European directive
The VN5010AK-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

– High current sense precision for wide range
currents
– Current sense disable
– Thermal shutdown indication
– Very low current sense leakage
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 shut-
down intervention. Thermal shut-down with
automatic restart allows the device to recover
normal operation as soon as fault condition
disappears.
■ Protections
– Undervoltage shut-down
– Overvoltage clamp
– Load current limitation
– Self limiting of fast thermal transients
– Protection against loss of ground and loss
of V
CC
– Thermal shut down
– Reverse battery protection (see Application
