infineon公司的iMOTION™ IMM101T/IMM102T系列是全集成交钥匙的高压马达驱动模块,设计用于高性能高效率PMSM/BLDC马达驱动应用如风扇,泵和压缩机.器件集成了Infineon公司的先进的运动控制引擎(MCE),栅极驱动器和六个功率MOSFET.IMM101T/IMM102T系列属于IMM100系列iMOTION™智能功率模块(IPM),它包括两个系列:A系列和T系列.A系列(IMM100A-xxx)包括全编程的ARM® Cortex®-M0控制器,而T系列(IMM10xT-xxx)包括专利的运动控制引擎(MCE).IMM100系列集成了500VFredFET或 650V CoolMOS,以及业界基准的三相高压鲁棒栅极驱动器和引导功能.它的额定输出功率从25W到80W,最高DC电压500V/600V,栅极驱动器的额定电压600V.本文介绍了IMM101T/IMM102T系列主要特性,单分流配置和支腿分流配置应用框图,栅极驱动器功能框图以及评估板EVAL-IMM101T主要特性和指标,框图,电路图,材料清单,PCB设计图和多个应用电路图.

IMM101T/IMM102T series is a family of fully-integrated, turnkey high-voltage Motor Drive Module designed for high-performance, high-efficiency PMSM/BLDC motor drive applications such as fans, pumps and compressors. It integrates Infineon’s Advanced Motion Control Engine (MCE), gate driver and six power MOSFETs in a single 12x12mm package.

IMM101T/IMM102T devices belong to IMM100 series of iMOTION™ Smart IPMs. IMM100 series is a family of fully-integrated, programmable or configurable (“turnkey”) high-voltage Motor Drive Modules designed for high-performance, high-efficiency PMSM (BLDC) motor drive applications such as fans, pumps and compressors. It integrates a controller, a gate driver and six power MOSFETs. IMM100 series is available in two variants: “A”-variant and “T”-variant. “A”-variant (IMM100A-xxx) includes a fully programmable ARM® Cortex®-M0 controller, while “T”- variant (IMM10xT-xxx) features the Infineon’s patented Motion Control Engine (MCE).

Both variants offer different control configuration options for PMSM motor-drive system in a compact 12x12mm surface-mount package which minimizes external components count and PCB area. This thermally enhanced package provides excellent thermal performance working with or without heatsink. The package features a 1.3mm creepage distance between the high-voltage pads beneath the package to ease the surface mounting with standard SMT process and increase the robustness of the system.

IMM100 series integrates either 500V FredFET or 650V CoolMOS and the industry benchmark 3-phase high-voltage, rugged gate driver with integrated bootstrap functionality. Depending on the power MOSFETs employed in the package, IMM100 series covers applications with a rated output power from 25W to 80W with 500V/600V maximum DC voltage. In the 600V versions, the Power MOS technology is rated 650V, while the gate driver is rated 600V, which determines the maximum allowable DC voltage of the system.

IMM101T/IMM102T系列主要特性:

 Motion control engine (MCE) as ready-to-use controller solution for variable speed drives
 Field oriented control (FOC) for permanent magnet synchronous motor (PMSM)  Space vector PWM with sinusoidal commutation and integrated protection features
 Current sensing via single or leg shunt through direct interface
 Sensorless operation
 Integrated analog comparators for over-current protection
 Built-in temperature sensor
 3.3V or 5.0V supply voltage options for controller
 15V supply voltage for gate driver
 3 different power MOSFET options: 6Ω/500V, 1.4Ω/650V and 0.95Ω/650V
 Integrated bootstrap FET
 Support for hall sensors
 Boost PFC control (IMM102T only)
 Flexible host interface options for speed commands: UART, PWM or analog signal
 Support for IEC 60335 (‘Class B’)
 Isolation 1500VRMS 1min
 Very compact 12x12mm PQFN package

IMM101T/IMM102T系列应用:

 Fans
 Pumps
 Compressors

评估板EVAL-IMM101T

This application note provides an overview of the evaluation board EVAL-IMM101T including its main features, key technical data, pin assignments and mechanical dimensions.

EVAL-IMM101T is a full-featured Starter Kit including an IMM101T Smart IPM which provides a fully-integrated, turnkey high-voltage motor drive solution designed for high-performance, high-efficiency PMSM/BLDC motor drive applications such as fans, pumps and compressors. EVAL-IMM101T also comprises other necessary circuitry required for “out-of-the-box” evaluation of IMM101T Smart IPMs, such as rectifier and EMI filter stage, as well as isolated debugger section with USB connection to the PC.

The Starter Kit EVAL-IMM101T was developed to support customers during their first steps designing applications with IMM101T Smart IPM.

The EVAL-IMM101T Starter Kit is designed to give an easy-to-use motor drive solution based on the Infineon ’s IMM101T Smart IPM.The board is equipped with all assembly groups for sensorless field oriented control (FOC). It contains a single-phase AC-connector, EMI filter, rectifier and 3-phase output for connecting the motor. The power stage also contains source shunt for current sensing and a voltage divider for DC-link voltage measurement.

The features of this board are described in the design feature chapter of this document, whereas the remaining paragraphs provide information which helps users to copy, modify and qualify the design for production according to their own specific requirements.

Environmental conditions were considered in the design of the EVAL-IMM101T. The design was tested as described in this document but not qualified regarding safety requirements or manufacturing and operation over the whole operating temperature range or lifetime. The boards provided by Infineon are only subject to functional testing.

Evaluation boards are not subject to the same procedures as regular products regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD). Evaluation boards are intended to be used under laboratory conditions and only by trained specialists.

The combination of the MCE2.0 iMOTION™ motion control engine integrated into IMM101T devices, toghether with the gate driver and six MOSFETs offers a complete motor drive system in a compact 12 x 12mm2 surface mount package, minimizing external components count and PCB area.
