Description
The VND5004ATR-E and VND5004ASP30-E are
devices made using STMicroelectronics VIPower
technology. They are intended for driving resistive
or inductive loads with one side connected to
ground. Active V
CC
pin voltage clamp and load
dump protection circuit protect the devices
against transients on the Vcc pin (see ISO7637
transient compatibility table). These devices
integrate an analog current sense which delivers
a current proportional to the load current
(according to a known ratio) when CS_DIS is
driven low or left open. When CS_DIS is driven
high, the CURRENT SENSE pin is high
impedance. Output current limitation protects the
devices in overload condition. In case of long
duration overload, the devicesa limit the
dissipated power to a safe level up to thermal
shut-down intervention. Thermal shut-down with
automatic restart allows the device to recover
normal operation as soon as a fault condition
disappears.
