Per channel Description 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 Fast demagnetization of inductive loads Conforms to IEC 61131-2 ESD according to IEC 61000-4-2 up to +/25 KV Figure 1. PowerSSO-24 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 shortcircuit. In overload condition, the channel turns OFF and back ON automatically so as 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 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. Nonoverloaded channels continue to operate normally. The open drain diagnostic outputs indicate overtemperature conditions.

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. Figure 5.

The following is an indication on how to dimension the RGND resistor. RGND = (-VCC) / (-IGND) where -IGND is the DC reverse ground pin current and can be found in the absolute maximum rating section of the device datasheet. Power dissipation in RGND (when VCC < 0: during reverse polarity situations) is: PD = (-VCC)2/RGND 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.
