3 CIPOS Control Integrated POwer System Dual InLine Intelligent Power Module 3Φ bridge 6V / 4A Features Fully isolated Dual InLine molded module Reverse conducting IGBTs with monolithic body diode Rugged SOI gate driver technology with stability against transient and negative voltage Allowable negative VS potential up to V for signal transmission at VBS=5V Integrated bootstrap functionality Over current shutdown Temperature monitor Undervoltage lockout at all channels Low side common emitter Crossconduction prevention All of 6 switches turn off during protection Leadfree terminal plating; RoHS compliant Target Applications Dish washers Refrigerators Fans Low power motor drives Description The CIPOS module family offers the chance for integrating various power and control components to increase reliability, optimize PCB size and system costs. It is designed to control three phase AC motors and permanent magnet motors in variable speed drives for applications like a refrigerator and a dish washer. The package concept is specially adapted to power applications, which need good thermal conduction and electrical isolation, but also EMIsave control and overload protection. The reverse conducting IGBTs are combined with an optimized SOI gate driver for excellent electrical performance.

The Schmitttrigger input thresholds of them are such to guarantee LSTTL and CMOS compatibility down to 3.3V controller outputs. Pulldown resistor of about 5k is internally provided to prebias inputs during supply startup and a zener clamp is provided for pin protection purposes. Input Schmitttrigger and noise filter provide beneficial noise rejection to short input pulses. The noise filter suppresses control pulses which are below the filter time t FILIN. The filter acts according to Figure 4.

6 It is not recommended for proper work to provide input pulsewidth lower than µs. The integrated gate drive provides additionally a shoot through prevention capability which avoids the simultaneous onstate of two gate drivers of the same leg (i.e. HO and LO, HO2 and LO2, HO3 and LO3). When two inputs of a same leg are activated, only former activated one is activated so that the leg is kept steadily in a safe state. A minimum deadtime insertion of typically 38ns is also provided by driver IC, in order to reduce crossconduction of the external power switches. VFO (Faultoutput and NTC, Pin 4) The VFO pin indicates a module failure in case of under voltage at pin VDD or in case of triggered over current detection at ITRIP. A pullup resistor is externally required. VDD VFO VSS Figure 5 Thermistor R ON,FLT CIPOS TM From ITRIP Latch From UV detection Internal circuit at pin VFO The same pin provides direct access to the NTC, which is referenced to VSS. An external pullup resistor connected to +5V ensures that the resulting voltage can be directly connected to the microcontroller. ITRIP (Over current detection function, Pin 5) CIPOS provides an over current detection function by connecting the ITRIP input with the IGBT collector current feedback. The ITRIP comparator threshold (typ..47v) is referenced to VSS ground. An input noise filter (typ.: t ITRIPMIN = 53ns) prevents the driver to detect false overcurrent events. Over current detection generates a shutdown of all outputs of the gate driver after the shutdown propagation delay of typically ns. The faultclear time is set to minimum 4µs. VDD, VSS (Low side control supply and reference, Pin 3, 6) VDD is the control supply and it provides power both to input logic and to output power stage. Input logic is referenced to VSS ground. The undervoltage circuit enables the device to operate at power on when a supply voltage of at least a typical voltage of V DDUV+ = 2.V is present. The IC shuts down all the gate drivers power outputs, when the VDD supply voltage is below V DDUV =.4V. This prevents the external power switches from critically low gate voltage levels during onstate and therefore from excessive power dissipation. VB(U, V, W) and VS(U, V, W) (High side supplies, Pin 6) VB to VS is the high side supply voltage. The high side circuit can float with respect to VSS following the external high side power device emitter voltage. Due to the low power consumption, the floating driver stage is supplied by integrated bootstrap circuit. The undervoltage detection operates with a rising supply threshold of typical V BSUV+ = 2.V and a falling threshold of V BSUV =.4V. VS(U, V, W) provide a high robustness against negative voltage in respect of VSS of 5V transiently. This ensures very stable designs even under rough conditions. N (Low side common emitter, Pin 7 9) The low side common emitter is available for current measurement. It is recommended to keep the connection to pin VSS as short as possible in order to avoid unnecessary inductive voltage drops. W, V, U (High side emitter and low side collector, Pin 2 22) These pins are motor U, V, W input pins. P (Positive bus input voltage, Pin 23) The high side IGBTs are connected to the bus voltage. It is noted that the bus voltage does not exceed 45V. Datasheet 6 of 7 V
