1.1

Product synopsis

The SLLIMM-nano family has been designed to satisfy the requirements of a wide range of

final applications up to 100 W (in free air), such as:

●

dish washers

●

refrigerator compressors

●

air conditioning fans

●

draining and recirculation pumps

●

low power industrial applications

●

small fans, pumps and tools.

The main features and integrated functions can be summarized as follows:

●

600 V, 3 A ratings

●

3-phase IGBT inverter bridge including:

–

six low-loss IGBTs

–

six low forward voltage drop and soft recovery freewheeling diodes

●

three control ICs for gate driving and protection including:

–

smart shutdown function

–

comparator for fault protection against overcurrent and short-circuit

–

op amp for advanced current sensing

–

three integrated bootstrap diodes

–

interlocking function

–

undervoltage lockout

●

open emitter configuration for individual phase current sensing

●

very compact and fully isolated package

●

integrated gate resistors for IGBT switching speed optimum setting

●

gate driver proper biasing.
