Note: 1. In= Nominal current according to ISO definition for high
side automotive switch. The Nominal Current is the
current at T
c
= 85 °C for battery voltage of 13V which
produces a voltage drop of 0.5 V.

Note: 2. The maximum continuous output current is the current at
T
c
= 85 °C for a battery voltage of 13 V which does not
activate self protection.
DESCRIPTION
The VN31 is a monolithic device made using
STMicroelectronics VIPower Technology,
intended for driving resistive or inductive loads
with one side grounded.
Built-in thermal shut-down protects the chip from
over temperature and short circuit.
The open drain diagnostic output indicates: open
load in off state and in on state, output shorted to
V
CC
and overtemperature. Fast demagnetization
of inductive loads is achieved by negative (-18V)
load voltage at turn-off.
