Description

■ Output current: 1 A per channel

■ Shorted load protections

The VNI4140K-32 is a monolithic device made

using STMicroelectronics VIPower technology,

intended for driving four independent resistive,

capacitive or inductive loads with one side

connected to ground. Active current limitation

avoids the system power supply dropping in the

case of shorted load. Built-in thermal shutdown

protects the chip from overtemperature and short-

circuit. In overload condition, the channel turns

OFF and back ON automatically so as to maintain

junction temperature between T_TSDand T_R. If this

condition causes case temperature to reach

■ 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

_CSD, the overloaded channel is turned OFF and

■ Open drain diagnostic outputs

■ 3.3 V CMOS/TTL compatible inputs

■ Fast demagnetization of inductive loads

■ Conforms to IEC 61131-2

restarts only when case temperature has

decreased down to T_CR. In the case of more than

one channel in overload, re-start of the

overloaded channels is not simultaneous, in order

to avoid high peak current from the supply. Non-

overloaded channels continue to operate

normally. The open drain diagnostic outputs

indicate overtemperature conditions.

■ ESD according to IEC 61000-4-2 up to +/-

25 KV

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 very carefully considered. Furthermore,

the available space on the PCB should be chosen considering the power dissipation.

Heatsinking 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

This schematic can be used with any type of load.

The following is an indication on how to dimension the R_GNDresistor.

_GND= (-V_CC) / (-I_GND

)

where -I_GNDis the DC reverse ground pin current and can be found in the absolute

maximum rating section of the device datasheet.

Power dissipation in R_GND(when V_CC< 0: during reverse polarity situations) is:

PD = (-V_CC)²/R_GND

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.
