IRMCS3041
2.3 IRMCF341
2.3.1 Power
IRMCF341 requires 3.3V and 1.8V. VDD1 is 3.3V used for I/O and VDD2 is 1.8V for digital logic. AVDD is 1.8V
for analog and PLLVDD is1.8V for PLL. Only one source of 1.8V is shared in IRMCS3041 system. Typical current
value for 1.8V is less than 100mA.
2.3.2 Crystal
A 4 MHz crystal is used to generate the system clock. Actual system frequency is adjustable by changing Phase
Locked Loop configuration through Special Function Registers. For more information regarding the clock, please refer
to the IRMCx300 Reference Manual.
2.3.3 Reset Circuit
IRMCF341 doesn’t require external RC circuit for reset. The reset switch can be used to initialize the JTAG debugger.
For more information regarding reset, please refer to the IRMCx300 Reference Manual.
2.3.4 EEPROM
Boot load takes place at power-up to load 8051 code and MCE code from an external EEPROM to internal RAM of
IRMCF341. EEPROM can be written by MCEDesigner.
2.3.5 Digital I/O
Only some of the digital I/O’s are used in IRMCS3041. For example, ‘P1.5’ and ‘P1.6’ are used to drive the LED to
indicate the status of the system. The remainders are connected to headers (J3, J7) for the user’s convenience.
2.3.6 Analog Input
Analog channels are connected to header J5 for ease of use.
2.3.7 Single Shunt Current Feedback
IRMCF341 contains an Operational Amplifier for single shunt current reconstruction circuit. Resistors and capacitors
for amplifier circuit are placed very close to the pins. Note that there is a separate trace from shunt resistor instead of
sharing a plane with negative DC bus ground to get better current feedback.
2.4 IRAM
IRAMS10UP60B in mounted on a heat sink under the board. Voltage across 33.3 m ? shunt is fed to ‘Itrip’ pin of
IR21363 high voltage gate driver IC through low pass filter with 2 μ sec time constant to initiate the over-current
shutdown (Gatekill). For more information regarding IRAM, please refer to IRAM datasheet.
2.5 Power Supply
Switch mode power supply operates at about 80 kHz and generates 15V(VCC), 3.3V and isolated 5V. 1.8V is
generated from 3.3V by a linear regulator IRU1208.
2.6 EMI Filter
Passive EMI filter on the board consists of two 0.1 μ F X-caps and two 2.2 nF Y-caps and a 1 mH common mode
inductor. Y-caps are connected to the heat sink through a metal bar and to J1 pin 1, which is assigned as earth ground.
2.7 DC Bus Capacitor
A 470 μ F, 400 V, 85 ° C electrolytic capacitor is used to supply instantaneous power to IRAM. IRMCS3041 doesn’t
have a dynamic braking unit. In case of field weakening operation, it is recommended to use an external regenerative
unit or a braking unit for safety. Pin 4(GND) and Pin 5(DCP) of J1 can be used for connecting an external unit.
