Description

EV-VNQ5E050AK provides you an easy way to

connect ST’s surface mounted VIPower

drivers

into your existing prototype circuitry. This

evaluation board comes pre-assembled with

VNQ5E050AK-E high-side driver.

The VNQ5E050AK-E is a quad channel

high-side driver manufactured using ST

proprietary VIPower M0-5 technology and housed

in PowerSSO-24 package. The VNQ5E050AK-E

is designed to drive 12 V automotive grounded

loads, providing protection, diagnostics and easy

3 V and 5 V CMOS-compatible interface with any

microcontroller.

The device integrates advanced protective

functions such as load current limitation, inrush

and overload active management by power

limitation, overtemperature shut-off with auto-

restart and overvoltage active clamp. A dedicated

analog current sense pin is associated with every

output channel provides enhanced diagnostic

functions including fast detection of overload and

short-circuit to ground through power limitation

indication, overtemperature indication, short-

circuit to V

diagnosis and ON-state and

OFF-state open-load detection.

The current sensing and diagnostic feedback of

the whole device can be disabled by pulling the

CS_DIS pin high to share the external sense

resistor with similar devices.

Design recommendations 1 EV-VNQ5E050AK Design recommendations This evaluation board provides mounting solution and some heat sinking capability for prototype development, but there are still external components that are required to make these devices work in any application. For further information on how the evaluation board has to be used you can refer to the AN4212 (see Appendix A: Reference documents). Figure 2 illustrates the necessary components for any application. Figure 2.
