An Input and Asynchronous RESET, both TTL/CMOS compatible with wide voltage range
and high noise immunity (thanks to a built in hysteresis) are available.
5
Over temperature protection (OVT)
An on-chip Over Temperature Protection provides an excellent protection of the device in
extreme conditions. Whenever the temperature - measured on a central portion of the chip-
exceeds Tmax =150 °C (typical value) the device is shut off, and the DIAG output goes LOW.
Normal operation is resumed as the chip temperature (normally after few seconds) falls
below Tmax-Thys = 130 °C (typical value). The hysteresis avoid thats an intermittent
behaviour take place.
6
Under voltage protection (UV)
The supply voltage is expected to range from 8 to 35 V. In this range the device operates
correctly. Below 8V the overall system has to be considered not reliable. To avoid any
misfunctioning the supply voltage is continuously monitored to provide an under voltage
protection. As Vs falls below Vsth-Vshys (typically 7.5 V, see fig. 4) the output power MOS is
switched off and DIAG output goes LOW. Normal operation is resumed as soon as Vs
exceeds Vsth. The hysteretic behaviour prevents intermittent operation at low supply voltage.
8/16
L6377
Over current operation
7
Over current operation
In order to implement a short circuit protection the output power MOS is driven in linear
mode to limit the output current to the Isc value. This Isc limit is externally settable by means
of an external 1/4 W resistor connected from Rsc pin and GND. The value of the resistor
must be chosen according to the following formula:
I
(A) = 5/R (kΩ)
sc
sc
with
5 < R < 30 (kΩ)
sc
For
R
< 5 (kΩ)
sc
Isc is limited to Isc = 1.1 A (typical value).
This condition (current limited to the Isc value) lasts for a Ton time interval, that can be set
by means of a capacitor (C
formula:
) connected to the ON DELAY pin according to the following

Now two conditions may occur

the overload is still present. In this case the output power MOS is again driven in linear
mode (limiting the output current to Isc) for another t , starting a new cycle, or
ON
the overload condition is removed, and the output power MOS is no longer driven in
linear mode.
All these occurrences are presented on the DIAG pin (see fig 5). We call this unique feature
non dissipative short circuit protection and it ensures a very safe operation even in
permanent overload conditions. Note that, of course, choosing the most appropriate value
for the t interval (i.e. the value of the C
capacitor) a delay (the t itself) will prevent

that a misleading Short Circuit information is presented on the DIAG output, when driving
capacitive loads (that acts like short circuit in the very beginning) or Incandescent Lamp (a
cold filament has a very low resistive value).
The non dissipative short circuit protection can be disabled (keeping t = 0 but with the
ON
output current still limited to Isc, and Diagnostic disabled) simply shorting to ground the the
ON DELAY pin.

Demagnetisation of inductive loads

Demagnetisation of inductive loads
The L6377 has an internal clamping zener diode able to demagnetise inductive loads. Note
that the limitation comes from the peak power that the package can handle. Attention must
be paid to a proper thermal design of the board. If, for whatever reason (load current or
inductive value too big) the peak power dissipation is too high, an external Zener plus Diode
arrangement, can perform a demagnetisation versus Ground or versus Vs (see fig 5 and 6).
The breakdown voltage of the external Zener Diode must be chosen considering the internal
clamping voltage (Vcl) and the supply voltage (Vs) according to:
V < V
