DIPIPM Application Design Guide
This technical reference document provides detailed information about mitsubishi product specifications, characteristics, and performance parameters. Use this information to support your design and analysis activities.
Electrical characteristics are specified over the operating temperature range unless otherwise noted. Parameters are guaranteed by design, testing, or statistical analysis. Typical values is the most likely parametric norm at 25°C.
Thermal characteristics require careful attention during system design. The junction-to-ambient thermal resistance depends on the mounting configuration, PCB copper area, and airflow conditions. Use thermal simulation tools to predict operating temperatures under actual conditions.
Reliability data is based on accelerated life testing and field failure analysis. Mean time between failures (MTBF) calculations follow industry-standard methodologies. Contact BeiLuo for detailed reliability reports and qualification data.

Frequently Asked Questions
1. What are the main advantages of using DIPIPM over discrete IGBTs?
DIPIPM advantages: (1) Integration - 70% fewer external components. (2) Design time - Faster time-to-market. (3) Cost - Lower total system cost. (4) Reliability - Factory-tested, proven in 100M+ units. (5) Protection - Built-in UVLO, OT, FO. (6) Size - Compact DIP package. (7) Support - Extensive application support. DIPIPM is the proven choice for appliance motor control.
2. How do I calculate the bootstrap capacitor value?
Bootstrap capacitor calculation: (1) Formula: Cboot > 2×(2Qg + Iq/fsw + Qls)/Vripple. (2) Qg: Total gate charge of high-side IGBT. (3) Iq: Quiescent current of HVIC. (4) fsw: Switching frequency. (5) Qls: Charge required per switching cycle. (6) Vripple: Allowed voltage ripple (typically 1V). (7) Typical value: 10-47μF, 25V rating. Use low-ESR ceramic or electrolytic capacitor.
3. What protection functions are built into DIPIPM?
DIPIPM protection features: (1) UVLO - Undervoltage lockout disables output below 10.5V. (2) OT - Overtemperature shutdown at 145°C. (3) FO - Fault output indicates protection activation. (4) SC - Short-circuit protection with soft turn-off. (5) Interlock - Prevents shoot-through. (6) Input filter - 1μs noise filter. These protections operate automatically without external circuitry.
4. How do I interface DIPIPM with my microcontroller?
MCU interface: (1) Control inputs - 6 pins (HIN/LIN per phase). (2) Logic level - 3.3V or 5V compatible. (3) Input current - 1mA typical. (4) Pull-down - Built-in, No external is needed. (5) Dead time - Add 2-5μs in software. (6) FO output - Open-drain, use 10kΩ pull-up. (7) VFO - Connect to MCU VCC. Interface requires only 6 GPIO pins and one pull-up resistor.
5. What is the maximum motor power for DIPIPM applications?
DIPIPM power capability: (1) Super Mini - Up to 1.5kW with 20A modules. (2) Large DIPIPM+ - Up to 2.2kW with 30A modules. (3) Voltage - 600V for 220V AC systems. (4) Current - Continuous rating at 25°C ambient. (5) Overload - 150% for 60 seconds typical. (6) Applications - Air conditioners, refrigerators, washing machines. (7) Limitations - Not suitable for industrial drives above 2.2kW.
6. How do I troubleshoot DIPIPM fault conditions?
DIPIPM troubleshooting: (1) Check FO pin - Low indicates fault condition. (2) UVLO fault - Check 15V supply voltage and decoupling. (3) OT fault - Verify heatsinking and airflow. (4) SC fault - Check for motor short or wiring error. (5) Input signals - Verify dead time and signal integrity. (6) Bootstrap - Check capacitor value and charging. (7) Reset - Cycle power or toggle reset pin. Most faults can be diagnosed by monitoring FO and supply voltages.
