5 / 28 page AN-9080 APPLICATION NOTE © 2013 Fairchild Semiconductor Corporation www.fairchildsemi.com Rev. 1.0.1 • 4/16/14 5 To prevent malfunctions caused by noise and ripple in supply voltage, a good quality filter capacitor with low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL) should be mounted very close to these pins. Low-Side Bias Voltage Pin / High-Side Bias Voltage Pin Pin: VCC(U), VCC(V), VCC(W) These are control supply pins for the built-in ICs. These three pins should be connected externally. To prevent malfunctions caused by noise and ripple in the supply voltage, a good quality filter capacitor with low ESR and ESL should be mounted very close between these pins and the COM pins. Low-Side Common Supply Ground Pin Pin: COM The common (COM) pin connects to the control ground for the internal ICs. Important! To prevent switching noises caused by parasitic inductance from interfering with operations of the module, the main power current should not flow through this pin. Signal Input Pins Pins: IN(UL), IN(VL), IN(WL), IN(UH), IN(VH), IN(WH) These pins control the operation of the MOSFETs. These pins are activated by voltage input signals. The terminals are internally connected to the Schmitt trigger circuit. The signal logic of these pins is active HIGH; the MOSFET turns ON when sufficient logic voltage is applied to the associated input pin. The wiring of each input needs to be short to protect the module against noise influences. An RC filter can be used to mitigate signal oscillations or any noise that traces of input signals may pick up. Analog Temperature Sensing Output Pin Pin: Vts This indicates the temperature of the V-phase HVIC with analog voltage. HVIC itself creates some power loss, but mainly heat generated from the MOSFETs increases the temperature of the HVIC. Vts versus temperature characteristics is illustrated in Figure 16. Positive DC-Link Pin Pin: P This is a DC-link positive power supply pin of the inverter. This pin is internally connected to the drains of the high-side MOSFETs. To suppress the surge voltage caused by the DC-link wiring or PCB pattern inductance, connect a smoothing filter capacitor close to this pin and the negative DC- link. Figure 35 shows more details. Typically metal film capacitors are recommended. Negative DC-Link Pins Pins: NU, NV, NW These are DC-link negative power supply pins (power ground) of the inverter. These pins are connected to the source of low-side MOSFET in each phase. Inverter Power Output Pin Pins: U, V, W Inverter output pins to be connected to the inverter load, such as an electrical motor. 3.3. Package Structure Figure 4 shows the internal package structure, including the lead frame and bonding wires. This design has been revised several times to further improve the manufacturability and the reliability for customers. Figure 4. Package Structure |
