41 Hardware Description. POWER SUPPLY CIRCUIT The dspic DSC Signal Board has two power supply circuits: Power Supply and Power Supply (see Figure -) with identical topology. Power Supply has a fixed +5V output, while the output of Power Supply can be switched between +.V/+5V, depending on the dspic DSC or microcontroller used. FIGURE -: POWER SUPPLY CIRCUIT ARCHITECTURE Power Supply DCLOCAL +5V Buck Converter LDO (MCP60) (MCP86) EN TP J4 Feedback Feedback Power Supply TP DCLOCAL Buck Converter (MCP60) LDO (MCP86) Feedback Feedback J8 J9 Input for the power supply circuits is provided either through power connector jack J7, or through pins of connectors J and J7 with a DC+ signal. The power supply circuit has these key features: High efficiency Low ripple output Snubber circuit or ferrite bead provided to minimize switching noise 04 Microchip Technology Inc. DS50006A-page 4

42 dspic DSC Signal Board The power supply provides power to these components: A dspic DSC or microcontroller device, an isolator (ADUM0CRZ) and the reference voltage circuit for op amps receives +.V/+5V power from Power Supply J and J7 connector pins with a digital voltage () signal receive power from Power Supply (see Note ) J and J7 connector pins with a fixed +5V signal receive power from Power Supply (see Note ) Note : For the power connector jack J7, a 4V power supply (AC000) is recommended. : When the dspic DSC Signal Board is used with Microchip s Motor Control 0-4V Driver Board (Dual/Single), the connection of a power supply to the dspic DSC Signal Board is optional. The output of a fixed +5V power supply circuit can be disabled using jumper J4. When Pins - on the connector J4 are connected, Power Supply is enabled with a fixed +5V DC output voltage. However, when Pins - are connected, Power Supply is disabled (see Note )... Power Supply Output Selection The Power Supply is interfaced with the PIM through connectors J8 and J9 (see Figure -). When connectors J8 and J9 are short-circuited on the PIM, it generates +5V DC. When connectors J8 and J9 are open-circuited on the PIM, +.V DC is generated.

43 Hardware Description.4 VOLTAGE REFERENCE CIRCUIT The reference voltage is generated on the dspic DSC Signal Board. It is half the output of Power Supply (+.65V or +.5V) depending upon. The reference circuit is built around an MCP60 op amp (see Figure -4) and connects to several PIM header pins (see Table -). The reference voltage is also connected to connector J (see Table -). Figure -4 shows the circuit used to obtain the voltage reference signal which is half the magnitude of the. The resistors R5 and R6 form the voltage divider circuit and generate a voltage equal to half of the analog voltage (). Op Amp U MCP60 is used as the buffer. The resistors R8, R8 and C0 form a compensation circuit to drive capacitive loads, where C0 acts as a high-frequency feedback path and R8 is used as a feedback path for low-frequency signals.

It can be supplied by the circuit on the dspic DSC Signal Board (see Figure -4) or it can also be supplied externally from the J connector pins. The reference voltage selection can be made by populating one of the two resistors: RINT or REXT. Table - provides the list of resistors used to connect the reference signal.

45 Hardware Description.6 PIM HEADER SIGNALS.6. Signal Nomenclature The dspic DSC signals use the following naming convention (except for auxiliary power supply pins): PIM:xx_PWR:yy_EXP:zz[_FLT] where: PIM:xx indicates that the signal originates at PIM Pin Number xx PWR:yy indicates that the signal is connected to Pin yy of the power board interface connector (J) EXP:zz indicates that the signal is connected to Pin zz of the expansion board connector (J7) [_FLT]: if present, indicates that the signal between the connector J and the PIM is filtered (see Figure -7 to Figure -0 for different connection topologies)..6. Analog Input Signal Conditioning The PIM pins are connected to the power board interface connector J and the expansion board connector J7 by the following four possible topologies: Topology : In this topology, there is a first order low-pass filter and voltage surge protection diodes between the PIM header and the connectors. Figure -7 shows the connection between the PIM header and the connectors J, J7, J4 and J5. Topology : In this topology, there is a first order low-pass filter and voltage surge protection diodes between the PIM header and the connectors. Figure -8 shows the connection between the PIM header and the connector J. These signals are not connected to connectors J7, J4 and J5. Topology : In this topology, there is no connection for a first order filter. Figure -9 shows the direct connection between the PIM header and the connectors J, J7, J4 and J5. Topology 4: In this topology, there is no connection for a first order filter. Figure -0 shows the direct connection between the PIM header and the connector J. These signals are not connected to connectors J7, J4 and J5. 04 Microchip Technology Inc. DS50006A-page 45

48 dspic DSC Signal Board.7 SUPPLY VOLTAGE AND GROUND CONNECTION The dspic DSC Signal Board has three separate grounds: Digital Ground (), Analog Ground () and Power Ground (PGND). All three grounds can be connected by populating the resistors R74 and R75 (see Figure -). and are connected through R9 (0 ) by default. The Analog Voltage () is derived from through R0 (0 ), see Figure -. Note: PGND is expected to be connected to and on application boards. To avoid ground loops, PGND is not connected to and on the dspic DSC Signal Board.
