the IC 100 also has diagnostic circuitry 14, 24 connected to each of the controllers 10, 20 which can analyze the outputs of the controllers 10, 20 as well as determine the health and functionality of the overall IC 100 in its current operational mode.
  • the push controller 10 and the pull controller 20 alternate which switch 12, 22 is turned on.
  • the voltage source 34 has an input voltage of approximately 5V.
  • this input is achieved through the use of a DC voltage source, such as a battery.
  • the push controller 10 closes the switch 12, and the pull controller 20 opens the switch 22, resulting in creation of a current flowpath from the voltage source 34 input to the push-pull output 30.
  • the pull controller 20 closes the switch 22, and the push controller 10 opens the switch 12 resulting in a direct flow path from the push-pull output 30 to ground 36, thereby achieving a OV output.
  • both the switches 12, 22 are open and no current flow path is provided to the output 30
  • Each of the controllers 10, 20 of Figure 1 are additionally configured to operate the IC 100 in a "low-side pull" mode when they receive a preconfigurable input on the controller input line 32.
  • a schematic diagram of the IC 100 of Figure 1 operating in low-side pull mode is illustrated in Figure 2 (IC 200) with non-relevant electrical components removed.
  • IC 200 In low-side pull mode the majority of the high side electronics illustrated in Figure 1 are disconnected resulting in the electrical schematic of IC 200 in Figure 2.
  • IC 200 maintains identical physical components to IC 100, due to the affect of the disconnected electronics in low-side pull mode, the circuit components have been renumbered for Figure 2.
  • the control input 132 is connected to each of the high side controller 110 and the low side controller 120, and places the IC 200 into the low-side pull mode when a pre-configured input is received.
  • the push controller 110 switches the high side switch 12 (illustrated in Figure 1) open and the high side switch 12 remains in the open state for the duration of the low- side pull mode operations. Consequently, the switch 12 has a negligible electrical effect, and is not illustrated in Figure 2.
  • the pull controller 120 is connected to a second switch 122, and diagnostic circuitry 124 is connected in the same manner as when the IC 200 is operating in push-pull mode (illustrated in Figure 1).
  • the pull controller 120 While operating in a low-side pull mode, the pull controller 120 closes the switch 122 when in the default state, thereby creating a constant, direct flow path between the output 130 and the ground 136. When a low voltage (OV) output is required, the pull controller 120 closes the switch 122, thereby pulling the output 130 to ground. This allows for the output 130 to be passively high, while at the same time able to be forced to OV (ground).
  • OV low voltage
  • the modifiable configuration of the IC 100, 200 of Figures 1 and 2 allows a single IC to be manufactured, and utilized in multiple different applications.
  • the push controller 10 and the pull controller 20 can also have a memory unit which is capable of retaining the operational mode of the push-pull controller even after a control input 32, 132 has been disconnected. This allows the IC to be configured and then the control signal removed, thereby allowing for use in a broader range of applications.
  • the push-pull / low-side pull mode can be changed or reset by either sending a reset signal to the control input 132, 32 or by removing power from the IC 100, 200. In the case that power is removed form the IC 100, 200, a "default" mode will be entered up on repowering the IC 100, 200.
  • the default mode can be determined during manufacturing, and programmed into the controllers 10, 20.
  • the IC 100/200 of Figures 1 and 2 can accept a control input32/132, and based on that control input 32/132 determine what mode to operate in. Once the operational mode has been determined, the push controller 10/110 and the pull controller 20/120 engage in the actions described above to force the output 30/130 to the appropriate values. The controllers 10/110, 20/120 can then control the timing of the voltage on the output 30/130 by opening and closing the appropriate switches 12, 22/122 whenever the output needs to be changed. If an internal memory is used in the controllers 10/110, 20/120 a continued input 32/132 is not necessary, and instead the controllers 10/110, 20/120 will stay in their current operational mode until a new input 32/132 replaces the stored input value.
  • FIG. 3 A typical use of the modifiable IC 100/200 is illustrated in Figure 3.
  • the IC 100/200 output 130/30 is connected to a power train controller 210.
  • the output 130/30 can then output a control signal which has either a high value or a low value, when the IC 100/200 is in a low-side pull mode, or a high value, a low value, or no value, when the IC 100/200 is in a push-pull mode.
  • the IC 100/200 could be used in a diesel power train control apparatus 300 to control a relay by being operated in a low-side pull mode.
  • the same IC 100/200 could also be used in a gasoline engine power- train controller apparatus 300 to control spark timing by being operated in a push-pull mode.
  • the IC 100/200 mode is controlled as described above with regards to Figures 1 and 2 by a control input 232.
  • switches are shown as being FET' s (field effect transistors).
  • FET' s field effect transistors
  • alternate configurations could use other types of electrical switches to perform the same function.
  • a network of multiple electrical switches could provide the same function.
