VND5004B: dual 4 m smart high side switch VIPowerTM M0-5 solution for power management in automotive applications The VND5004B from STMicroelectronics is a dual-channel low RDS(ON) device (4 m per channel) in VIPowerTM 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 Main applications Dual high side for automotive application Low on-state resistance (4 m per channel) Only 2 A 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 www.st.com Power management Diesel glow plugs Seat heating Multi-bulb loads (lighting) Most high-current resistive, inductive and capacitive loads Package options MultiPowerSO-30 Power QFN (12 x 12 power lead less package) VND5004B block diagram Vcc Vcc clamp GND Under voltage Reverse battery protection Power clamp Driver Overtemperature IOUT1 CS_DIS Power limitation Output 1 K Current sense 1 Power clamp Logic Input 1 ILIM Driver ILIM Output 2 K Current sense 2 Overtemperature Input 2 Power limitation CS_DIS According to the innovative protection strategy introduced in VIPowerTM 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.
