Application All types of resistive, inductive and capacitive
loads
DescriptionThe VN5012AK-E is a monolithic device made
using STMicroelectronics VIPower® M0-5
technology. It is intended for driving resistive or
inductive loads with one side connected to
ground. Active VCC pin voltage clamp protects the
device against low energy spikes (see ISO7637
transient compatibility table). This device
integrates 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 in a high
impedance condition. Output current limitation
protects the device in overload condition. In case
of long overload duration, the device limits the
dissipated power to safe level up to thermal
shutdown intervention. Thermal shutdown with
automatic restart allows the device to recover
normal operation as soon as fault condition
disappears.
