Fig. 2 is the truth table of the high-side driver module of BTS723 model.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
For above-mentioned purpose, the feature and advantage that make the utility model can be more obviously understandable, the utility model is done further detailed explanation below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the driving mechanism for switch structural drawing that is used for the former type controller of motor vehicle of the utility model.As shown in Figure 1, this driving mechanism for switch comprises:
High-side driver module 101, GIO 102, anti-power supply reversal connection resistance 103 and fly-wheel diode 104; Said high-side driver module comprises control input end IN, voltage status feedback end ST, control voltage output end OUT1 and OUT2, supply voltage input end VBB and ground GND;
Said control input end IN links to each other with the output terminal of said GIO 102; Said voltage status feedback end ST links to each other with the input end of said GIO 102; Link to each other with an end of said fly-wheel diode 104 after said control voltage output end OUT1 and the OUT2 parallel connection; The other end of said fly-wheel diode 104 with systematically link to each other; Said supply voltage input end VBB links to each other with system voltage UB R, and described ground GND links to each other with an end of anti-power supply reversal connection resistance 103, the other end of said anti-power supply reversal connection resistance 103 with systematically link to each other.
Driving mechanism for switch in the utility model can be used with microprocessor unit (MCU).Concrete, GIO 102 can be arranged on the GIO on the MCU.GIO 102 receives the control of MCU, and then to the input end IN of high-side driver module 101 output height different voltages with different.When to the input end IN of high-side driver module 101 output HIGH voltage, high-side driver module 101 can be controlled inner FET conducting.When to the input end IN of high-side driver module 101 output LOW voltage, high-side driver module 101 can be controlled inner FET and be in closed condition.By the way, can realize switch control functions.(PulseWidth Modulation, when PWM) mode drove inductive load, fly-wheel diode 104 played a role with pulse-length modulation when needs.When PWM was high level, drive current flow to load by power supply through the high-side driver module, and when PWM was low level, electric current then continued to flow between load and fly-wheel diode, and slowly reduces.
