Description

The VN920SP-E is a monolithic device designed

in STMicroelectronics™ VIPower™ M0-3

technology. The VN920SP-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 protects 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.

Application schematic +5V VCC Rprot INPUT Dld μC Rprot OUTPUT CURRENT SENSE RSENSE GND VGND RGND DGND 3.1 GND protection network against reverse battery 3.1.1 Solution 1: resistor in the ground line (RGND only) This can be used with any type of load. The following is an indication on how to dimension the RGND resistor. 1. RGND ≤ 600 mV / (IS(on)max) 2.
PAGE 18
Application information 3.1.2 VN920SP-E 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.
