Description
The device is a DC motor driver for automotive
applications. It integrates a full protected dual
high-side driver and the drivers and protections
for the two external power MOSFETs in low-side
configuration.
The device is designed using STMicroelectronics’
well known and proven proprietary VIPower® M0
technology that allows to efficiently integrate on
the same die a true PowerMOSFET with an
intelligent signal/ protection circuitry. The device
is housed in a PowerSSO-36 exposed pad
package to optimize the dissipation
performances.
The input signals INA and INB can directly
interface the microcontroller to select the motor
direction and the brake conditions. Two selection
pins (SEL0 and SEL1) are available to address to
the microcontroller the information available on
the MultiSense. The MultiSense pin allows to
monitor the motor current, provides a voltage
proportional to the battery value and the
information on the temperature of the chip. The
integrated protections are: load current limitation,
overload active power limitation (with latch-off),
overtemperature shutdown (with latch-off) and
cross current protection.
