VN808CM-32-E
Octal channel high side driver
Features
■CMOS compatible input
■Junction overtemperature protection
■Case overtemperature protection for thermal
independence of the channels
■Current limitation
■Shorted load protection
■Undervoltage shutdown
■Protection against loss of ground
■Very low standby current
■Compliance to 61000-4-4 IEC test up to 4 kV
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. 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

6 Reverse polarity protection
This schematic can be used with any type of load.
The following is an indication on how to dimension the RGND resistor.
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.
Power dissipation in RGND (when VCC< 0: during reverse polarity situations) is:
PD = (-VCC)2/RGND
Note: In normal condition (no reverse polarity) due to the diode there will be a voltage drop
between GND of the device and GND of the system.
