Application note
SLLIMM™-nano
small low-loss intelligent molded module
By Carmelo Parisi and Giovanni Tomasello
Introduction
In recent years the variable speed motor control market has required high performance
solutions able to satisfy the increasing energy saving requirements, compactness, reliability,
and system costs in home appliances, such as dish washers, refrigerator compressors, air
conditioning fans, draining and recirculation pumps, and in low power industrial applications,
such as small fans, pumps and tools, etc. To meet these market needs, STMicroelectronics
has developed a new family of very compact, high efficiency, dual-in-line intelligent power
modules, with optional extra features, called small low-loss intelligent molded module nano
(SLLIMM™-nano).
The SLLIMM-nano product family combines optimized silicon chips, integrated in three main
inverter blocks:
● power stage
– six very fast IGBTs
– six freewheeling diodes
● driving network
– three high voltage gate drivers
– three gate resistors
– three bootstrap diodes
● protection and optional features
– op amp for advanced current sensing
– comparator for fault protection against overcurrent and short-circuit
– smart shutdown function
– dead time, interlocking function and undervoltage lockout.
Thanks to its very good compactness, the fully isolated SLLIMM-nano package (NDIP) is
the ideal solution for applications requiring reduced assembly space, without sacrificing
thermal performance and reliability.
Compared to discrete-based inverters, including power devices, and driver and protection
circuits, the SLLIMM-nano family provides a high integrated level that means simplified
circuit design, reduced component count, lower weight, and high reliability.
The aim of this application note is to provide a detailed description of SLLIMM-nano
products, providing guidelines to motor drive designers for an efficient, reliable, and fast
design when using the new ST SLLIMM-nano family.
