The VNB49N04, VNV49N04 are monolithic devices
designed in STMicroelectronics™ VIPower™ M0
technology, intended for replacement of standard
Power MOSFETs from DC up to 50 KHz
applications.
Built-in thermal shutdown, linear current limitation
and overvoltage clamp protect the chip in harsh
environments.
Fault feedback can be detected by monitoring the
voltage at the input pin.
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to the conditions in table below for extended
periods may affect device reliability. Refer also to the STMicroelectronics SURE Program
and other relevant quality document.

Protection features VNB49N04 - VNV49N04
3 Protection features
During normal operation, the INPUT pin is electrically connected to the gate of the internal
power MOSFET. The device then behaves like a standard power MOSFET and can be used
as a switch from DC up to 50 KHz. The only difference
from the user’s standpoint is that a small DC current (IISS) flows into the INPUT pin in order
to supply the internal circuitry.
The device integrates:
●Overvoltage clamp protection:
Internally set at 42V, along with the rugged avalanche characteristics of the Power
MOSFET stage give this device unrivalled ruggedness and energy handling capability.
This feature is mainly important when driving inductive loads.
●Linear current limiter circuit:
Limits the drain current ID to ILIM whatever the INPUT pin voltage. When the current
limiter is active, the device operates in the linear region, so power dissipation may
exceed the capability of the heatsink. Both case and junction temperatures increase,
and if this phase lasts long enough, junction temperature may reach the
overtemperature threshold Tjsh.
●Overtemperature and short circuit 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, accurate detection of the junction temperature. Overtemperature cutout
occurs at minimum 150 °C. The device is automatically restarted when the chip
temperature falls below 135 °C.
●Status feedback:
In the case of an overtemperature fault condition, a status feedback is provided through
the INPUT pin. The internal protection circuit disconnects the input from the gate and
connects it instead to ground via an equivalent resistance of 100Ω. The failure can be
detected by monitoring the voltage at the INPUT pin, which will be close to ground
potential. 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 (with a small increase
in R
DS(ON)
).
