VND830AEP-E

VND830AEP-E Double channel high side driver Features Type RDS(on) IOUT VCC VND830AEP-E 60mΩ(1) 6A(1) 36V 1. Per each channel. PowerSSO-24 ■ DC short circuit current: 6A ■ CMOS compatible inputs ■ Proportional load current sense ■ Undervoltage and overvoltage shutdown ■ Overvoltage clamp ■ Thermal shutdown ■ Current limitation ■ Very low standby power dissipation ■ Protection against loss of ground and loss of VCC ■ Reverse battery protection(a) ■ In compliance with the 2002/95/EC european directive Description The VND830AEP-E is a monolithic device made using| STMicroelectronics VIPower™ M0-3 Technology. The VND830AEP-E is intended for driving any type of multiple load with one side connected to ground. The Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). This device has two channels in high side configuration; each channel has an analog sense output on which the sensing current is proportional (according to a known ratio) to the corresponding load current. Built-in thermal shutdown and outputs current limitation protect the chip from over temperature and short circuit. The device automatically turns off in the case where the ground pin becomes disconnected. a. See Application schematic on page 16 Table 1.
