High Voltage 3-Phase Motor Driver ICs
SMA685½M Series
General Description
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.

NOTES:
● An arm short-circuit may occur when inputs on the HIN and LIN pins for the same phase are all
logic high. Therefore, extra attention should be paid to prevent a condition in which the pins for the
same phase are fully ON at once.
● A MOSFET in a V
CC
UVLO state gets re-activated when an input signal is detected at a certain logic
level (level triggering), while a MOSFET in a V
B
UVLO state resumes its operation at a point
where an input signal transits from one state to another (edge triggering).
