The VND5004B from STMicroelectronics is a dual-channel
low RDS(ON) device (4 mΩ per channel) in VIPower™
M0-5 technology.
Part of the intelligent power switch family, this device is
equipped with several diagnostic functions, able to protect
itself and the load against hazardous conditions. Moreover,
under reverse battery conditions, the dissipated power is
limited by power stage self turn-on.
Specifically intended for power management, the
VND5004B is suitable to automotive applications requiring
high operating current.
Key features
■ Dual high side for automotive application
■ Low on-state resistance (4 mΩ per channel)
■ Only 2 µA of standby current
■ Proportional load-current sense output with thermal
shutdown indication
■ Very low electromagnetic susceptibility and optimized
electromagnetic emission
Embedded protections
■ Reverse battery protection by automatic PowerMOS
switch-on
■ Active management of hazardous conditions by
power limitation
■ Load-current limitation (100 A typ.)
■ Thermal shutdown
■ Under-voltage shutdown
■ Over-voltage clamp
■ Protection against loss of ground and loss of Vcc
■ Electrostatic discharge protection

According to the innovative protection strategy
introduced in VIPower™ M0-5 technology, the VND5004B
is equipped with power limitation control removing the
thermal fatigue, main cause of silicon degradation.
Moreover, under reverse battery condition the device
is protected by PowerMOS reactivation.
