the chip in harsh environments.
Fault feedback can be detected by monitoring the
voltage at the input pin.

PROTECTION FEATURES
- OVERTEMPERATURE AND SHORT CIRCUIT
During normal operation, the INPUT pin is
electrically connected to the gate of the internal
power MOSFET through a low impedance path.
PROTECTION: these are based on sensing the
chip temperature and are not dependent on the
input voltage. The location of the sensing element
on the chip in the power stage area ensures fast,
The device then behaves like a standard power accurate detection of the junction temperature.

50KHz. The only difference from the user’s 190 °C, a typical value being 170 °C. The device is
standpoint is that a small DC current IISS (typ. automatically restarted when the chip temperature

stage give this device unrivalled ruggedness and
cenergy handling capability. This feature is mainly
uimportant when driving inductive loads.
d- LINEAR CURRENT LIMITER CIRCUIT: limits
rothe drain current ID to Ilim whatever the INPUT pin
voltage. When the current limiter is active, the
Pdevice operates in the linear region, so power

heatsink. Both case and junction temperatures

overtemperature fault condition (Tj > Tjsh), the
device tries to sink a diagnostic current Igf through
the INPUT pin in order to indicate fault condition. If
driven from a low impedance source, this current
may be used in order to warn the control circuit of
a device shutdown. If the drive impedance is high
enough so that the INPUT pin driver is not able to
supply the current Igf, the INPUT pin will fall to 0V.
This will not however affect the device
operation: no requirement is put on the current
capability of the INPUT pin driver except to be
able to supply the normal operation drive
current IISS.
Additional features of this device are ESD
protection according to the Human Body model
and the ability to be driven from a TTL Logic
circuit.
