Description
The VN5770AK-E 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
SO-28
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 the case of long
overload duration, the device limits the dissipated
power to a safe level up to thermal shut-down
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.
Applications
■ DC motor driving in full or half bridge
configuration
■ All types of resistive, inductive and capacitive
loads
