Description

The VNB14NV04, VND14NV04, VND14NV04-1 and

VNS14NV04 are monolithic devices made using

STMicroelectronics VIPower™ M0 technology,

intended for replacement of standard power

MOSFETS in DC 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.

3 Protection features

During normal operation, the input pin is electrically connected to the gate of the internal

power MOSFET through a low impedance path.

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 (typ. 100 µA) flows into the input pin in order to supply the internal circuitry.

The device integrates:

● Overvoltage clamp protection: internally set at 45 V, 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

voltages. 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 over temperature threshold Tjsh.

●Over temperature 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. Over temperature cutout occurs in the range 150 to 190 °C, a

typical value being 170 °C. The device is automatically restarted when the chip

temperature falls of about 15 °C below shutdown temperature.

●Status feedback: in the case of an over temperature 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 0 V.

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.
