Description
The VN808CM-32-E is a monolithic device
designed in STMicroelectronics VIPower M0-3
technology, intended for driving any kind of load
with one side connected to ground.

PowerSO-36
It can be driven by using a 3.3 V logic supply.
Active current limitation combined with thermal
shutdown and automatic restart, protect the
device against overload. In overload condition,
channel turns OFF and back ON automatically so
as to maintain junction temperature between TTSD
and TR. If this condition makes case temperature
reach TCSD, overloaded channel is turned OFF
and will restart only when case temperature has
decreased down to TCR(see waveform 3 Figure 6
on page 10). Non overloaded channels continue
to operate normally. Device automatically turns
OFF in case of ground pin disconnection. This
device is especially suitable for industrial
applications conform to IEC 61131

Reverse polarity protection
Reverse polarity protection
A schematic solution to protect the IC against a reverse polarity condition is proposed.
This schematic is effective with any type of load connected to the outputs of the IC.
The RGND resistor value can be selected according to the following conditions to be met:
1.
RGND ≤ 600 mV / (IS in ON state max).
2.
RGND ≥ (-VCC) / (-IGND)
where -IGND is the DC reverse ground pin current and can be found in the absolute
maximum rating section of the device datasheet.
The power dissipation associated to RGNG during reverse polarity condition is:
PD = (-VCC)2/RGND
This resistor can be shared by several different ICs. In such case IS value on formula (1) is
the sum of the maximum ON-state currents of the different devices.
Please note that if the microprocessor ground and the device ground are separated then the
voltage drop across the RGND (given by IS in ON state max * RGND) produce a difference
between the generated input level and the IC input signal level. This voltage drop will vary
depending on how many devices are ON in the case of several high side switches sharing
the same RGND.
