The VND5E050J-E and VND5E050K-E are designed to drive automotive grounded loads delivering protection, diagnostics and easy 3V and 5V CMOS-compatible interface with any microcontroller. The devices integrate advanced protective functions such as load current limitation, inrush and overload active management by power limitation, over temperature shut-off with auto-restart and over-voltage active clamp. A dedicated active low digital status pin is associated with every output channel in order to provide Enhanced diagnostic functions including fast detection of overload and short-circuit to ground, over temperature indication, short-circuit to VCC diagnosis and on & off-state open-load detection. The diagnostic feedback of the whole device can be disabled by pulling the STAT_DIS pin up, thus allowing wired-ORing with other similar devices. ■ ■ July 2009 Doc ID 14472 Rev 3 1/40 www.st.com 1 Contents VND5E050K-E Contents 1 2 Block diagram and pin description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 Electrical specifications . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 2.1 2.2 2.3 2.4 2.5 Absolute maximum ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 Waveforms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 Electrical characteristics curves . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 19 3 Application information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 22 3.1 GND protection network against reverse battery . . . . . . . . . . . . . . . . . . . 22 3.1.1 3.1.2 Solution 1: resistor in the ground line (RGND only) . . . . . . . . . . . . . . . . 22 Solution 2: diode (DGND) in the ground line . . . . . . . . . . . . . . . . . . . . . 23 3.2 3.3 3.4 3.5 Load dump protection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23 MCU I/Os protection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23 Open-load detection in off-state . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 24 Maximum demagnetization energy (VCC = 13.5V) . . . . . . . . . . . . . . . . . 25 4 Package and PCB thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 26 4.1 4.2 PowerSSO-12 thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 26 PowerSSO-24 thermal data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 29 5 Package and packing information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 32 5.1 5.2 5.3 5.4 5.5 ECOPACK® packages . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 32 PowerSSO-12 package information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 32 PowerSSO-24 package information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 34 PowerSSO-12 packing information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36 PowerSSO-24 packing information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 37 6 7 Order codes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 38 Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 39 2/40 Doc ID 14472 Rev 3 VND5E050K-E List of tables List of tables Table 1.
