DESCRIPTION

The VN16B 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

and overtemperature. Fast demagnetization

V

CC

of inductive loads is achieved by negative (-18V)
load voltage at turn-off.

Note: 2. The maximum continuous output current is the current at

Tc = 85 °C for a battery voltage of 13 V which does not
activate self protection.

FUNCTIONAL DESCRIPTION

The device has a diagnostic output which
indicates open load in on-state, open load in off­state, over temperature conditions and stuck-on to

.

V

CC

From the falling edge of the input signal, the status
output, initially low to signal a fault condition
(overtemperature or open load on-state), will go
back to a high state with a different delay in case
of overtemperature (t

) respectively. This feature allows to

(t

pol

discriminate the nature of the detected fault. To
protect the device against short circuit and over
current condition, the thermal protection turns the
integrated Power MOS off at a minimum junction
temperature of 140 °C. When this temperature
returns to 125 °C the switch is automatically turned
on again. In short circuit the protection reacts with
virtually no delay, the sensor being located inside
the Power MOS area. An internal function of the
devices ensures the fast demagnetization of
inductive loads with a typical voltage (V

-18V. This function allows to greatly reduces the
power dissipation according to the formula:

according to the above formula. In this device if the

not exceeding

16V, it will switch off.

PROTECTING THE DEVICE AGAINST
REVERSE BATTERY

The simplest way to protect the device against a
continuous reverse battery voltage (-26V) is to
insert a Schottky diode between pin 1(GND) and
ground, as shown in the typical application circuit
(Figure 10).

The consequences of the voltage drop across this
diode are as follows:

– If the input is pulled to power GND, a negative

voltage of -V
thresholds and V

is seen by the device. (VIL, VIH

f

are increased by Vf with

STAT

respect to power GND).

– The undervoltage shutdown level is increased

.

by V

f

If there is no need for the control unit to handle
external analog signals referred to the power

)/

GND, the best approach is to connect the
reference potential of the control unit to node [1]
(see application circuit in Figure 10), which
becomes the common signal GND for the whole
control board avoiding shift of V

, VIL and V

IH

This solution allows the use of a standard diode.
