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.
