DESCRIPTION
The VNQ810 is a quad HSD formed by
assembling two VND810 chips in the same SO-28
package. The VND810 is a monolithic device
made by using STMicroelectronics VIPower M0-3
Technology, intended for driving any kind of load
with one side connected to ground.
Active VCC pin voltage clamp protects the device
ABSOLUTE MAXIMUM RATING
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 detects open load condition both in on and
off state . Output shorted to VCC is detected in the
off state. Device automatically turns off in case of
ground pin disconnection.

OPEN LOAD DETECTION IN OFF STATE
Off state open load detection requires an external pull-up
resistor (RPU) connected between OUTPUT pin and a
positive supply voltage (VPU) like the +5V line used to
supply the microprocessor.
The external resistor has to be selected according to the
following requirements:
1) no false open load indication when load is connected:
in this case we have to avoid VOUT to be higher than
VOlmin; this results in the following condition
VOUT=(VPU/(RL+RPU))RL<VOlmin.
2) no misdetection when load is disconnected: in this
case the VOUT has to be higher than VOLmax; this
results in the following condition RPU<(VPU–VOLmax)/
IL(off2).
Because Is(OFF) may significantly increase if Vout is pulled
high (up to several mA), the pull-up resistor RPU should
be connected to a supply that is switched OFF when the
module is in standby.
The values of VOLmin, VOLmax and IL(off2) are available in
the Electrical Characteristics section.
