Description

The VN920B5-E is a monolithic device designed

in STMicroelectronics™ VIPower™ M0-3

technology. The VN920B5-E is intended for

driving any type of load with one side connected

to ground.

The active V

pin voltage clamp protects the

device against low energy spikes (see ISO7637

transient compatibility table).

Active current limitation combined with thermal

shutdown and automatic restart protect the device

against overload.

The device integrates an analog current sense

output which delivers a current proportional to the

load current. The device automatically turns off in

the case where the ground pin becomes

disconnected.

The following is an indication on how to dimension the RGND resistor. 1. RGND ≤ 600 mV / (IS(on)max) 2.
PAGE 17
VN920B5-E 3.1.2 Application information Solution 2: diode (DGND) in the ground line A resistor (RGND = 1 kΩ) should be inserted in parallel to DGND if the device drives an inductive load. This small signal diode can be safely shared amongst several different HSDs. Also in this case, the presence of the ground network produces a shift (≈600mV) in the input threshold and in the status output values if the microprocessor ground is not common to the device ground.
