Description
The Root part number 1 is a device formed by
three monolithic chips housed in a standard SO-
28 package: a double high-side and two low-side
switches. The double high-side is made using
STMicroelectronics^® VIPower^® M0-5 technology,
while the low-side switches are fully protected
VIPower M0-3 OMNIFET II. This device is suitable
to drive a DC motor in a bridge configuration as
well as to be used as a quad switch for any low
voltage application.
The dual high-side switches integrate built in non
latching thermal shutdown with thermal
hysteresis. An output current limiter protects the
device in overload condition. In case of long
overload duration, the device limits the dissipated
power to a safe level up to thermal shutdown
intervention. An analog current sense pin delivers
a current proportional to the load current
(according to a known ratio) and indicates
overtemperature shutdown of the relevant high-
side switch through a voltage flag.
The low-side switches have built in non latching
thermal shutdown with thermal hysteresis, linear
current limitation and overvoltage clamping.
Fault feedback for overtemperature shutdown of
the low-side switch is indicated by the relevant
input pin current consumption going up to the fault
sink current flag.
