Product Information
High Voltage SLA6860M and SMA6860M Series
Driver ICs for 3-Phase DC Motor Applications
Leadform 2451
Introduction
The SLA6860M and SMA6860M Series consists of inverter
power module (IPM) devices that integrate within a single,
compact package: power MOSFETs, pre-driver ICs, and fast
recovery diodes. These products are especially suitable for
driving the inverters of low-capacity motors, such as those
used in 100 to 200 V fans or pumps for air conditioners.

Leadform 2452
Features and benefits include the following:
▪ Three built-in bootstrap fast recovery diodes (FRD),
each with current-limiting resistor, and capable of
withstanding high voltages: 600 V at 1 A
▪ Overcurrent limiting (OCL) function, with fault signal
output and shutdown input terminal; when the user-
determined maximum current level is exceeded, PWM
on-off cycling is initiated to effectively limit current
▪ Built-in overcurrent protection (OCP) function; when an
overcurrent condition, such as an output short circuit, is
detected, the internal high-side and low-side logic ICs
shut down the output driver gates and issue a fault signal
▪ Optional automatic shutdown of high-side and low-side
gates if an abnormal condition occurs (overtemperature,
overcurrent, undervoltage on control power supply, and
so forth); enabled by connecting together the SD1 and
SD2 terminals
▪ Built-in overtemperature protection for both high-side
and low-side circuits; thermal shutdown (TSD) occurs
when the temperature of the logic chips exceed a user-
determined value, the internal high-side and low-side
logic ICs shut down the output driver gates and issue a
fault signal

Figure 1. SMA6860M Series packages are SIPs, offering compact
configurations both with heatsink pad (leadforms 2171 and 2175)
and without (leadforms 2451 and 2452). Both horizontal mount and
vertical mount are available.
▪ Built-in undervoltage lockout (UVLO) protection for
each control power supply, VCC1, VCC2, and VBx;
when voltage falls below a set value, the gates are shut
down and VCC1 and VCC2 output an alarm signal
▪ Alarm signal (shutdown) output when protection circuits
enable; high-side faults (UVLO and TSD) are signaled
on the SD1 terminal, low-side faults (TSD, OCP, and
UVLO) are signaled on the SD2 terminal
