意法半导体的SLLIMM’小型低损耗智能模制模块系列IPM采用了优化的硅芯片,集成于3种主逆变器模块内:

  • 功率级
    –短路保护IGBT
    –续流二极管
  • 驱动网络
    –高压栅极驱动器
    –分立栅极电阻
    –集成式自举二极管
  • 保护及可选特性
    –智能关断功能
    –用于过流和短路故障保护的比较器
    –用于温度控制的NTC传感器
    –用于高级电流感应的运算放大器
    –死区时间、互锁功能和欠压闭锁

它们采用基于DBC的SDIP封装(它提供了超低热阻、高质量水平和高成本效益)或者全模制3.5cm² SLLIMM-nano封装(NDIP,是小型内置式电机应用的理想之选,有效截面内的功率高达100W)。

MOSFET-based SLLIMM-nano modules

ST has extended its offering of intelligent power modules with the introduction of the MOSFET-based SLLIMM-nano devices (1 A and 2 A current rating at 25 °C, with 500 V breakdown voltage). The low MOSFET on-resistance (3.6 Ω and 1.7 Ω, in 2 A and 1 A variants, respectively) combined with low switching losses ensure high overall energy efficiency and reduced cost.
They target applications up to 100 W, such as compressors, pumps, fans and other low power motor drives working up to 20 kHz in hard-switching circuitries.
The new devices are available in zig-zag lead and in line-lead package options giving designers extra flexibility to simplify the board layout and minimize controller size in mechatronic assemblies and other space-constrained applications.
