• Output current: 1 A per channel
• Shorted load protections
• Junction overtemperature protection
• Case overtemperature protection for thermal
independence of the channels
• Thermal case shutdown restart not
simultaneous for the various channels
• Protection against loss of ground
• Current limitation
• Undervoltage shutdown
• Open drain diagnostic outputs
• 3.3 V CMOS/TTL compatible inputs
The VNI4140K-32 is a monolithic device made
using STMicroelectronics VIPower technology,
intended to drive four independent resistive,
capacitive or inductive loads with one side
connected to ground. Active current limitation
avoids the system power supply dropping in case
of shorted load. Built-in thermal shutdown
protects the chip from overtemperature and shortcircuit. In overload conditions, the channel turns
OFF and back ON automatically so to maintain
junction temperature between TTSD and TR. If this
condition causes case temperature to reach
TCSD, the overloaded channel is turned OFF and
restarts only when case temperature has
decreased down to TCR. In case of more than one
channel in overload, restart of the overloaded
channels is not simultaneous, in order to avoid
high peak current from the supply. Nonoverloaded channels continue operating normally.
The open drain diagnostic outputs indicate
overtemperature conditions.

Thermal management
Thermal management
The power dissipation in the IC is the main factor that sets the safe operating condition of
the device in the application. Therefore, it must be considered very carefully. Furthermore,
the available space on the PCB should be chosen considering the power dissipation. Heat
sinking can be achieved using copper on the PCB with proper area and thickness. Two
different protections have been implemented to guarantee safety of the device if it overheats
due to an overloaded condition or high environment temperature.The following flowchart
explains in detail this protection functionality.

Reverse polarity protection
Reverse polarity protection
Reverse polarity protection can be implemented on board using two different solutions:
1.
Placing a resistor (RGND) between IC GND pin and load GND
2.
Placing a diode between IC GND pin and load GND
If option 1 is selected, the minimum resistance value has to be selected according to the
following equation:
Equation 1
RGND ≥ VCC / IGND
where IGND is the DC reverse ground pin current and can be found in Section 2: Maximum
ratings of this datasheet.
Power dissipated by RGND (when VCC < 0: during reverse polarity situations) is:
Equation 2
PD = VCC2/RGND
If option 2 is selected, the diode has to be chosen by taking into account VRRM >|Vcc| and
its power dissipation capability:
Equation 3
PD ≥ IS*VF
Note:
In normal conditions (no reverse polarity), due to the diode, there is a voltage drop between
GND of the device and GND of the system.
