production data
Features
•V
CC
/2 compatible input
•Junction overtemperature protection
•Case overtemp er ature pr otecti on for therm al
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 VN808-32-E is a monolithic device designed
in STMicroelectronics VIPower M0-3 technology,
intended to drive any kind of load with one side
connected to ground. Active current limitation
combined with thermal shutdown and automatic
restart, protect the device against overload. In
overload condition, the channel turns off and on
again automatically so to maintain the junction
temperature between T
TSD
and T
R
. If
this
condition makes case temperature reach T
CSD
,
overloaded channels are turned off and restart
only when the case temperature decreases down
to T
CR
. Non-overloaded channels continue to
operate normally . Device automatically turns off in
case of ground pin disconnection. This device is
especia ll y su itab le for indus tr ia l appl ic ati ons
conform to IEC 61131.

6 Reverse polarity protection
Reverse polarity protection can be implemented on board using two different solutions:
1. Placing a resistor (R
GND
) between IC GND pin and load GND
2. Placing a diode between IC GND pin and load GND
If option 1 is selected, the minimum resistance value has to be selected according to the
following equation:
Equation 1
R
GND
≥
V
CC
/I
GND
where I
GND
is the DC reverse ground pin current and can be found in Section 1: Maximum
ratings of this datasheet.
Power dissi pated by R
GND
(when V
CC
< 0: during reverse polarity situations) is:

= (V

If option 2 is selected, the diode has to be chosen by taking into account VRRM >|V

its power dissipation capability:

Note: In normal conditions (no reverse polarity) due to the diode, there is a voltage drop between
