Description
The SX68000MH series provides the solution for controlling
3-phase full bridges that utilize MOSFETs rated at 250 V/2 A,
500 V/1.5 A, or 500 V/2.5 A.
The IC includes in a single package: protection functions such as
UVLO (protection circuit for controlling power supply voltage
drop), OCP (overcurrent protection), TSD (thermal shutdown),
and OCL (current limiting), and a pre-driver with ¯F¯O¯ (Fault
Output) terminal and bootstrap diodes with limit resistors.
The SX68000MH series is packaged in a fully-molded SOP with
27 pins at 1.2 mm pitch. Body size: 22 Ã 14.1 Ã 2.1 mm.
Package: 27-pin SOP
