High Voltage 3-Phase Motor Driver ICs
SMA685ｘM Series
March, 2015
General Description
Package
The SMA685xM series provides a highly-integrated
solution by incorporating key components into one package –
MOSFETs in a 3-phase full-bridge configuration, built-in
protection functions such as UVLO (undervoltage lockout) and
TD (thermal detection) circuits, pre-driver ICs with 7.5 V
regulator output, and bootstrap diodes with limiting resistors.
The products are capable of detecting overcurrent through
three shunt resistors. And their packages are fully-molded
SIPs.
● Package Name: SMA
