Description
The VND5050AJ-E, VND5050AK-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 V
CC
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.
