1200 W motor control power board based on STIB1060DM2T-L SLLIMM™ 2nd
Introduction
The
STEVAL-IPMM10B
is a compact motor drive power board equipped with SLLIMM™ (small low-loss intelligent molded
module) 2nd series based on n-channel power MOSFET MDmesh™ DM2 fast-recovery diode (STIB1060DM2T-L). It provides
an affordable and easy-to-use solution for driving high power motors for a wide range of applications such as power white
goods, air conditioning, compressors, power fans, high-end power tools and 3-phase inverters for motor drives in general. The
IPM itself consists of MOSFETs and a wide range of features like undervoltage lockout, smart shutdown, embedded
temperature sensor and NTC, and overcurrent protection.
The main characteristics of this evaluation board are small size, minimal BOM and high efficiency. It consists of an interface
circuit (BUS and VCC connectors), bootstrap capacitors, snubber capacitor, hardware short-circuit protection, fault event and
temperature monitoring. In order to increase the flexibility, it is designed to work in single- or three-shunt configuration and with
double current sensing options such as using three dedicated onboard op-amps, or op-amps embedded in the MCU. The Hall/
Encoder part completes the circuit.
Thanks to these advanced characteristics, the system has been specifically designed to achieve fast and accurate current
feedback conditioning, satisfying the typical requirements for field-oriented control (FOC).
The
STEVAL-IPMM10B
is compatible with ST's STM32-based control board, enabling designers to build a complete platform for
motor control.

    An internal charge pump provides the DMOS driving voltage. The value of the CBOOT capacitor should be calculated according to the application condition. This curve is taken from application note AN4768 (available on www.st.com); calculations are based on the STGIB15CH60TS-L device, which represents the worst case scenario for this kind of calculation.
  • Page 11: Sd Pin

    UM2702 Overcurrent protection 4.3.1 SD Pin The SD is an input/output pin (open drain type if used as output). Taking into account the voltage reference on SD (3.3 V), a pull up resistor of 10 kΩ (R28) is used to guarantee the right bias and consequently to keep the current on the open drain DMOS (Iod) lower than 3 mA.

    UM2702 Overcurrent protection Figure 10. SD failure due to overcurrent Figure 11. SD failure due to undervoltage (UVLO below 70 μs) shows the shutdown event as the result of an undervoltage condition on the V supply. If V drops below the undervoltage threshold, the shutdown can stop the application.

    Current sensing amplifying network Current sensing amplifying network The STEVAL-IPMM10B motor control demonstration board can be configured to run in three-shunt or single-shunt configurations for field oriented control (FOC). The current can be sensed thanks to the shunt resistor and amplified by using the on board operational amplifiers or by the MCU (if equipped with op-amp).

    UM2702 Temperature monitoring Temperature monitoring The SLLIMM 2nd series family integrates a temperature sensor (VTSO) on the low side gate driver and an NTC thermistor placed close to the power stage. They can be selected via SW3. The board is designed to use both of them to monitor the internal IPM temperature through the MCU. Thermal sensor (VTSO) A voltage proportional to the temperature is available on the TSO pin (17) and easily measurable on the TP20 test pin.

    UM2702 General safety instructions General safety instructions Danger: The evaluation board works with high voltage which could be deadly for the users. Furthermore all circuits on the board are not isolated from the line input. Due to the high power density, the components on the board as well as the heat sink can be heated to a very high temperature, which can cause a burning risk when touched directly.
